## Check Results

### API Design

- [warn] Security & governance hygiene — security.txt present but missing Contact; missing or expired Expires. Investigated: wellknown 50%.
- [fail] Example coverage — No detectable code samples across 1 sampled docs pages. Investigated: docs 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] Self-service developer portal — Self-service signup at https://store.steampowered.com/join; no free tier or sandbox language detected. Investigated: docs 100%.
- [warn] Quickstart present — Quickstart page reachable (24 variants scanned starting at https://partner.steamgames.com/doc/home) but no runnable code sample detected in HTML or .md variant. Investigated: docs 50%.
- [fail] Code samples in docs — No detectable code samples across 1 sampled docs pages. Investigated: docs 0%.
- [skip] Description completeness — No surface produced evidence for this capability in this run.
- [skip] Changelog published — No surface produced evidence for this capability in this run.

### Agent Discovery

- [pass] Registry & SDK presence — Indexed on Context7 (steampoweredtaco/gotiktoklive, 63 snippets). Investigated: docs 100%, sdk 0%, cli 0%.
- [warn] llms.txt present, valid & comprehensive — No llms.txt found at any candidate location (https://partner.steamgames.com/doc/webapi/llms.txt, https://partner.steamgames.com/llms.txt, https://partner.steamgames.com/docs/llms.txt). Investigated: docs 33%.
- [warn] Crawlable / AEO — Sitemap present (0 entries) but carries no lastmod values. Investigated: wellknown 75%.
- [warn] Docs reachable, not hard auth-gated — 1 of 1 pages return 200 for non-existent URLs (soft 404). Investigated: docs 25%.

### Agent Understanding

- [warn] Agent-navigable, token-efficient docs — No pages support .md URLs (0/1 tested). Investigated: docs 71%.
- [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 sampled pages — likely a CSR-only docs site. 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 0 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

Steampowered's API program shows strength in crawlability and broad discoverability, but is meaningfully held back in two areas that directly affect partner and agent success: the API contract lacks concrete examples, and the documentation is missing the machine-readable signals that AI agents rely on to understand, parse, and execute against your APIs. Fixing example coverage and agent-facing context first will unlock faster partner integration and make your APIs usable by the AI-powered tools partners increasingly depend on.
