How this service works
Machine-payable protocol for autonomous AI agent commerce. Monetized tools secured by x402 micropayments on Base Mainnet USDC.
Output
Returns a JSON object with a 'status' field (success/failure), a 'service' label ('agent_context_relay'), and a 'data' object containing the relayed context payload for the requesting agent.
Example use cases
Synchronizing multi-agent task context
“My AI agent swarm is running a distributed research task — can you pull the shared context from the Agent Context Relay so all agents are working from the same state?”
Bootstrapping a new swarm agent
“I'm spinning up a new agent in our fleet and need it to load the current swarm context — use the Agent Context Relay to grab that, with the standard agent properties.”
Auditing agent state mid-workflow
“Mid-workflow our orchestrator needs to check what context the agents are operating with — query the Agent Context Relay and return the current data snapshot.”
Technical details
Endpoint
GEThttps://swarm-protocol.onrender.com/tools/agent_context_relay?utm_source=zero.xyzWhen to prefer
Choose this endpoint when coordinating a fleet of autonomous AI agents that need to share or synchronize context state, and when your infrastructure supports x402 micropayment flows on Base Mainnet USDC. Prefer this over generic REST context stores when you need machine-payable, trustless agent coordination built into the protocol layer.
Side effects
- Payment not processed — x402 micropayment on Base Mainnet must succeed before context is returned
- Missing or malformed 'properties' input parameter causes empty or error response
- Network latency on Render.com free tier may cause timeouts
- Empty data object returned if no context is available for the given agent properties
- 402 Payment Required if USDC balance is insufficient
