EndpointWhat it doesPriceFree

Try it

curl -X POST "$ORIGIN/v1/echo" -H 'content-type: application/json' -H 'X-Free-Call: 1' -d '{"text":"hello"}'

Routes with free calls allow a few a day per caller: send X-Free-Call: 1. Without it, an unpaid call gets 402 Payment Required with the x402 terms, which x402 clients and agents pay automatically.
