AI agents can access Formo endpoints without a Workspace API key by paying per request through a payment gateway. Two protocols are supported:
  • x402 via formo.x402.paysponge.com: the agent pays 0.05 USDC per request on Base.
  • MPP via formo.mpp.paysponge.com: the agent pays 0.05 USDC.e per request on Tempo.
In both cases the gateway issues a 402 Payment Required challenge on the first request, and a compliant client handles the payment automatically. The response shape is identical to the standard, API-key authenticated endpoint.

​
How it works

  1. The agent sends a request to the gateway URL for the endpoint it wants.
  2. The gateway responds with 402 Payment Required and the payment terms.
  3. A compliant x402 or MPP client signs and submits the payment, then retries.
  4. The gateway proxies the request to Formo and returns the response.
