Your link through Anyfare
Put pay.anyfare.agents.bakingbad.dev/ in front of any paid link. The price that counts is the one the API asks at call time.
Pay it from your agent
1
Make a payment key
In the console, with a budget per day and a highest price per call.
2
Give your agent this
Call https://pay.anyfare.agents.bakingbad.dev/api.exa.ai/contents with POST through Anyfare. Pay with my payment key from $ANYFARE_PAYMENT_KEY. Don't pay more than $0.05 for one call.
3
Watch the calls
Each one shows under Last calls, and in your console's Payments.
An agent with its own wallet needs no key. It calls the link, gets our 402, and pays in USDC on NEAR, Base or Solana, or over MPP on Tempo.
