GET /v1/btc/fees

unprobed

Recommended Bitcoin transaction fee rates in sat/vB (fastest, half-hour, hour, economy, minimum) from mempool.space, computed from the live mempool. Optional ?include=difficulty adds the current difficulty retarget estimate (change %, remaining blocks/time). No required params; served with a 60s cache.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

Try it (unpaid: shows the 402)

curl -si -X GET 'https://data.greeneris.io/v1/btc/fees' -H 'accept: application/json'

The catalog declares GET. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
