API & agents

Every stream is JSON and RSS. Free for up to 1,000 calls a day per IP; the Stream API plan or x402 per-call payment lifts that. Responses carry the source on every record.

Agents

The agent card at /.well-known/agent.json follows ecorp-smart-entity/2.0. A minimal MCP endpoint at POST /api/mcp answers tools/list and tools/call for alerts, stream, aq and missions. /api/a2a returns status for agent-to-agent pings. Paid calls: send the x402 payment header described at /api/x402; unpaid calls above the free tier get a 402 with the price.
