## Check Results

### API Design

- [pass] Schema coverage & depth — 111/111 (100%) public params are fully typed (no any/**kwargs). Analyzer confirms all methods have a derivable input schema. Investigated: sdk 100%.
- [warn] Security & governance hygiene — Clean install failed: .ini
    - /etc/php/8.2/cli/conf.d/20-sysvmsg.ini
    - /etc/php/8.2/cli/conf.d/20-sysvsem.ini
    - /etc/php/8.2/cli/conf.d/20-sysvshm.ini
    - /etc/php/8.2/cli/conf.d/20-tokenizer.ini
You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `--ignore-platform-req=ext-dom` to temporarily ignore these required extensions.
. Investigated: sdk 67%, wellknown 0%.
- [pass] Example coverage — README is present and includes a runnable quickstart. Investigated: sdk 100%, 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 7 day(s) ago. Investigated: sdk 100%.
- [warn] Description completeness — 53/85 operations lack a description. Investigated: sdk 38%.
- [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%.
- [fail] Code samples in docs — No code samples detected across 1 sampled docs pages, so a coding agent gets no ready-to-use examples. Investigated: docs 0%.

### Agent Discovery

- [pass] Registry & SDK presence — Indexed on Context7 (websites/developer_nexigroup_nexi-checkout_en-eu, 1064 snippets). Investigated: docs 100%, sdk 25%, cli 0%.
- [warn] Docs reachable, not hard auth-gated — Server ignores Accept: text/markdown header (0/1 pages return markdown). Investigated: docs 75%.
- [warn] Crawlable / AEO — Sitemap has 1 entries but no lastmod values, so crawlers can't tell what changed recently. Investigated: wellknown 75%.
- [fail] llms.txt present, valid & comprehensive — No llms.txt found at any candidate location (https://developer.nexigroup.com/en-EU/llms.txt, https://developer.nexigroup.com/llms.txt, https://developer.nexigroup.com/docs/llms.txt). Investigated: docs 0%, sdk 0%.

### Agent Understanding

- [pass] Machine-readable errors (RFC 9457) — Single base error "PaymentApiException" with 6 subclasses. Investigated: sdk 100%.
- [warn] Agent-navigable, token-efficient docs — No pages support .md URLs (0/1 tested). Investigated: docs 79%.
- [warn] Operation purpose clarity — Read/write classification is mostly ambiguous: only 30/85 operations classified. Investigated: sdk 68%.
- [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%.
- [fail] Docs structured data — No JSON-LD or OpenGraph/meta tags found across 1 assessed pages (1 JS-rendered), so answer engines have nothing to cite. 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

- [warn] Sandbox separation — No test-mode flag or sandbox environment is exposed. Investigated: sdk 50%.
- [pass] Runnable collection with test scripts — README is present and includes a runnable quickstart. Investigated: sdk 100%, platform 0%.
- [fail] Idempotency documented — No built-in retry machinery was found; transient failures are not retried. Investigated: sdk 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

Nexigroup's API design and auth foundations are strong, giving partners a secure surface to build on. However, the program's two critical gaps — the complete absence of a self-service onboarding path and the lack of AI-agent discoverability signals — mean partners cannot get started without a sales conversation, and AI agents cannot find or consume the APIs autonomously. Closing these two gaps should be the immediate priority, followed by adding structured metadata and idempotency guidance to ensure agents can operate reliably and answer engines can surface Nexigroup's APIs in context.
