## Check Results

### API Design

- [pass] Auth declared & discoverable — Authentication required (global or on every operation). Investigated: spec 100%, docs 100%.
- [pass] Schema coverage & depth — 4036/4041 (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="1.0.0" 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 — Code samples in 3 language(s) across docs (top: shell, typescript, http); 1/20 pages have ≥ 2 languages on the same page. Investigated: docs 100%, sdk 100%, spec 0%.

### Developer Experience

- [pass] Self-service developer portal — Signup page at https://app.lithic.com/signup (CSR-rendered — body classifier inconclusive); free tier / sandbox documented in pricing/docs. Investigated: docs 100%.
- [pass] Quickstart present — Quickstart at https://docs.lithic.com/docs/create-card with a runnable first-call sample. Investigated: docs 100%.
- [pass] Code samples in docs — Code samples in 3 language(s) across docs (top: shell, typescript, http); 1/20 pages have ≥ 2 languages on the same page. Investigated: docs 100%.
- [pass] Description completeness — 79% description completeness (target 90%+). Investigated: spec 100%, sdk 94%.
- [pass] Changelog published — changelog documented in the docs site at https://docs.lithic.com/changelog. Investigated: spec 100%, docs 100%, sdk 100%.

### Agent Discovery

- [pass] Registry & SDK presence — Indexed on Context7 (lithic-com/lithic-node, 367 snippets). Investigated: docs 100%, sdk 92%, cli 0%.
- [pass] Crawlable / AEO — Docs paths crawlable by all monitored AI agents. Investigated: wellknown 100%.
- [fail] llms.txt present, valid & comprehensive — No /llms-full.txt found at the candidate origins. Investigated: docs 0%, sdk 0%.
- [skip] Docs reachable, not hard auth-gated — No surface produced evidence for this capability in this run.

### Agent Understanding

- [pass] Machine-readable errors (RFC 9457) — 10 distinct 4xx/5xx response codes documented. Investigated: docs 100%, sdk 100%, spec 50%.
- [pass] Operation purpose clarity — 97% of operations have a clear summary + operationId an agent can select on. Investigated: spec 100%.
- [pass] Docs structured data — JSON-LD Article markup on 20/20 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] Agent-navigable, token-efficient docs — No surface produced evidence for this capability in this run.
- [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 50 list endpoint(s). Investigated: spec 100%, docs 100%, sdk 98%.
- [pass] Sandbox separation — Sandbox server declared but no distinguishable test credentials in scheme descriptions. Investigated: spec 100%, docs 100%, sdk 100%.
- [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

Lithic's API design and overall documentation quality are strong foundations for a partner program — the machine-readable contract and schema coverage are excellent. However, two areas demand immediate attention: agents and partners cannot discover or orient themselves to Lithic's APIs without manual guidance, and there is no runnable, test-backed collection for partners to validate integrations quickly. Prioritizing discoverability infrastructure (llms.txt, agent instruction files) and executable onboarding artifacts will unlock self-serve partner adoption and ensure AI coding agents can integrate reliably without guesswork.
