How this service works
Machine-payable protocol for autonomous AI agent commerce. Monetized tools secured by x402 micropayments on Base Mainnet USDC.
Output
A JSON response containing a 'data' object with the tool result, a 'status' field (e.g. 'success'), and a 'service' field identifying the backend registry or tool invoked (e.g. 'agent_trust_registry').
Example use cases
Agent trust verification lookup
“Check the agent trust registry via Swarm Protocol for this agent ID — pay the micropayment automatically and tell me what trust status it returns.”
Monetized tool call in autonomous pipeline
“My AI agent pipeline needs to call a monetized Swarm Protocol tool right now — submit the tool request with the x402 payment on Base Mainnet and return whatever data comes back.”
Commerce infrastructure access for agent fleet
“I'm running a fleet of autonomous agents and need to call the Swarm Protocol commerce endpoint for each one — handle the 0.01 USDC micropayment per call and log the results.”
Technical details
Endpoint
GEThttps://swarm-protocol.onrender.com/mcp/v1/call?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to invoke a machine-payable, micropayment-gated tool call within the x402 Swarm Protocol ecosystem, specifically when your agent operates on Base Mainnet USDC and needs access to the agent trust registry or other Swarm Protocol commerce infrastructure. Prefer this over generic HTTP APIs when you need the x402 payment rail and MCP-compatible agent tool invocation in a single call.
Side effects
- Payment failure: insufficient USDC balance or x402 payment not accepted, resulting in 402 Payment Required response
- Invalid properties input: malformed or missing tool properties field causing a bad request error
- Service unavailable: Render.com hosting may have cold starts or downtime, returning 503
- Unrecognized tool: if the specified tool is not registered in the swarm, returns an error in the data object
- Network timeout: long cold-start on free Render tier may cause timeouts
