Why x402
Agents can pay before the meeting starts.
Every brief has a fixed price. The endpoint returns HTTP 402 with machine-readable terms, verifies payment through the GoPlausible facilitator, settles USDC on Algorand, then releases the response.

Public endpoint
Probe it. See the protocol speak.
An unpaid request should return 402. A compatible x402 client reads the terms, pays 0.05 USDC, retries, and receives the full sponsor activation brief as JSON.
