## Check Results

### API Design

- [pass] Schema coverage & depth — 2/2 enums are named types (not bare strings). Investigated: sdk 100%.
- [pass] Security & governance hygiene — security.txt valid at https://sardine.ai/.well-known/security.txt (Contact + unexpired Expires). Investigated: wellknown 100%.
- [warn] Example coverage — README is present but has no runnable quickstart. Investigated: sdk 50%, docs 0%.
- [skip] Machine-readable, versioned contract — 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] Changelog published — Newest official SDK activity 0 day(s) ago. Investigated: sdk 100%.
- [warn] Quickstart present — Quickstart page reachable (24 variants scanned starting at https://dashboard.sandbox.sardine.ai/login?redirect_url=%2Flogin-docs%3Freferer%3D%2Fhome%2Fquickstart) but no runnable code sample detected in HTML or .md variant. Investigated: docs 50%.
- [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%.
- [fail] Code samples in docs — No detectable code samples across 17 sampled docs pages. Investigated: docs 0%.
- [skip] Description completeness — No surface produced evidence for this capability in this run.

### Agent Discovery

- [pass] Registry & SDK presence — Indexed on Context7 (websites/payments_sardine_ai, 386 snippets). Investigated: docs 100%, sdk 67%, cli 0%.
- [warn] llms.txt present, valid & comprehensive — llms.txt contains parseable links but doesn't fully follow the proposed structure: https://docs.sardine.ai/llms.txt: No blockquote summary found. Investigated: docs 92%, sdk 0%.
- [warn] Docs reachable, not hard auth-gated — 1 of 1 pages return 200 for non-existent URLs (soft 404). Investigated: docs 75%.
- [pass] Crawlable / AEO — Docs paths crawlable by all monitored AI agents. Investigated: wellknown 100%.

### Agent Understanding

- [warn] Agent-navigable, token-efficient docs — 1 of 1 pages have content starting at 10–50% (worst 11%). Investigated: docs 95%.
- [pass] Docs structured data — JSON-LD Article markup on 2/2 assessed pages (100%) with dateModified present. Investigated: docs 100%.
- [fail] Agent instructions file (AGENTS.md) — No AGENTS.md at the site root or /.well-known/. Investigated: wellknown 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

- [warn] Sandbox separation — No test-mode flag or sandbox environment is exposed. Investigated: sdk 50%.
- [fail] Idempotency documented — No built-in retry machinery was found; transient failures are not retried. Investigated: sdk 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.

## Executive Summary

Sardine's API program shows strong API design and discovery fundamentals, giving partners a solid contract to build against. However, the program has two critical gaps that block partner and agent productivity: agents lack the structured context files and idempotency guidance they need to integrate safely and autonomously, and partners have no self-serve portal or runnable collections to get hands-on without a sales conversation. Prioritizing executable onboarding, agent-readable context, and operational reliability documentation will unlock partner-program velocity and reduce integration support burden.
