## Check Results

### API Design

- [pass] Auth declared & discoverable — Authentication required (global or on every operation). Investigated: spec 100%, docs 100%.
- [warn] Schema coverage & depth — 6 of 278 public signatures use loose types (anyTypeRatio=0.022). Investigated: sdk 91%, spec 75%.
- [warn] Machine-readable, versioned contract — info.version="0" 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 0%.
- [pass] Example coverage — README is present and includes a runnable quickstart. Investigated: sdk 100%, spec 0%, docs 0%.

### Developer Experience

- [pass] Description completeness — 84% description completeness (target 90%+). Investigated: spec 100%, sdk 94%.
- [pass] Changelog published — changelog documented in the docs site at https://exa.ai/docs/changelog. Investigated: spec 100%, docs 100%, sdk 100%.
- [fail] Self-service developer portal — No signup page detected across conventional paths (/signup, /sign-up, /register, /get-started, /console/signup, /dashboard/signup, /try, /try-free, /free, /free-trial, /start, /start-free). Investigated: docs 0%.
- [fail] Quickstart present — No quickstart/getting-started page found at the conventional paths. Investigated: docs 0%.
- [fail] Code samples in docs — No detectable code samples across 1 sampled docs pages. Investigated: docs 0%.

### Agent Discovery

- [pass] Docs reachable, not hard auth-gated — All 50 sampled pages are publicly accessible. Investigated: docs 100%.
- [pass] Registry & SDK presence — Indexed on Context7 (websites/exa_ai, 990 snippets). Investigated: docs 100%, sdk 100%, cli 0%.
- [warn] llms.txt present, valid & comprehensive — llms.txt found but only reachable via cross-host redirect (agents may not follow it). Investigated: docs 81%, sdk 0%.
- [pass] Crawlable / AEO — Docs paths crawlable by all monitored AI agents. Investigated: wellknown 100%.

### Agent Understanding

- [pass] Machine-readable errors (RFC 9457) — error codes documented in the docs site at https://exa.ai/docs/reference/error-codes. Investigated: docs 100%, spec 50%, sdk 0%.
- [pass] Operation purpose clarity — 100% of operations have a clear summary + operationId an agent can select on. Investigated: spec 100%.
- [warn] Agent-navigable, token-efficient docs — 3 of 48 pages have substantive content differences between markdown and HTML (avg 3% missing). Investigated: docs 72%.

- [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] Rate-limit signaling — rate-limit behavior documented in the docs site at https://exa.ai/docs/reference/rate-limits. Investigated: spec 100%, docs 100%.
- [pass] Sandbox separation — Sandbox environments are exposed (sandbox). Investigated: sdk 100%, spec 0%, docs 0%.
- [warn] Pagination documented & consistent — Only 1/11 list method(s) return an auto-paginating iterable; 10 return a raw page. Investigated: sdk 9%.
- [fail] Idempotency documented — 0% of mutating operations document idempotency. Investigated: spec 0%, docs 0%, sdk 0%.
- [fail] Runnable collection with test scripts — No public Postman workspace discovered for the org. Investigated: platform 0%.

## Executive Summary

Exa's API design and discovery foundations are strong — partners and agents can find and read the contract without friction. The critical gaps are in onboarding and agent-readiness: there is no self-service portal, no quickstart, and no runnable collection, meaning a partner today cannot make a first call without significant manual effort, and AI agents lack the executable context and instructions they need to integrate correctly. Closing the onboarding and agent-usability gaps should be the immediate priority to unlock self-serve partner growth and reliable agent-driven integrations.
