## Check Results

### API Design

- [pass] Auth declared & discoverable — Authentication required (global or on every operation). Investigated: spec 100%, docs 100%.
- [pass] Schema coverage & depth — 195/196 (99%) public params are fully typed (no any/**kwargs). Analyzer reports not all methods have a derivable input schema. Investigated: sdk 100%, spec 83%.
- [warn] Machine-readable, versioned contract — info.version="2.0.0" 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 50%.
- [pass] Example coverage — 23% example coverage. Investigated: spec 100%, sdk 100%, docs 0%.

### Developer Experience

- [pass] Self-service developer portal — Signup page at https://www.coinbase.com/dashboard/signup (CSR-rendered — body classifier inconclusive); free tier / sandbox documented in pricing/docs. Investigated: docs 100%.
- [pass] Description completeness — 88% description completeness (target 90%+). Investigated: spec 100%, sdk 93%.
- [pass] Changelog published — changelog documented in the docs site at https://docs.cdp.coinbase.com/get-started/changelog. Investigated: spec 100%, docs 100%, sdk 100%.
- [warn] Quickstart present — Quickstart page reachable (1 variants scanned starting at https://docs.cdp.coinbase.com/get-started/overview) but no runnable code sample detected in HTML or .md variant. Investigated: docs 50%.
- [fail] Code samples in docs — No detectable code samples across 20 sampled docs pages. Investigated: docs 0%.

### Agent Discovery

- [pass] Registry & SDK presence — Indexed on Context7 (tiagosiebler/coinbase-api, 1166 snippets). Investigated: docs 100%, sdk 100%, cli 0%, mcp 0%, wellknown 0%.
- [warn] Docs reachable, not hard auth-gated — 2 of 50 pages use cross-host redirects. Investigated: docs 88%.
- [warn] llms.txt present, valid & comprehensive — llms.txt covers 42/2347 sitemap doc pages (2%); 2305 missing; 8 llms.txt links not in sitemap (may indicate stale links or incomplete sitemap). 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) — No explicit 4xx/5xx codes, but 29 operation(s) document a "default" error response. Investigated: docs 100%, sdk 100%, spec 50%.
- [pass] Operation purpose clarity — 99% of operations have a clear summary + operationId an agent can select on. Investigated: spec 100%.
- [warn] Agent-navigable, token-efficient docs — 1 of 1 page(s) with tab headers don't distinguish between variants. Investigated: docs 70%.
- [pass] Docs structured data — JSON-LD Article markup on 14/14 assessed pages (100%) with dateModified present. Investigated: docs 100%.
- [warn] Description consistency across surfaces — Mean pairwise description similarity across 2 surfaces (spec, sdk) is 4% (threshold 35% for full credit).
- [fail] Agent instructions file (AGENTS.md) — No AGENTS.md at the site root or /.well-known/. Investigated: wellknown 0%.

### Agent Usability

- [pass] Idempotency documented — 76% of mutating operations document idempotency. Investigated: spec 100%, docs 100%, sdk 100%.
- [pass] Rate-limit signaling — rate-limit behavior documented in the docs site at https://docs.cdp.coinbase.com/api-reference/v2/rate-limits. Investigated: spec 100%, docs 100%.
- [pass] Pagination documented & consistent — Pagination params detected on 1 list endpoint(s). Investigated: spec 100%, docs 100%.
- [pass] Sandbox separation — Sandbox environments are exposed (sandbox). Investigated: sdk 100%, spec 0%, docs 0%.
- [fail] Runnable collection with test scripts — No public Postman workspace discovered for the org. Investigated: platform 0%.

## Executive Summary

Coinbase's API program is strong overall — contract quality, schema design, and discoverability are all in excellent shape. The two areas that most directly block partner and agent success today are the absence of an agent instructions file that orients AI agents to your API surface, and the lack of a runnable, test-backed collection that gives both partners and their coding agents verified, executable examples to build against. Closing these two gaps will dramatically shorten the time partners spend guessing at integration patterns and reduce the risk of agents hallucinating incorrect usage — prioritize them in that order.
