## 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] Schema coverage & depth — 2331/2333 (100%) public params are fully typed (no any/**kwargs). Analyzer reports not all methods have a derivable input schema. Investigated: sdk 100%, spec 50%.
- [pass] Security & governance hygiene — No credential-shaped strings detected in spec. Investigated: spec 100%, wellknown 0%.
- [pass] Example coverage — Code samples present on 2/10 pages across 1 language(s); broader multi-language coverage missing. Investigated: docs 100%, sdk 100%, spec 0%.

### Developer Experience

- [pass] Code samples in docs — Code samples present on 2/10 pages across 1 language(s); broader multi-language coverage missing. Investigated: docs 100%.
- [pass] Description completeness — 89% description completeness (target 90%+). Investigated: spec 100%, sdk 87%.

- [pass] Registry & SDK presence — Indexed on Context7 (websites/extend_ai, 2625 snippets). Investigated: docs 100%, sdk 100%, cli 100%.
- [warn] llms.txt present, valid & comprehensive — llms.txt covers 0/1 sitemap doc pages (0%); 1 missing. Investigated: docs 75%, sdk 0%.
- [warn] Crawlable / AEO — Sitemap lastmod coverage 28% or newest entry older than 90 days. Investigated: wellknown 75%.

### Agent Understanding

- [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 1 assessed pages (1 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

- [pass] Idempotency documented — Built-in retry machinery is present (grep-derived). 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

Extend's API program has strong fundamentals in schema design and agent discoverability, but two areas are holding back partner outcomes: developer onboarding and agent-readiness. Partners currently lack a self-service portal and quickstart path, meaning every new integration requires manual intervention rather than autonomous evaluation and activation. At the same time, the absence of agent-oriented context files, structured documentation data, and runnable collections means AI agents your partners rely on cannot reliably parse, understand, or execute against your API — slowing integrations and increasing support burden. Prioritize building a self-service, agent-ready documentation experience first, then layer in runnable collections and operational completeness to unlock fully autonomous partner workflows.
