## Check Results

### API Design

- [warn] Schema coverage & depth — 0/226 (0%) enum-like params are realized as constrained types (not bare strings). Investigated: sdk 86%.
- [pass] Security & governance hygiene — Code is formatter-clean with zero linter errors and zero style warnings. Investigated: sdk 100%, wellknown 0%.
- [pass] Example coverage — README is present and includes a runnable quickstart. Investigated: sdk 100%.
- [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] Description completeness — 1376/1376 operations carry a description. Investigated: sdk 100%.
- [fail] Self-service developer portal — No self-service signup detected — no signup link 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 — so an agent can't onboard on its own. Investigated: docs 0%.
- [fail] Quickstart present — No quickstart or getting-started page found at the conventional docs paths, so new developers and agents have no obvious first step. Investigated: docs 0%.
- [skip] Code samples in docs — No surface produced evidence for this capability in this run.
- [skip] Changelog published — No surface produced evidence for this capability in this run.

### Agent Discovery

- [pass] Registry & SDK presence — Indexed on Context7 (websites/xendit_co, 2494 snippets). Investigated: docs 100%, sdk 100%, cli 0%.
- [warn] Docs reachable, not hard auth-gated — Content negotiation partially supported: 0 correct type, 20 wrong type, 30 HTML only; 30 rate-limited (HTTP 429). Investigated: docs 88%.
- [warn] llms.txt present, valid & comprehensive — No llms-full.txt was found at any candidate origin, so agents can't grab your full docs in one fetch. Investigated: docs 86%, sdk 0%.
- [warn] Crawlable / AEO — No sitemap found via robots.txt or /sitemap.xml on the docs host, so AI search engines have no crawl map for your docs. Investigated: wellknown 50%.

### Agent Understanding

- [pass] Machine-readable errors (RFC 9457) — Single base error "OpenApiException" with 6 subclasses. Investigated: sdk 100%.
- [pass] Operation purpose clarity — Surface uses a single dominant casing convention (camelCase). Investigated: sdk 100%.
- [warn] Agent-navigable, token-efficient docs — 20 of 50 sampled pages have content starting past 50% (worst 102%). Investigated: docs 65%.
- [warn] Agent instructions file (AGENTS.md) — No agents.md or skill.md context file found (nice-to-have for agent operation). Investigated: sdk 50%, wellknown 0%.
- [skip] Docs structured data — 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

- [pass] Idempotency documented — Built-in retry machinery is present (grep-derived). Investigated: sdk 100%.
- [pass] Sandbox separation — Sandbox environments are exposed (sandbox). Investigated: sdk 100%.
- [pass] Runnable collection with test scripts — README is present and includes a runnable quickstart. Investigated: sdk 100%, 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

Xendit's API program performs well on agent discoverability, documentation parseability, and schema quality — partners and their agents can find and understand the API surface once they arrive. The critical gap is at the very front door: there is no self-service signup path and no quickstart, meaning prospective partners cannot get hands-on without a sales conversation, and AI agents have no obvious entry point for onboarding workflows. Closing the onboarding gap should be the immediate priority, as it is the single biggest barrier to partner activation and self-serve growth.
