## Check Results

### API Design

- [pass] Machine-readable, versioned contract — OpenAPI 3.0.1 declared (3.0.x; 3.1 adds JSON Schema 2020-12 alignment but is not required for full credit). Investigated: spec 100%, docs 100%.
- [pass] Schema coverage & depth — 2/2 enums are named types (not bare strings). Investigated: sdk 100%, spec 61%.
- [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 — Code samples present on 6/20 pages across 1 language(s); broader multi-language coverage missing. Investigated: docs 100%, sdk 100%, spec 0%.

### Developer Experience

- [pass] Quickstart present — Quickstart at https://docs.commercelayer.io/core has a runnable sample in the .md variant (https://docs.commercelayer.io/core.md). Investigated: docs 100%.
- [pass] Code samples in docs — Code samples present on 6/20 pages across 1 language(s); broader multi-language coverage missing. Investigated: docs 100%.
- [pass] Description completeness — 74% description completeness (target 90%+). Investigated: spec 100%.
- [pass] Changelog published — changelog documented in the docs site at https://docs.commercelayer.io/changelog/archive/2025. Investigated: spec 100%, docs 100%, sdk 100%.
- [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%.

### Agent Discovery

- [pass] llms.txt present, valid & comprehensive — llms-full.txt reachable at https://docs.commercelayer.io/llms-full.txt. Investigated: docs 100%, sdk 0%.
- [pass] Registry & SDK presence — Official CLI at commercelayer/commercelayer-cli with published releases (installable). Investigated: cli 100%, sdk 50%, docs 0%, mcp 0%, wellknown 0%.
- [warn] Crawlable / AEO — Sitemap present (11 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

- [pass] Operation purpose clarity — 100% of operations have a clear summary + operationId an agent can select on. Investigated: spec 100%.
- [fail] Machine-readable errors (RFC 9457) — No 4xx/5xx response codes (or default error response) documented anywhere in the spec. Investigated: spec 0%, docs 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 1 assessed pages (1 JS-rendered). Investigated: docs 0%.
- [fail] Description consistency across surfaces — Mean pairwise description similarity across 2 surfaces (spec, sdk) is 0% (threshold 35% for full credit).
- [skip] Agent-navigable, token-efficient docs — 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] Rate-limit signaling — rate-limit behavior documented in the docs site at https://docs.commercelayer.io/core/rate-limits. Investigated: spec 100%, docs 100%.
- [warn] Sandbox separation — No test-mode flag or sandbox environment is exposed. Investigated: sdk 50%, spec 0%, docs 0%.
- [fail] Runnable collection with test scripts — No public Postman workspace discovered for the org. Investigated: platform 0%.
- [skip] Pagination documented & consistent — No surface produced evidence for this capability in this run.

## Executive Summary

Commercelayer's API program shows strong discoverability fundamentals, but partner and agent outcomes are held back by two critical gaps: agents and coding assistants cannot reliably parse your APIs because errors lack machine-readable structure, docs lack AI-consumable formats, and no agent instruction file exists to guide automated tooling. Separately, partners have no self-service portal to onboard independently, and no runnable collection with tests to validate integrations before they hit production. Prioritize making your API surface agent-readable first, then close the runnable truth and self-service onboarding gaps to compress partner time-to-first-call.
