geoprimitives /v1/hello APIPOST /v1/hello · x402 API by geoprimitives
Echo endpoint. Returns the name you send, the network the payment settled on, and the price you paid. Use it to prove your x402 client works end to end -- discover, read the 402, sign, retry, get a body -- before you spend anything on a real endpoint. It is the cheapest route in the catalog and it computes nothing, so a failure here is a payment problem and never a geospatial one. Do not use it for anything else: it has no geospatial behaviour at all. It is priced at exactly what it costs us to settle one onchain transaction, so the whole of what you pay here goes to the facilitator and none of it to us. That is deliberate: this route is worth having only because it is genuinely paid, since a free echo would prove nothing about whether your client can pay.
