## Check Results

### API Design

- [pass] Auth declared & discoverable — Authentication required (global or on every operation). Investigated: spec 100%, docs 100%.
- [warn] Schema coverage & depth — 667/669 (100%) public params are fully typed (no any/**kwargs). Analyzer reports not all methods have a derivable input schema. Investigated: sdk 100%, spec 67%.
- [warn] Machine-readable, versioned contract — info.version="v1" set but no versioning scheme (URL / header / media type) detected. Investigated: spec 75%, docs 50%.
- [pass] Security & governance hygiene — No credential-shaped strings detected in spec. Investigated: spec 100%, wellknown 100%.
- [pass] Example coverage — Code samples present on 2/20 pages across 1 language(s); broader multi-language coverage missing. Investigated: docs 100%, sdk 100%, spec 0%.

### Developer Experience

- [pass] Self-service developer portal — Self-service signup at https://www.browserbase.com/sign-up; free tier / sandbox documented. Investigated: docs 100%.
- [pass] Quickstart present — Quickstart at https://docs.browserbase.com/welcome/getting-started with a runnable first-call sample. Investigated: docs 100%.
- [pass] Code samples in docs — Code samples present on 2/20 pages across 1 language(s); broader multi-language coverage missing. Investigated: docs 100%.
- [pass] Changelog published — changelog documented in the docs site at https://www.browserbase.com/changelog. Investigated: spec 100%, docs 100%, sdk 100%.
- [warn] Description completeness — 152/314 operations lack a description. Investigated: sdk 52%, spec 0%.

### Agent Discovery

- [pass] llms.txt present, valid & comprehensive — llms.txt found at https://docs.browserbase.com/llms.txt. Investigated: docs 100%, sdk 0%.
- [pass] Docs reachable, not hard auth-gated — All 1 pages are publicly accessible. Investigated: docs 100%.
- [pass] Registry & SDK presence — Indexed on Context7 (websites/browserbase, 1831 snippets). Investigated: docs 100%, sdk 67%, cli 0%.
- [pass] Crawlable / AEO — Docs paths crawlable by all monitored AI agents. Investigated: wellknown 100%.

### Agent Understanding

- [pass] Machine-readable errors (RFC 9457) — 11 distinct 4xx/5xx response codes documented. Investigated: docs 100%, sdk 100%, spec 50%.
- [pass] Operation purpose clarity — 96% of operations have a clear summary + operationId an agent can select on. Investigated: spec 100%.
- [pass] Agent-navigable, token-efficient docs — All 1 pages contain server-rendered content. Investigated: docs 100%.
- [pass] Docs structured data — JSON-LD Article markup on 18/18 assessed pages (100%) with dateModified present. Investigated: docs 100%.
- [fail] Agent instructions file (AGENTS.md) — No AGENTS.md at the site root or /.well-known/. Investigated: wellknown 0%.
- [skip] Description consistency across surfaces — Only 1 surface description(s) with ≥6 tokens available; need at least 2 to compare.

### Agent Usability

- [pass] Idempotency documented — Built-in retry machinery is present (grep-derived). Investigated: sdk 100%, spec 0%, docs 0%.
- [pass] Pagination documented & consistent — Pagination params detected on 12 list endpoint(s). Investigated: spec 100%, docs 100%, sdk 0%.
- [pass] Sandbox separation — Sandbox environments are exposed (sandbox). Investigated: sdk 100%, spec 0%, docs 0%.
- [fail] Rate-limit signaling — No rate-limit response headers documented. Investigated: spec 0%, docs 0%.
- [fail] Runnable collection with test scripts — No public Postman workspace discovered for the org. Investigated: platform 0%.

## Executive Summary

Browserbase's API program has strong fundamentals — the contract is machine-readable, schemas are well-typed, and description quality is solid — giving partners a reliable surface to build against. The two areas that most limit partner and agent success are the absence of agent-specific context files (meaning AI coding agents lack the structured guidance to use the API correctly without guessing) and the lack of a runnable, test-backed collection (meaning partners have no executable starting point to validate their integration end-to-end). Prioritizing these two gaps will dramatically shorten the path from discovery to a working integration for both human partners and the AI agents they rely on.
