## Check Results

### API Design

- [pass] Auth declared & discoverable — Authentication required (global or on every operation). Investigated: spec 100%, docs 100%.
- [warn] Schema coverage & depth — 381/383 (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="0.2.0" 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] Quickstart present — Quickstart at https://inference-docs.cerebras.ai/quickstart with a runnable first-call sample. Investigated: docs 100%.
- [pass] Description completeness — 24% description completeness. Investigated: spec 100%, sdk 36%.
- [pass] Changelog published — Newest official SDK activity 7 day(s) ago. Investigated: sdk 100%, spec 0%, docs 0%.
- [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] 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 (websites/inference-docs_cerebras_ai, 2808 snippets). Investigated: docs 100%, cli 100%, sdk 67%.
- [warn] llms.txt present, valid & comprehensive — llms.txt contains parseable links but doesn't fully follow the proposed structure: https://inference-docs.cerebras.ai/llms.txt: No blockquote summary found. Investigated: docs 88%, sdk 0%.
- [warn] Docs reachable, not hard auth-gated — 2 of 50 sampled pages use cross-host redirects. Investigated: docs 88%.
- [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://inference-docs.cerebras.ai/support/error. Investigated: docs 100%, sdk 100%, spec 50%.
- [warn] Operation purpose clarity — 71% of operations are agent-inferable (target 90%+). Investigated: spec 75%.
- [warn] Agent-navigable, token-efficient docs — 3 of 47 pages have substantive content differences between markdown and HTML (avg 5% missing). Investigated: docs 72%.
- [pass] Docs structured data — JSON-LD Article markup on 20/20 assessed pages (100%) with dateModified present. Investigated: docs 100%.
- [warn] Description consistency across surfaces — Mean pairwise description similarity across 2 surfaces (docs, sdk) is 7% (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 — Built-in retry machinery is present (grep-derived). Investigated: sdk 100%, spec 0%, docs 0%.
- [pass] Rate-limit signaling — rate-limit behavior documented in the docs site at https://inference-docs.cerebras.ai/console/usage-monitoring. Investigated: spec 100%, docs 100%.
- [pass] Sandbox separation — Sandbox environments are exposed (sandbox). Investigated: sdk 100%, spec 0%, docs 0%.
- [fail] Pagination documented & consistent — None of the 9 measured list method(s) return an auto-paginating iterable. Investigated: sdk 0%.
- [fail] Runnable collection with test scripts — No public Postman workspace discovered for the org. Investigated: platform 0%.

## Executive Summary

Cerebras's API program shows genuine strengths in API design, discovery, and documentation reachability — partners and agents can find and read the contract reliably. The two areas that most limit partner success right now are agent understanding and developer onboarding: there is no agent instructions file to orient AI coding tools, no runnable collection for partners to make a first call, and no self-service portal with embedded code samples. Fixing these gaps will compress time-to-first-integration for both human partners and the AI agents they use, and dramatically reduce the hand-holding your partner team currently absorbs.
