## Check Results

### API Design

- [pass] Schema coverage & depth — 2518/2518 (100%) public params are fully typed (no any/**kwargs). Analyzer confirms all methods have a derivable input schema. Investigated: sdk 100%.
- [pass] Example coverage — README is present and includes a runnable quickstart. Investigated: sdk 100%, docs 0%.
- [fail] Security & governance hygiene — No security.txt at /.well-known/security.txt or /security.txt. Investigated: wellknown 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] Self-service developer portal — Self-service signup at https://telnyx.com/sign-up; no free tier or sandbox language detected. Investigated: docs 100%.
- [warn] Description completeness — 1056/1077 operations carry a description. Investigated: sdk 98%.
- [pass] Changelog published — Newest official SDK activity 0 day(s) ago. Investigated: sdk 100%.
- [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 19 sampled docs pages. Investigated: docs 0%.

### Agent Discovery

- [pass] llms.txt present, valid & comprehensive — llms-full.txt reachable at https://developers.telnyx.com/llms-full.txt. Investigated: docs 100%, sdk 0%.
- [pass] Registry & SDK presence — Indexed on Context7 (websites/developers_telnyx, 14134 snippets). Investigated: docs 100%, cli 100%, sdk 92%.
- [warn] Crawlable / AEO — robots.txt blocks 1 of 7 monitored AI crawlers on docs paths (ccbot). Investigated: wellknown 75%.
- [skip] Docs reachable, not hard auth-gated — No surface produced evidence for this capability in this run.

### Agent Understanding

- [pass] Machine-readable errors (RFC 9457) — Single base error "APIError" with 43 subclasses. Investigated: sdk 100%.
- [pass] Docs structured data — JSON-LD Article markup on 15/15 assessed pages (100%) with dateModified present. Investigated: docs 100%.
- [warn] Description consistency across surfaces — Mean pairwise description similarity across 2 surfaces (docs, sdk) is 7% (threshold 35% for full credit).
- [fail] Agent instructions file (AGENTS.md) — No AGENTS.md at the site root or /.well-known/. Investigated: wellknown 0%.
- [skip] Operation purpose clarity — No surface produced evidence for this capability in this run.
- [skip] Agent-navigable, token-efficient docs — No surface produced evidence for this capability in this run.

### Agent Usability

- [pass] Idempotency documented — Built-in retry machinery is present (grep-derived). Investigated: sdk 100%.
- [warn] Pagination documented & consistent — 166/168 list method(s) return an auto-paginating iterable. Investigated: sdk 99%.
- [pass] Sandbox separation — Sandbox environments are exposed (sandbox). Investigated: sdk 100%.
- [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.

## Executive Summary

Telnyx's API program shows strong operational reliability and agent discoverability, but two areas are holding back partner success: developer onboarding is friction-heavy (no quickstart, sparse code samples), and AI agents lack the structured context they need to integrate without guesswork. Closing these gaps — by publishing a clear machine-readable agent instructions file, adding runnable collections with test scripts, and tightening auth/security hygiene — will let partners and their agents go from discovery to a working integration in minutes rather than days.
