V2 parse & extract SDK support (implementation plan)

[yzld2002]

Full code-level plan: docs/superpowers/plans/2026-07-07-v2-parse-extract-ade-python.md (13 TDD tasks with complete code + test cycles). This issue is the summary — GitHub's 64 KB body limit won't hold the full plan.

Scope: ade-python only (TS is a separate port). Additive client.v2 sub-client for V2 parse, V2 extract, their async job routes, and file staging — routed to the ADE host — with hand-written ergonomics (unified Job, wait() polling, pydantic-schema acceptance, save_to parity).

---

Contract verification (against the real openapi.json)

Verified all 13 routes. Several items in the design doc's table were stale/wrong; the plan encodes the corrected reality:

1. idempotency_key is extract-only — absent from every parse route in the spec.
2. 206 partial-success is on parse, not extract. POST /v2/parse returns 206 with metadata.failed_pages; POST /v2/extract returns only 200/422 — strict-mode failure is 422.
3. Encrypted PDFs are supported — both parse routes accept password. (Doc item "password → 422" is obsolete.)
4. Parse result is untyped in the spec (prose only); extract is typed (V2ExtractResult/V2ExtractMetadata). V2 parse metadata differs from V1's.
5. Envelope divergence is worse than flagged:

	parse job	extract job
timestamps	received_at, created_at — int epoch secs	created_at, completed_at — ISO strings
terminal payload	data (inline) or output_url	result
failure	failure_reason (string)	error {code, message}
status enum	+cancelled	no cancelled
list envelope	{jobs, org_id, has_more}	{jobs, page, page_size, has_more}

Even within extract, list uses failure_reason but get uses error{code,message}.

6. /v1/files: single file part in, open {string:string} map out (file_ref is a key). Lives on the ADE host.
7. /v2/workflow: full third parallel surface (sync + jobs + get + list). Out of scope here, but the resource/waiter machinery accepts it later with no rework.
8. No cancel endpoint despite parse's cancelled status. Sync routes can 504 on timeout (extract 504 ⇒ workflow cancelled; retry w/ same idempotency_key restarts).

---

Design decisions

• Unified Job shape (chosen): one normalized model for parse + extract — status (common enum), created_at/completed_at (datetime, both int-epoch and ISO normalized via the existing parse_datetime), progress (float), result (typed: V2ParseResponse | V2ExtractResult), error (JobError), plus a .raw escape hatch for envelope-specific fields (org_id, output_url, version). Stable if aide unifies the API later.
• Routing needs no new HTTP client. The transport's _prepare_url passes absolute URLs through untouched, so v2 resources build absolute URLs against a resolved _v2_base_url and inherit auth/retries/http client. /v1/files routes to the ADE host despite its /v1 path.
• Environment = the whole user-facing story. 4-entry matrix of (V1, V2) host pairs; LANDINGAI_ADE_ENVIRONMENT env var; explicit base_url/v2_base_url overrides; if only base_url is set, V2 follows it (one mock captures everything).
• Generated-file edits are minimal & additive — _client.py (env map, v2_base_url resolution, one v2 cached property per client, widened environment Literal) + two re-exports. All other V2 code is new files under types/v2/, resources/v2/, lib/. Holds whether or not the Stainless exit ("Problem 1") has landed.
• Schema acceptance: v2.extract takes a pydantic model class, a dict, or a JSON string (extends lib/schema_utils.py), sent as a JSON object in the request body.

Task breakdown (13 TDD tasks)

Each task ends with an independently testable deliverable and a commit. Full code in the plan doc.

1. Environment map + dual base-URL resolution — _client.py (sync+async): 4-pair map, v2_base_url param, LANDINGAI_ADE_ENVIRONMENT/LANDINGAI_ADE_V2_BASE_URL, _v2_base_url attr, widened environment Literal, copy(). Tests: tests/test_v2_environment.py.
2. V2 types — types/v2/{job,parse_response,extract_response,file_upload_response}.py: JobStatus/JobError/Job, V2ParseResponse+metadata+billing, V2ExtractResult+V2ExtractMetadata, V2FileUploadResponse. Tests: tests/test_v2_types.py.
3. Job normalizers — resources/v2/_normalize.py: normalize_parse_job, normalize_extract_job (epoch vs ISO, data/result, failure_reason/error). Tests: tests/test_v2_normalize.py.
4. Schema coercion — lib/schema_utils.py: coerce_schema_to_dict(pydantic|dict|str) -> dict. Tests: tests/test_v2_schema.py.
5. V2 errors + 504 wrapper — lib/v2_errors.py: V2SyncTimeoutError, JobWaitTimeoutError, JobFailedError, raise_if_sync_timeout. Tests: tests/test_v2_errors.py.
6. v2 sub-client + routing + waiter — resources/v2/{_base,v2}.py: V2ResourceMixin._v2_url, poll_until_terminal/apoll_until_terminal (injected clock/sleep), V2Resource/AsyncV2Resource, client.v2 cached properties. Tests: routing via respx.
7. client.v2.files.upload — resources/v2/files.py → returns file_ref, hits ADE host. Tests: tests/api_resources/v2/test_files.py.
8. client.v2.parse (sync) — resources/v2/parse.py: options JSON-encoded, 206 returns response with failed_pages, 504 → V2SyncTimeoutError, save_to. Tests: tests/api_resources/v2/test_parse.py.
9. client.v2.parse_jobs — create/list/get/wait returning normalized Job; JobList carries has_more/org_id; priority, output_save_url. Tests appended.
10. client.v2.extract (sync) — resources/v2/extract.py: JSON body, schema coercion, idempotency_key, options.strict, 504 handling, save_to. Tests: tests/api_resources/v2/test_extract.py.
11. client.v2.extract_jobs — create/list/get/wait; maps error{code,message}, page/page_size envelope. Tests appended.
12. Async parity + full suite/lint/typecheck — async smoke tests; rye run pytest -q; rye run lint. Tests: tests/api_resources/v2/test_async_smoke.py.
13. Docs & examples — api.md V2 section, README V2 subsection, examples/v2_parse.py, examples/v2_extract.py.

Open items for the aide team (non-blocking)

• Parse idempotency_key: absent from parse routes though present on extract — confirm intent.
• Envelope unification before GA (normalizers collapse toward identity; public Job shape unaffected).
• /v2/workflow scope confirmation.
• Typed parse response: V2ParseResponse is permissive until the gateway publishes a typed schema.
• 504 retries: transport retries 5xx (incl. 504) before conversion — consider suppressing retries for sync 504s in a follow-up.

Build order & pipeline vs. hand-authored split

Recording the sequencing decision from the design doc so it lives next to this plan.

Order (per the design doc): Problem 1 (get off Stainless, ~2 days) → Problem 3 proven on V1 → Problem 2 (V2) once aide exposes the spec, with the pipeline then extending to V2.

Why the pipeline (Problem 3) goes first — dependency, not preference:

• Problem 3 needs nothing from V2. It runs against the already-public V1 spec, and its inaugural change is the known V1 drift bug — the 3 /v1/ade/extract/jobs routes neither SDK implements (PR feat: add async extract jobs support to SDK #93 hand-starts this; reconcile, don't duplicate). This validates the full loop (mechanical codegen commit → Claude Code Action wiring commit → surface-lock/contract gates) on a real, low-risk change before any V2 code exists.
• Problem 2's automation is gated on the one aide ask: serving the curated V2 openapi.json unauthenticated (401 today). Until then, no V2 contract tests against staging and no pipeline-to-V2 wiring.

Key nuance — "the pipeline extends V2 automatically" ≠ the pipeline builds all of V2. The pipeline only derives what's in the spec (plain types + additive endpoint wiring). It cannot invent the bespoke ergonomics this plan is mostly about.

Pipeline can generate (Problem 3)	Must be hand-authored (this plan / Problem 2)
types/v2/* request/response models	Dual-host routing + 4-env matrix (Task 1)
Additive resource/method stubs from spec diffs	Unified Job normalization across divergent envelopes (Tasks 2–3)
api.md / README surface updates	wait() waiters, pydantic-schema coercion, save_to, 504 handling (Tasks 4–11)

The pipeline extends an established surface and conventions. This plan is that architecture.

Concrete implication for Task 2: if Problem 3 is live before we build V2, the plain types/v2/* (Task 2) can be generated by the pipeline's datamodel-code-generator step instead of hand-written — we'd hand-write only the ergonomics tasks (the "hybrid" split). If V2 is urgent and the aide spec-exposure slips, build the whole plan by hand now against the committed openapi.json snapshot and let the pipeline take over sync maintenance later. The resulting code is identical; only who authors the plain types changes.

Recommendation: follow the doc — Problem 1, then prove Problem 3 on the V1 extract/jobs gap (unblocked now, fixes real drift), and push the aide spec-exposure ask in parallel so Problem 2 is unblocked. Decide Task 2 (generate vs. hand-write types) based on whether the pipeline is live when V2 work starts.

Correction (2026-07-08): V2 host is aide.[env], not api.ade.[env]

The environment matrix in the description above is wrong for the V2 hosts. Now that the curated V2 spec is public (https://aide.staging.landing.ai/openapi.json), the routing was confirmed against each host's openapi.json:

• aide.[env].landing.ai = the AIDE gateway — serves the V2 customer surface API and spec (title "AIDE Gateway": /v2/parse, /v2/extract, /v2/workflow, /v1/files).
• api.ade.[env].landing.ai = the VTRA "Vision Tools API" (V1 /v1/ade/* + /v1/tools/*, 51 paths); it does not serve /v2/parse|extract|workflow or /v1/files. Do not point the SDK or codegen at it for V2.

(Unauthenticated GET probes of these POST routes return contradictory codes — 401/307/404 — so the spec content is the source of truth, not probe status codes.)

Corrected environment matrix

environment	V1 base URL	V2 base URL
production (default)	https://api.va.landing.ai	https://aide.landing.ai
eu	https://api.va.eu-west-1.landing.ai	https://aide.eu-west-1.landing.ai
staging	https://api.va.staging.landing.ai	https://aide.staging.landing.ai
dev	https://api.va.dev.landing.ai	https://aide.dev.landing.ai

Since V2 API and spec share the aide.[env] host, there's no spec-host/API-host split, and the spec-sync pipeline fetches V2 drift from aide.[env]/openapi.json (same host the SDK calls). V1 is unchanged.

The plan doc in #96 has been updated accordingly (env matrix, V2_ENVIRONMENTS, and all test URLs). Everything else in the plan stands — the contract is verified against the live spec.

Correction #2 (2026-07-08) — supersedes my earlier "V2 host = aide.[env]" comment

My previous correction was wrong about the API host. A live staging smoke test (real bearer key) settled it definitively — there is a spec-host vs API-host split:

• Customer V2 API (what the SDK calls, bearer auth) = api.ade.[env].landing.ai — the AIDE gateway routes the bare /v1/*,/v2/* paths there. This is what V2_ENVIRONMENTS must be.
• V2 spec (codegen/pipeline only) = aide.[env]/openapi.json — but that host's API paths are staff-Google-SSO-gated, so a customer bearer call there fails (GSE 400). api.ade.[env]'s published openapi.json is VTRA's V1/tools spec — which is why the spec must come from aide while the callable endpoint is api.ade. Both are true; don't conflate spec location with API endpoint.

Live proof (staging, real key):

• api.ade.staging.landing.ai → files.upload / extract / extract_jobs / parse / parse_jobs all PASS (5/5, real results).
• aide.staging.landing.ai → all FAIL (Google SSO frontend).

Correct environment matrix

environment	V1 base URL	V2 base URL
production (default)	https://api.va.landing.ai	https://api.ade.landing.ai
eu	https://api.va.eu-west-1.landing.ai	https://api.ade.eu-west-1.landing.ai
staging	https://api.va.staging.landing.ai	https://api.ade.staging.landing.ai
dev	https://api.va.dev.landing.ai	https://api.ade.dev.landing.ai

This is the matrix from the ORIGINAL design doc (I'd wrongly "corrected" it to aide.*). Fixed in PR #105 (_client.py V2_ENVIRONMENTS) and the #96 plan doc. Lesson recorded: verify hosts with a real authenticated call, not unauthenticated probes or spec-location inference.

Also caught live: the /v2/parse/jobs create (202) returns a minimal {"job_id": ...} (no status); the normalizer now defaults status to pending.

[yzld2002]

V2 SDK — non-blocking follow-ups (post-#105)

PR #105 is live-validated (5/5 on staging) and Copilot-clean. The items below were surfaced during the build, the final whole-branch review, and the live smoke test. None block the merge; capturing them here so they aren't lost. Roughly prioritized.

Functional / correctness

1. parse_jobs.create() does not convert a local-path document_url to a file upload. The sync client.v2.parse() calls convert_url_to_file_if_local(...), so parse(document_url="./local.pdf") auto-uploads; parse_jobs.create(document_url="./local.pdf") sends the literal path as a URL (server will reject). One-liner: call the same helper in create(). (Extract has no local-file path param — routes through files.upload → markdown_ref — so it's parse-only.)
2. V2ExtractResult requires extraction/extraction_metadata/markdown/metadata (+ nested metadata.job_id/version/duration_ms). A completed extract job whose result omits any of these raises ValidationError inside extract_jobs.get()/.wait(). V2ParseResponse is fully permissive by contrast. If the gateway can ever return a partial extract result, loosen these to Optional. (Contingent on the real gateway contract.)
3. wait(raise_on_failure=True) keys off job.error is not None, not terminal status. A job that ends failed/cancelled with no error payload returns normally instead of raising. Now documented accurately in api.md, but consider raising on any terminal failed/cancelled regardless of payload.

Polish

4. list(status=...) is typed Optional[str], not Literal[...] on the V2 jobs resources (V1's parse_jobs.list uses a Literal). Tighten in a typed-params pass for autocomplete/typo-catching. No behavior impact.
5. Async waiter sleep isn't parameter-injectable like the sync one (apoll_until_terminal calls anyio.sleep directly; tests monkeypatch it). Fine today; worth harmonizing if wait() ever needs a custom async sleep.
6. Env-var-only ambiguity edge is untested: setting LANDINGAI_ADE_ENVIRONMENT + LANDINGAI_ADE_BASE_URL together trips the existing "Ambiguous URL" error (arguably-correct, but no test).

Deferred by design

7. Client-side markdown/document source-exclusivity is not validated (exactly one of markdown/markdown_ref/markdown_url; and document/document_url). Deferred to the server (422), mirroring V1 client.extract. Fine unless we want earlier/clearer errors.

Spec-sync pipeline (Problem 3), not the V2 SDK

8. surface-lock flags additive public-constant changes as breakages. Adding staging/dev to ENVIRONMENTS tripped it on feat: V2 parse & extract SDK support (client.v2) #105, requiring the breaking-change-approved override label. Refine the gate to ignore attribute-value-only changes (or rename the label to surface-change-approved). Otherwise every future environment addition needs an override.

Release process (not code)

9. Do not cut the production PyPI release until V2 is live at api.ade.landing.ai (prod). The released SDK defaults to production; V2 is currently confirmed only on staging (api.ade.staging). Until prod is live, V2 works via environment="staging". (This is the doc's "production out" gate.)

Items already fixed during review (not follow-ups): None-vs-omit handling, has_more bool coercion, created_at=0, minimal create-envelope status default, unknown-status tolerance, Job.raw default_factory (+ the construct()/_compat fix it exposed), the 504 message, the api.ade.[env] host correction, and docs.
