How this service works
Pay-per-call: Signal Sprint Base Block
Output
The raw JSON-RPC 2.0 response forwarded verbatim from the seller's MCP endpoint, which may include tool result data, error objects, or argument errors depending on the params supplied.
Example use cases
Invoke a marketplace MCP tool
“I need to call the Signal Sprint Base Block tool on fiatdock — can you send a JSON-RPC 2.0 tools/call request with the right method and params and handle the 0.005 USDC micropayment automatically?”
Automate agent workflow via fiatdock
“My AI agent needs to repeatedly invoke Signal Sprint Base Block as part of a pipeline — can you forward each tools/call request to the fiatdock proxy and pay per call with USDC?”
Test a fiatdock MCP seller tool
“I want to test Signal Sprint Base Block on fiatdock by sending a minimal JSON-RPC 2.0 POST request — can you fetch its callable schema first from the fiatdock marketplace and then fire a sample call?”

Endpoint
GEThttps://fiatdock.com/s/svc_f829d83a-001c-4afe-b51c-2da6f018da96?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to invoke the Signal Sprint Base Block tool specifically via the fiatdock x402 micropayment marketplace and you are prepared to handle JSON-RPC 2.0 request construction. Best suited for automated agents that need to pay-per-call without managing a subscription.
Side effects
- Missing or malformed required params returns an argument error (still billed as a settled call)
- Invalid JSON-RPC 2.0 format causes forwarding failure
- Seller's MCP server is unavailable or times out
- Insufficient USDC balance causes x402 payment failure
- Unknown tool name returns a JSON-RPC error from the seller server
