Technical details
Endpoint
POSThttps://api.strale.io/x402/v2/web-extractWhen to prefer
Choose this endpoint when you need to extract specific named fields from a public web page using a plain-English description of what you want, rather than writing custom scraper code. Particularly useful when the data is not available via an official API and you need an auditable, verifiable extraction with a cryptographic record. Best for structured data pulls (prices, contacts, metadata, tables) from known URLs rather than broad web crawls.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with connectivity error
- Page requires JavaScript rendering and content is not in raw HTML — partial or empty extraction
- Extracted field not present on page — returns empty or null for that field
- Rate limiting or blocking by target site — request may fail or return incomplete data
- Ambiguous natural language extraction query — may return unexpected fields or mismatched data
