## Check Results

### API Design

- [pass] Machine-readable, versioned contract — Versioning declared (info.version="1.9.0") and header-versioning detected. Investigated: spec 100%, docs 100%.
- [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%.
- [warn] Schema coverage & depth — High parameter complexity (avg 5.1 params/op + nested params). Investigated: spec 50%.
- [pass] Example coverage — 54% example coverage (target 80%+). Investigated: spec 100%, docs 0%.

### Developer Experience

- [pass] Description completeness — 85% description completeness (target 90%+). Investigated: spec 100%.
- [fail] Self-service developer portal — No self-service signup detected: no signup link found on the homepage or docs, and no conventional signup path (/signup, /sign-up, /register, /get-started, /console/signup, /dashboard/signup, /try, /try-free, /free, /free-trial, /start, /start-free, /join, /create-account, /account/signup, /auth/signup, /users/sign_up) resolved. Investigated: docs 0%.
- [fail] Quickstart present — No quickstart/getting-started page found at the conventional paths. Investigated: docs 0%.
- [fail] Code samples in docs — No detectable code samples across 1 sampled docs pages. Investigated: docs 0%.
- [fail] Changelog published — No changelog URL or mention found in spec metadata. Investigated: spec 0%, docs 0%.

### Agent Discovery

- [warn] Docs reachable, not hard auth-gated — Server ignores Accept: text/markdown header (0/1 pages return markdown). Investigated: docs 75%.
- [warn] Registry & SDK presence — Discovered SDKs in only 1 language(s); target ≥3. Investigated: sdk 50%, docs 0%, cli 0%, mcp 0%, wellknown 0%.
- [warn] Crawlable / AEO — No sitemap discoverable via robots.txt or /sitemap.xml on the docs host. Investigated: wellknown 50%.
- [fail] llms.txt present, valid & comprehensive — No llms.txt found at any candidate location (https://developer.candescent.com/llms.txt, https://developer.candescent.com/docs/llms.txt). Investigated: docs 0%.

### Agent Understanding

- [pass] Machine-readable errors (RFC 9457) — 16 distinct 4xx/5xx response codes documented. Investigated: docs 100%, spec 50%.
- [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 — 1 of 1 pages appear to be client-side rendered SPA shells (root detected); agents using HTTP fetches will see no content. Investigated: docs 57%.
- [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%.
- [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 — 0% of mutating operations document idempotency. Investigated: 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] Sandbox separation — No sandbox/test server declared across 1 server entries; no test-key prefixes documented. Investigated: spec 0%, docs 0%.
- [fail] Runnable collection with test scripts — No public Postman workspace discovered for the org. Investigated: platform 0%.

## Executive Summary

Candescent's API design foundation is strong, and documentation is reachable and crawlable — but the partner program has critical gaps that will stall integrations before they start. There is no self-service onboarding path (no portal, no quickstart, no code samples, no changelog), and partners' AI agents cannot reliably execute workflows against the API (no sandbox, no idempotency or rate-limit guidance, no runnable collection). The immediate priority is standing up a self-service developer portal with runnable examples, then layering in the agent-readiness signals — discovery metadata, structured context files, and operational reliability documentation — that let agents integrate without human intervention.
