POST, PUT, PATCH, DELETE
Outbound methods are restricted to side-effect actions.
Service capabilities
What agents can buy, execute, and verify.
Action402 publishes its paid action, x402 payment settings, verification links, and safety limits through an agent-readable capabilities document.
Safety limits
Bounded execution, not broad automation.
The service keeps the agent-facing action narrow: allowed methods are capped, private network targets are blocked, retries are bounded, and receipts store hashes instead of raw payloads.
HTTPS targets only
Localhost and private network targets are blocked by default.
hmac-sha256 receipts
Jobs link to signed receipts for later verification.
llms.txt + MCP hints
Agents get keywords, copy-paste prompt, and Bazaar discovery flow.
