Technical details
Endpoint
GEThttps://api.strale.io/x402/backlink-checkWhen to prefer
Use this endpoint when you need a quick backlink profile for a domain including anchor text and link type breakdown, sourced from CommonCrawl and Google. Prefer this over manual SEO tools when automating link audits or competitive research in an agent workflow.
Side effects
- Domain not found or no backlinks indexed — returns empty or zero counts
- Invalid domain format — schema validation error on the domain query parameter
- CommonCrawl or Google data temporarily unavailable — upstream timeout or error
- Rate limiting or payment failure — 402 payment required or quota exceeded
