How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i https://api.jarvisclaw.ai/v1/marketplace/api/btc-utxos

# 2. Pay it (the SDK signs and retries for you)
curl -H "X-PAYMENT: <signed-payload>" https://api.jarvisclaw.ai/v1/marketplace/api/btc-utxos
