Technical details
Endpoint
POSThttps://mesh.heurist.xyz/x402/agents/FirecrawlSearchDigestAgent/firecrawl_extract_web_dataWhen to prefer
Use this endpoint when you need specific structured data fields from known URLs or domains, rather than broad search results. Prefer this over general web search when you already know the source URL and want to extract precise information (prices, contacts, listings, etc.) using natural language instructions. Best for targeted extraction tasks on one to many URLs including full domain crawls with wildcards.
Side effects
- URL is inaccessible or returns a non-200 status — partial or empty results returned
- Wildcard domain pattern matches too many pages — timeout or truncated results
- extraction_prompt is too vague — returned data may be incomplete or mismatched
- Target site uses JavaScript-heavy rendering that Firecrawl cannot fully process — missing dynamic content
- Rate limiting on the target site — failed or incomplete crawl
- Invalid URL format in urls array — error response
