## Check Results

### API Design

- [pass] Machine-readable, versioned contract — Versioning declared (info.version="1.0") and url-versioning detected. Investigated: spec 100%, docs 100%.
- [pass] Schema coverage & depth — 40/40 (100%) public params are fully typed (no any/**kwargs). Analyzer confirms all methods have a derivable input schema. Investigated: sdk 100%, spec 67%.
- [pass] Auth declared & discoverable — Authentication required (global or on every operation). Investigated: spec 100%, docs 100%.
- [pass] Security & governance hygiene — No credential-shaped strings detected in spec. Investigated: spec 100%, wellknown 0%.
- [pass] Example coverage — 61% example coverage (target 80%+). Investigated: spec 100%, sdk 100%.

### Developer Experience

- [pass] Description completeness — 100% of operations + parameters have substantive descriptions. Investigated: spec 100%, sdk 98%.
- [pass] Changelog published — Newest official SDK activity 3 day(s) ago. Investigated: sdk 100%, spec 0%, docs 0%.
- [fail] Self-service developer portal — Signup page is sales-gated (contact-sales/request-access language detected). Investigated: docs 0%.
- [fail] Quickstart present — No quickstart/getting-started page found at the conventional paths. Investigated: docs 0%.
- [skip] Code samples in docs — No surface produced evidence for this capability in this run.

### Agent Discovery

- [pass] Registry & SDK presence — Indexed on Context7 (apolloconfig/apollo, 1322 snippets). Investigated: docs 100%, sdk 58%, cli 0%, mcp 0%, wellknown 0%.
- [warn] llms.txt present, valid & comprehensive — No /llms-full.txt found at the candidate origins. Investigated: docs 79%, sdk 0%.
- [warn] Docs reachable, not hard auth-gated — 50 JavaScript redirect(s) detected across 50 sampled pages. Investigated: docs 50%.
- [warn] Crawlable / AEO — No sitemap discoverable via robots.txt or /sitemap.xml on the docs host. Investigated: wellknown 50%.

### Agent Understanding

- [pass] Machine-readable errors (RFC 9457) — 8 distinct 4xx/5xx response codes documented. Investigated: docs 100%, spec 50%, sdk 0%.
- [pass] Operation purpose clarity — 99% of operations have a clear summary + operationId an agent can select on. Investigated: spec 100%.
- [warn] Agent-navigable, token-efficient docs — No sampled pages support .md URLs (0/50 tested). Investigated: docs 69%.
- [warn] Description consistency across surfaces — Mean pairwise description similarity across 2 surfaces (spec, sdk) is 4% (threshold 35% for full credit).
- [fail] Agent instructions file (AGENTS.md) — No AGENTS.md at the site root or /.well-known/. Investigated: wellknown 0%.
- [skip] Docs structured data — No surface produced evidence for this capability in this run.

### Agent Usability

- [pass] Idempotency documented — Built-in retry machinery is present (grep-derived). Investigated: sdk 100%, spec 0%, docs 0%.
- [pass] Sandbox separation — Sandbox environments are exposed (sandbox). Investigated: sdk 100%, spec 0%, docs 0%.
- [fail] Rate-limit signaling — No rate-limit response headers documented. Investigated: spec 0%, docs 0%.
- [fail] Pagination documented & consistent — 1 list endpoint(s) exist but no pagination params found. Investigated: spec 0%, docs 0%.
- [fail] Runnable collection with test scripts — No public Postman workspace discovered for the org. Investigated: platform 0%.

## Executive Summary

Apollo's API program shows genuine strength in documentation discovery and crawlability, meaning agents and partners can find the front door. However, two areas are holding back partner activation: there is no self-service portal or quickstart to get partners to a first successful call without friction, and there are no runnable collections or agent instruction files to give partners and their AI agents the executable context they need to integrate correctly. Closing these gaps will accelerate partner onboarding, reduce integration guesswork, and make Apollo's APIs actionable for the AI-powered tools partners already use.
