## Check Results

### API Design

- [warn] Machine-readable, versioned contract — `--help --format json` exits 0 but output is not JSON. Investigated: cli 75%.
- [pass] Security & governance hygiene — security.txt valid at https://elevenlabs.io/.well-known/security.txt (Contact + unexpired Expires). Investigated: wellknown 100%.
- [warn] Auth declared & discoverable — help mentions auth but not the exact env var. Investigated: cli 50%.
- [pass] Example coverage — Code samples present on 1/20 pages across 1 language(s); broader multi-language coverage missing. Investigated: docs 100%, cli 100%.
- [skip] Schema coverage & depth — No surface produced evidence for this capability in this run.

### Developer Experience

- [pass] Self-service developer portal — Signup page at https://elevenlabs.io/app/sign-up; no free-tier language detected in docs/pricing. Investigated: docs 100%.
- [pass] Quickstart present — Quickstart at https://elevenlabs.io/docs/eleven-api/quickstart has a runnable sample in the .md variant (https://elevenlabs.io/docs/eleven-api/quickstart.md). Investigated: docs 100%.
- [pass] Code samples in docs — Code samples present on 1/20 pages across 1 language(s); broader multi-language coverage missing. Investigated: docs 100%.
- [pass] Changelog published — Newest official SDK activity 0 day(s) ago. Investigated: sdk 100%.
- [skip] Description completeness — No surface produced evidence for this capability in this run.

### Agent Discovery

- [pass] llms.txt present, valid & comprehensive — llms-full.txt reachable at https://elevenlabs.io/docs/overview/intro/llms-full.txt. Investigated: docs 100%.
- [pass] Registry & SDK presence — Indexed on Context7 (websites/elevenlabs_io, 5712 snippets). Investigated: docs 100%, sdk 100%, cli 100%.
- [warn] Crawlable / AEO — Sitemap present (277 entries) but carries no lastmod values. Investigated: wellknown 75%.
- [skip] Docs reachable, not hard auth-gated — No surface produced evidence for this capability in this run.

### Agent Understanding

- [fail] Machine-readable errors (RFC 9457) — errors are prose, not a structured envelope. Investigated: cli 0%.
- [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 10 assessed pages (2 JS-rendered). Investigated: docs 0%.
- [skip] Operation purpose clarity — No surface produced evidence for this capability in this run.
- [skip] Agent-navigable, token-efficient docs — 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] Idempotency documented — no `--dry-run` flag found. Investigated: cli 0%.
- [fail] Runnable collection with test scripts — No public Postman workspace discovered for the org. Investigated: platform 0%.
- [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

ElevenLabs' API discovery is a genuine strength — partners and agents can find your APIs without friction. However, the program has two critical gaps that will stall partner integrations and undermine AI agent reliability: agents and developers cannot parse or act on errors (no machine-readable error bodies), and there is no runnable, testable context for agents to build against confidently. Prioritize making errors actionable and adding executable, test-backed collections first, then close the remaining context and documentation gaps to unlock self-serve partner success at scale.
