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.
Output
Returns a JSON object containing: well_id (unique identifier), origin (the well's base URL to call directly), tool (tool name), price_usd (cost per call), mcp_url (the MCP endpoint to connect to), and why (a short explanation of why this well was recommended for the query). The gateway does not proxy the actual well call — the agent must open the returned origin/mcp URL directly to avoid double-charging.
Example use cases
Routing to a coding assistant well
“I want to use a Rainmaker well that can help me write and debug Python code — which one should I use and what's its MCP URL?”
Finding cheapest data extraction tool
“Which Rainmaker well is best for scraping and extracting structured data from web pages? Give me the one with the lowest price and its origin URL.”
Discovering image generation well
“I'm building an agent that needs to generate images — recommend the right Rainmaker well for that and tell me why it's the best fit.”
Technical details
Endpoint
POSThttps://rainmaker-gateway.mmelnyk2000.workers.dev/mcp?utm_source=zero.xyz#recommend-well#recommend-wellWhen to prefer
Use this endpoint when an agent needs to dynamically discover and route to the best Rainmaker well for a given task without knowing the well catalog in advance. It is ideal for orchestrator agents that need to delegate subtasks to specialized AI tools listed on Rainmaker. If cost is a concern and discovery (not recommendation quality) is sufficient, use the free list-wells endpoint instead. Prefer this over manually browsing the Rainmaker catalog when the task description is in natural language and you want a ranked, reasoned recommendation.
Side effects
- No matching well found for the given query — returns empty or error response
- Ambiguous query leads to a low-confidence or suboptimal match
- Payment of $0.005 USDC via x402 fails if wallet is underfunded or x402 is not configured
- Rate limiting or worker timeout on the Cloudflare Workers edge function
- Stale well catalog — a recommended well may have changed its price or gone offline
