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 'status' field (e.g. 'success') and a 'data' object with the firewall evaluation result for the submitted agent context properties. The response confirms whether the agent's context passed the firewall check.
Example use cases
Gate agent tool access by context
“Before my agent calls any downstream tools, check its current context properties through the Swarm Protocol context firewall to verify it's authorized to proceed.”
Policy compliance check for autonomous agent
“My AI agent is about to execute a sensitive workflow — can you run a context firewall validation on its properties using the Swarm Protocol to confirm it meets the access policy?”
Micropayment-secured agent authorization
“Use the Swarm Protocol's agent context firewall to validate whether my agent's context properties are cleared, and pay the 0.05 USDC fee via x402 on Base Mainnet to get the result.”

Endpoint
GEThttps://swarm-protocol.onrender.com/tools/agent_context_firewall?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a machine-payable, micropayment-gated context firewall check for an autonomous AI agent operating on Base Mainnet with USDC. It is best suited for agent-to-agent commerce scenarios where access control must be enforced programmatically via the x402 payment protocol, and where a lightweight per-call fee model ($0.05 USDC) is acceptable.
Side effects
- Payment not received or x402 micropayment rejected — endpoint returns 402 Payment Required
- Invalid or malformed 'properties' input — may return empty or error data object
- Service unavailable on Render free tier cold-start — delayed or 503 response
- No context properties provided — returns empty or default firewall result
- Network timeout on Render hosted service
