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 the matched well's ID, origin base URL, tool name, price in USD, the MCP endpoint URL to call directly, and a human-readable explanation of why this well was recommended. The agent should then call the returned origin's /mcp endpoint directly rather than routing through the gateway again.
Example use cases
Routing agent to right MCP tool
“I want to summarize long documents in my agent workflow — which Rainmaker well handles that? Give me the well ID, MCP URL, and why it's the best match.”
Cost-aware tool discovery for pipeline
“My agent needs to do sentiment analysis on customer reviews. Which Rainmaker well is best for that and what will it cost per call?”
Bootstrapping new agentic workflow
“I'm building an agent that needs to geocode addresses. Can you find me the right Rainmaker well to call, including its origin URL so I can connect directly?”
Technical details
Endpoint
POSThttps://rainmaker-gateway.rainmaker-wells.workers.dev/mcp?utm_source=zero.xyz#recommend-well#recommend-wellWhen to prefer
Use this endpoint when your agent needs to dynamically discover which Rainmaker well (MCP tool) to call for a given task, rather than hardcoding a specific tool. It is the entry point for any agent that doesn't yet know which Rainmaker capability to invoke. Prefer the free list-wells alternative if you just want to browse all available wells without paying per recommendation. After receiving the recommendation, always call the returned origin /mcp URL directly to avoid double-charging.
Side effects
- No matching well found for the given keyword — returns an empty or null result
- Ambiguous query matches multiple wells with similar relevance — may return the highest-scored but potentially suboptimal match
- Payment failure via x402 if USDC balance is insufficient — call is not completed
- Gateway timeout if Cloudflare Worker is under load — retry recommended
- Malformed natural-language input may produce a poor match — more specific keywords yield better results
