## Check Results

### API Design

- [pass] Auth declared & discoverable — Authentication required (global or on every operation). Investigated: spec 100%, docs 100%.
- [warn] Schema coverage & depth — 13/13 (100%) public params are fully typed (no any/**kwargs). Analyzer confirms all methods have a derivable input schema. Investigated: sdk 99%, spec 50%.
- [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 50%.
- [pass] Example coverage — README is present and includes a runnable quickstart. Investigated: sdk 100%, spec 0%, docs 0%.

### Developer Experience

- [pass] Changelog published — changelog documented in the docs site at https://docs.perplexity.ai/docs/resources/changelog. Investigated: spec 100%, docs 100%, sdk 100%.
- [warn] Quickstart present — Quickstart page reachable (1 variants scanned starting at https://docs.perplexity.ai/docs/getting-started/overview) but no runnable code sample detected in HTML or .md variant. Investigated: docs 50%.
- [warn] Description completeness — 10/22 operations lack a description. Investigated: sdk 55%, spec 0%.
- [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 20 sampled docs pages. Investigated: docs 0%.

### Agent Discovery

- [pass] Docs reachable, not hard auth-gated — All 1 pages are publicly accessible. Investigated: docs 100%.
- [pass] Registry & SDK presence — Indexed on Context7 (websites/perplexity_ai_help-center_en, 1 snippets). Investigated: docs 100%, sdk 100%, cli 100%, mcp 50%, wellknown 0%.
- [warn] llms.txt present, valid & comprehensive — No /llms-full.txt found at the candidate origins. Investigated: docs 83%, sdk 0%.
- [pass] Crawlable / AEO — Docs paths crawlable by all monitored AI agents. Investigated: wellknown 100%.

### Agent Understanding

- [pass] Machine-readable errors (RFC 9457) — error codes documented in the docs site at https://docs.perplexity.ai/docs/cookbook/articles/function-calling-e2e/README. Investigated: spec 100%, docs 100%, sdk 100%.
- [pass] Operation purpose clarity — 100% of operations have a clear summary + operationId an agent can select on. Investigated: spec 100%.
- [pass] Agent-navigable, token-efficient docs — All 1 pages contain server-rendered content. Investigated: docs 100%.
- [pass] Docs structured data — JSON-LD Article markup on 19/19 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] Description consistency across surfaces — Only 1 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%, spec 0%, docs 0%.
- [pass] Rate-limit signaling — rate-limit behavior documented in the docs site at https://docs.perplexity.ai/docs/admin/rate-limits-usage-tiers. Investigated: spec 100%, docs 100%.
- [pass] Sandbox separation — sandbox documented in the docs site at https://docs.perplexity.ai/api-reference/agent-files-get. Investigated: spec 100%, docs 100%, sdk 100%.
- [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

Perplexity's API program shows strong fundamentals in design, schema quality, and discovery — but two critical gaps are holding partners back. The onboarding experience is the most urgent problem: without a self-service developer portal or in-docs code samples, partners cannot get hands-on without a manual conversation, and AI agents lack the concrete context needed to integrate correctly. Layered on top, the absence of an agent instructions file and a runnable collection with test scripts means agents building on the API are left to guess at workflows and behavior. Prioritize a self-service portal with real code samples first, then add executable collections and agent-facing context files to unlock fully autonomous partner and agent onboarding.
