## When to prefer this

Choose this endpoint when you need a programmatic, per-URL SEO audit with a verifiable audit trail (cryptographic chain hashing). Ideal for agents that need to check SEO health as part of an automated content or publishing workflow, or when you need tamper-evident records of audits. Prefer this over general web scrapers when you specifically need structured SEO signal extraction rather than raw HTML.

## Known failure modes

- Invalid or unreachable URL returns an error
- Paywalled or login-gated pages may not be fully crawlable
- Rate limiting or payment failure (x402) if USDC balance is insufficient
- Pages with heavy JavaScript rendering may produce incomplete results
- Malformed URL input causes validation error

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns a structured SEO audit report for the submitted URL, including findings on on-page factors (meta tags, headings, content quality), technical SEO signals, and potential issues. Each call also returns a cryptographic audit record with chain hashing for provenance verification.
