The Anything API's v1 backend (SSE event feed) is retired: prod reached zero v1 threads on 2026-08-28 and POST /api/anything/start now speaks only v2 (nottelabs/anything-api#544). This updates docs.notte.cc to match.

Changes

  • product/anything-api.mdx rewritten to the v2 contract: request fields (query, thread_id follow-ups, detach, model, reasoningEffort, version defaulting "v2"), the streamed response (AI SDK UI message stream, useChat-compatible, x-thread-id header), detached mode (202 {thread_id, url, status: "started"}), and a "Migrating from v1" warning (explicit version:"v1"400 unsupported_version; the AI SDK stream replaces the SSE event feed; resume_strategy/snapshots/claude_code_session_id are gone).
  • Snippet pipeline followed: consume_sse.py replaced by consume_stream.py + start_detached.py, snippets regenerated with sniptest/generate.py --clean.

Flagged for reviewer

  • The API-reference tab and llms.txt derive from the remote api.notte.cc/openapi.json — if that spec still describes v1 for anything-start, it needs a server-side update this PR can't make.
  • The old Pricing section (keyed to the v1 done event's total_cost_usd) and the 502 SSE stream unavailable error row were dropped without v2 replacements — if v2 surfaces cost or the deployed function_id in its stream, those could be documented in a follow-up.

Checks

mintlify broken-links clean, verify_all_mdx.py all match, check_docs_nav.py exit 0, pre-commit hooks (ruff, snippet verification, nav) all passed. New testers are typecheck_only and pass ruff + compile.

Merge together with nottelabs/anything-api#544 (the docs describe the post-#544 behavior).

The v1 backend (SSE event feed) is retired. Rewrite the Anything API
page around the v2 POST /api/anything/start contract:

- responses stream as an AI SDK UI message stream (useChat-compatible,
  x-vercel-ai-ui-message-stream: v1) with an x-thread-id header
- detach: true returns 202 {thread_id, url, status: "started"}
- thread_id sends follow-up turns into an existing thread
- version defaults to v2; explicit v1 now returns 400 unsupported_version
- drop v1-only docs: SSE event table, resume_strategy, snapshots,
  claude_code_session_id; add a migration note for former v1 callers

Replace the consume_sse tester/snippet with consume_stream and add a
start_detached tester/snippet (both typecheck-only).

Walkthrough

The Anything API documentation now describes the v2 contract. It documents streamed UI messages, thread headers, new request parameters, detached execution, follow-up turns, and v1 migration behavior. The TypeScript example parses [DONE] and JSON chunks. New Python snippets and tester scripts cover streamed and detached requests. The previous SSE consumption examples were removed.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟠 High · up to 2f6d2

The updated documentation could expose server API credentials when used directly from browser clients, and its stream example may fail on normal CRLF-formatted termination frames. These are concrete security and correctness issues that should be fixed before merging.

Greptile Summary

The PR updates the Anything API documentation and generated examples from the retired v1 SSE contract to the v2 AI SDK stream contract.

  • Documents streamed and detached execution, thread-based follow-ups, request fields, response headers, and v1 migration behavior.
  • Replaces the SSE consumer with Python stream-consumption and detached-start examples.

Confidence Score: 5/5

The PR appears safe to merge because no blocking failure remains within the scope of this follow-up review.

No blocking failure remains.

Important Files Changed

Filename Overview
docs/src/product/anything-api.mdx Rewrites the product documentation around the v2 streaming, detached execution, follow-up, and migration contracts without an eligible follow-up finding.

docs/src/testers/anything-api/start_detached.py Adds the typecheck-only source for the generated detached-run example.

163-172: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Terminate the outer stream loop and normalize CRLF frames.

break exits only the inner for loop, so the outer loop calls reader.read() again after [DONE]. With CRLF frames, payload is [DONE]\r; the sentinel does not match, and JSON.parse throws. Track stream termination and remove the trailing \r before parsing.

Re: the typecheck_only finding — intentional, matching repo convention rather than an omission. Seven existing testers (Steel, captcha, tailnet, hermes) are typecheck_only because executing them needs paid external services, and the pre-existing anything-api tester run_function.py is typecheck_only for the same reason. Executing these two would run a real, billed Anything API agent build (2–10 minutes) on every docs CI run. The examples pass ruff + typecheck, and the wire format they parse (AI SDK UI message stream, data: {...} / data: [DONE]) is covered by the proxy contract tests in nottelabs/monorepo#2395.
