How this service works
Keyword-route a natural-language need to the best Rainmaker well ($0.005 USDC via x402). Returns well id, origin, tool, price_usd, mcp URL, and why. After recommend, open that origin's /mcp directly — gateway does not proxy (avoids double-charge). Free alternative: list-wells. Provided as is, with no warranty or guarantee of accuracy or fitness. Nothing is stored.
Output
A JSON object containing the matched well's ID, its origin URL (the actual MCP server to call directly), the tool name, price in USD, the MCP endpoint URL, and a plain-English explanation of why this well was chosen for the stated need. The gateway does not proxy the call, so the agent must follow up by connecting to the returned origin MCP URL directly.
Example use cases
Route PDF extraction need to best well
“I have a PDF with data tables and need to extract them programmatically — find me the best Rainmaker well for that, with its MCP URL and cost.”
Discover URL monitoring tool on Rainmaker
“I want to watch a webpage and get notified if its content changes — which Rainmaker well handles that kind of monitoring? Show me the tool name, price, and where to connect.”
Find cheapest Rainmaker well for text summarization
“I need a tool that can summarize long documents — which Rainmaker well is the best match for text summarization, and what does it cost per call?”
Technical details
Endpoint
POSThttps://rainmaker-gateway.mmelnyk2000.workers.dev/api/recommend-well?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to dynamically discover which Rainmaker well best satisfies a natural-language capability need, especially within automated pipelines that must route tasks across multiple specialized MCP tools. Prefer this over manually browsing Rainmaker wells or using the free list-wells endpoint when you need a targeted recommendation with reasoning rather than an unfiltered list.
Side effects
- Vague or ambiguous 'need' string may return a poorly matched well
- No matching well exists for a highly niche or unsupported capability
- Service may be unavailable if the Cloudflare Worker is down
- Double-charging risk if the agent mistakenly calls the gateway as a proxy instead of connecting directly to the returned origin
- Returned well may be temporarily offline or have changed its pricing
