## Check Results

### API Design

- [pass] Machine-readable, versioned contract — Versioning declared (info.version="1.0.0") and header-versioning detected. Investigated: spec 100%, docs 100%.
- [pass] Auth declared & discoverable — Authentication required (global or on every operation). Investigated: spec 100%, docs 100%.
- [warn] Schema coverage & depth — 0/19 (0%) spec-enum params are realized as constrained types (not bare strings). Investigated: sdk 86%, spec 50%.
- [pass] Security & governance hygiene — No credential-shaped strings detected in spec. Investigated: spec 100%, wellknown 0%.
- [pass] Example coverage — 100% example coverage across params + responses. Investigated: spec 100%, docs 100%, sdk 100%.

### Developer Experience

- [pass] Code samples in docs — Code samples present on 1/20 pages across 2 language(s); broader multi-language coverage missing. Investigated: docs 100%.
- [pass] Description completeness — 85% description completeness (target 90%+). Investigated: spec 100%, sdk 79%.
- [pass] Changelog published — Newest official SDK activity 100 day(s) ago. Investigated: sdk 100%, spec 0%, docs 0%.
- [warn] Quickstart present — Quickstart page reachable (2 variants scanned starting at https://docs.finix.com/api/quickstart) but no runnable code sample detected in HTML or .md variant. Investigated: docs 50%.
- [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%.

### Agent Discovery

- [pass] Registry & SDK presence — Indexed on Context7 (websites/finix, 5303 snippets). Investigated: docs 100%, sdk 100%, cli 0%.
- [warn] Docs reachable, not hard auth-gated — Server ignores Accept: text/markdown header (0/50 sampled pages return markdown). Investigated: docs 75%.
- [warn] llms.txt present, valid & comprehensive — No llms.txt directive found in HTML of any of 50 sampled pages. Investigated: docs 56%, sdk 0%.
- [warn] Crawlable / AEO — Sitemap present (487 entries) but carries no lastmod values. Investigated: wellknown 75%.

### Agent Understanding

- [pass] Machine-readable errors (RFC 9457) — Single base error "OpenApiException" with 11 subclasses. Investigated: sdk 100%, spec 0%, docs 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 — 20 of 50 pages have substantive content differences between markdown and HTML (avg 20% missing). Investigated: docs 80%.
- [fail] Agent instructions file (AGENTS.md) — No AGENTS.md at the site root or /.well-known/. Investigated: wellknown 0%.
- [fail] Docs structured data — Neither JSON-LD nor OpenGraph/meta tags detected across 20 sampled pages — likely a CSR-only docs site. Investigated: docs 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] Sandbox separation — Sandbox server declared but no distinguishable test credentials in scheme descriptions. Investigated: spec 100%, docs 100%, sdk 100%.
- [warn] Runnable collection with test scripts — No test scripts found in the workspace's collections. Investigated: platform 50%.
- [fail] Rate-limit signaling — No rate-limit response headers documented. Investigated: spec 0%, docs 0%.
- [skip] Pagination documented & consistent — No surface produced evidence for this capability in this run.

## Executive Summary

Finix's API design and overall agent discoverability are strong, giving partners a solid technical foundation to build on. However, two gaps stand out as urgent partner-program risks: AI agents and coding assistants lack the structured context files they need to interpret Finix's APIs without guessing, and partners cannot self-serve onboard — both issues slow integration timelines and increase support burden. Closing the agent-context and structured-data gaps first will make Finix's APIs immediately usable by the AI-assisted development workflows partners rely on, while adding a self-service portal removes the final friction point between a partner's first look and their first successful call.
