## Check Results

### API Design

- [pass] Auth declared & discoverable — Authentication required (global or on every operation). Investigated: spec 100%, docs 100%.
- [warn] Schema coverage & depth — Medium parameter complexity (avg 1 params/op; nested/body schemas present). Investigated: spec 83%, sdk 78%.
- [warn] Machine-readable, versioned contract — info.version="1.0.0" set but no versioning scheme (URL / header / media type) detected. Investigated: spec 75%, docs 50%.
- [pass] Security & governance hygiene — No credential-shaped strings detected in spec. Investigated: spec 100%, wellknown 0%.
- [pass] Example coverage — Code samples in 2 language(s) across docs (top: shell, javascript); 19/20 pages have ≥ 2 languages on the same page. Investigated: docs 100%, sdk 100%, spec 0%.

### Developer Experience

- [pass] Self-service developer portal — Self-service signup at https://ipinfo.io/signup; free tier / sandbox documented. Investigated: docs 100%.
- [pass] Code samples in docs — Code samples in 2 language(s) across docs (top: shell, javascript); 19/20 pages have ≥ 2 languages on the same page. Investigated: docs 100%.
- [pass] Description completeness — 96% of operations + parameters have substantive descriptions. Investigated: spec 100%, sdk 91%.
- [pass] Changelog published — Newest official SDK activity 31 day(s) ago. Investigated: sdk 100%, spec 0%, docs 0%.
- [fail] Quickstart present — No quickstart/getting-started page found at the conventional paths. Investigated: docs 0%.

### Agent Discovery

- [pass] Registry & SDK presence — Indexed on Context7 (websites/ipinfo_io_developers, 2253 snippets). Investigated: docs 100%, sdk 100%, cli 100%.
- [warn] llms.txt present, valid & comprehensive — No llms.txt directive found in HTML of any of 50 sampled pages. Investigated: docs 81%, sdk 0%.
- [warn] Docs reachable, not hard auth-gated — Server ignores Accept: text/markdown header (0/50 sampled pages return markdown). Investigated: docs 75%.
- [pass] Crawlable / AEO — Docs paths crawlable by all monitored AI agents. Investigated: wellknown 100%.

### Agent Understanding

- [pass] Machine-readable errors (RFC 9457) — 6 distinct 4xx/5xx response codes documented. Investigated: docs 100%, spec 50%, sdk 0%.
- [warn] Agent-navigable, token-efficient docs — 6 of 50 sampled pages have content starting past 50% (worst 55%). Investigated: docs 60%.
- [warn] Operation purpose clarity — 88% of operations are agent-inferable (target 90%+). Investigated: spec 50%.
- [warn] Docs structured data — OpenGraph/meta tags only across 19 assessed pages — no JSON-LD for answer engines to cite. Investigated: docs 50%.
- [warn] Description consistency across surfaces — Mean pairwise description similarity across 2 surfaces (spec, docs) is 5% (threshold 35% for full credit).
- [fail] Agent instructions file (AGENTS.md) — No AGENTS.md at the site root or /.well-known/. Investigated: wellknown 0%.

### Agent Usability

- [warn] Sandbox separation — No test-mode flag or sandbox environment is exposed. Investigated: sdk 50%, spec 0%, docs 0%.
- [fail] Idempotency documented — 0% of mutating operations document idempotency. Investigated: spec 0%, docs 0%, sdk 0%.
- [fail] Rate-limit signaling — No rate-limit response headers documented. Investigated: 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

IPinfo's API design and discoverability are strong — partners and agents can find and read the contract reliably. The two areas that need urgent attention are agent usability and agent understanding: there is no runnable, test-backed collection for partners or their AI agents to execute real workflows against, and there is no machine-readable instruction file to orient agents working with the API. Fixing these gaps first will let partners reach a first successful call in minutes and give AI agents the reliable, executable context they need to integrate without guesswork.
