## Check Results

### API Design

- [pass] Machine-readable, versioned contract — Versioning declared (info.version="1.0.0") and url-versioning detected. Investigated: spec 100%, docs 100%.
- [pass] Auth declared & discoverable — authentication documented in the docs site at https://docs.synthflow.ai/authentication. Investigated: spec 100%, docs 100%.
- [warn] Schema coverage & depth — 93% of operations have documented schemas (target 95%+). Investigated: spec 67%.
- [pass] Security & governance hygiene — No credential-shaped strings detected in spec. Investigated: spec 100%, wellknown 0%.
- [fail] Example coverage — 0% example coverage. Investigated: spec 0%, docs 0%.

### Developer Experience

- [pass] Description completeness — 72% description completeness (target 90%+). Investigated: spec 100%.
- [pass] Changelog published — changelog documented in the docs site at https://docs.synthflow.ai/changelog. Investigated: spec 100%, docs 100%, sdk 50%.
- [warn] Quickstart present — Quickstart page reachable (2 variants scanned starting at https://docs.synthflow.ai/getting-started) 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%.
- [fail] Code samples in docs — No detectable code samples across 20 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%.
- [warn] llms.txt present, valid & comprehensive — llms.txt covers 213/313 sitemap doc pages (68%); 100 missing; 22 llms.txt links not in sitemap (may indicate stale links or incomplete sitemap). Investigated: docs 88%.
- [warn] Registry & SDK presence — Discovered SDKs in only 1 language(s); target ≥3. Investigated: sdk 50%, docs 0%, cli 0%, mcp 0%, wellknown 0%.
- [pass] Crawlable / AEO — Docs paths crawlable by all monitored AI agents. Investigated: wellknown 100%.

### Agent Understanding

- [pass] Machine-readable errors (RFC 9457) — 8 distinct 4xx/5xx response codes documented. Investigated: docs 100%, spec 50%.
- [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 — 7 of 50 pages have substantive content differences between markdown and HTML (avg 11% missing). Investigated: docs 70%.
- [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 3 assessed pages (3 JS-rendered). 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

- [fail] Idempotency documented — 0% of mutating operations document idempotency. Investigated: spec 0%, docs 0%.
- [fail] Rate-limit signaling — No rate-limit response headers documented. Investigated: spec 0%, docs 0%.
- [fail] Sandbox separation — No sandbox/test server declared across 3 server entries; no test-key prefixes documented. Investigated: spec 0%, docs 0%.
- [fail] Runnable collection with test scripts — No public Postman workspace discovered for the org. Investigated: platform 0%.
- [skip] Pagination documented & consistent — No surface produced evidence for this capability in this run.

## Executive Summary

Synthflow's API program shows real strength in discoverability and schema design — partners and agents can find and parse the surface. The two areas that need urgent attention are agent usability and developer experience: without sandbox separation, idempotency guidance, rate-limit signaling, or a runnable collection, neither human partners nor AI agents can safely run real workflows — and without a self-service portal and inline code samples, partners simply can't get started without friction. Prioritizing operational reliability and onboarding infrastructure will unlock partner self-sufficiency at scale.
