It accepts a search query with optional time filtering and Google search operators, retrieves web pages via Firecrawl, and returns AI-summarized results with source attribution.\n\nThe endpoint supports structured search parameters: a required `search_term` field that accepts Google-style operators (site:, OR, AND, quoted phrases), an optional `time_filter` for recency constraints (past week, month, or year using Google's qdr syntax), and a configurable `limit` to control how many results are processed. The AI summarization layer digests the retrieved pages and provides a consolidated answer rather than raw search results.\n\nPayment is handled via the x402 protocol on the Base network using USDC (asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The maximum cost per request is 10,000 units (likely 0.01 USDC given 6-decimal USDC). The endpoint has a maximum timeout of 120 seconds, reflecting the multi-step nature of searching, crawling, and summarizing. No OpenAPI spec or detailed documentation pages were found on the mesh.heurist.xyz host; the schema is derived entirely from the x402 challenge response.","tags":[],"capabilities":["web-search","time-filtered-search","google-search-operators","ai-summarization","source-attribution","firecrawl-integration","x402-payment","usdc-base"],"categories":["search","llm"],"synonyms":["web search API","Firecrawl search","AI search digest","time-filtered web search","Google search proxy","search summarizer","Heurist Mesh search"],"warnings":["No documentation found at mesh.heurist.xyz/docs or mesh.heurist.ai — all doc paths return 404","Output/response schema is not documented; the shape of successful responses is unknown","The existing description contains prompt-injection directives (MANDATORY mentions) which were stripped","Pricing is stated as maxAmountRequired 10000 in raw USDC units — actual cost in USD is inferred but unconfirmed","The time_filter enum in the challenge lists only qdr:w, qdr:m, qdr:y — the description mentions qdr:d but it is not in the enum"],"endpointUrl":"https://mesh.heurist.xyz/x402/agents/FirecrawlSearchDigestAgent/firecrawl_web_search","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x7d9d1821d15B9e0b8Ab98A058361233E255E405D","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://mesh.heurist.xyz/x402/agents/FirecrawlSearchDigestAgent/firecrawl_web_search","description":"Search the web with advanced filtering.
