## Check Results

### API Design

- [pass] Example coverage — Code samples in 8 language(s) across docs (top: php, shell, csharp); 3/20 pages have ≥ 2 languages on the same page. Investigated: docs 100%.
- [fail] Security & governance hygiene — No security.txt at /.well-known/security.txt or /security.txt. Investigated: wellknown 0%.
- [skip] Machine-readable, versioned contract — No surface produced evidence for this capability in this run.
- [skip] Schema coverage & depth — No surface produced evidence for this capability in this run.
- [skip] Auth declared & discoverable — No surface produced evidence for this capability in this run.

### Developer Experience

- [pass] Code samples in docs — Code samples in 8 language(s) across docs (top: php, shell, csharp); 3/20 pages have ≥ 2 languages on the same page. Investigated: docs 100%.
- [pass] Changelog published — Newest official SDK activity 16 day(s) ago. Investigated: sdk 100%.
- [warn] Quickstart present — Quickstart page reachable (1 variants scanned starting at https://hightouch.com/docs/syncs/create-your-first-sync) 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%.
- [skip] Description completeness — No surface produced evidence for this capability in this run.

### Agent Discovery

- [pass] Registry & SDK presence — Indexed on Context7 (websites/hightouch, 13922 snippets). Investigated: docs 100%, cli 100%, sdk 50%, mcp 0%, wellknown 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 63%.
- [warn] Crawlable / AEO — Sitemap present (3 entries) but carries no lastmod values. Investigated: wellknown 75%.

### Agent Understanding

- [warn] Agent-navigable, token-efficient docs — No sampled pages support .md URLs (0/50 tested). Investigated: docs 64%.
- [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 4 assessed pages (3 JS-rendered). Investigated: docs 0%.
- [skip] Machine-readable errors (RFC 9457) — No surface produced evidence for this capability in this run.
- [skip] Operation purpose clarity — 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

- [fail] Runnable collection with test scripts — No public Postman workspace discovered for the org. Investigated: platform 0%.
- [skip] Idempotency documented — No surface produced evidence for this capability in this run.
- [skip] Rate-limit signaling — No surface produced evidence for this capability in this run.
- [skip] Pagination documented & consistent — No surface produced evidence for this capability in this run.
- [skip] Sandbox separation — No surface produced evidence for this capability in this run.

## Executive Summary

Hightouch's API program shows strong discoverability fundamentals, but partners and their AI agents face real friction in three critical areas: the API contract lacks security and governance hygiene that enterprise partners require before committing to an integration; there is no runnable, tested collection giving agents the concrete request/response shapes they need to integrate correctly; and the documentation lacks the machine-readable signals (structured data, agent instruction files) that AI agents depend on to parse and act on your APIs without guessing. Prioritize closing the security contract and runnable truth gaps first — these block partner confidence and agent-driven integration alike — then layer in the agent-readiness enhancements to make your docs a fully autonomous-friendly front door.
