POST /v1/protocols

unprobed

Top DeFi protocols ranked by total value locked (USD), with 1d/7d TVL change, category and chains. Optional filters: `chain` (ranks by that chain's TVL) and `category` (e.g. "Dexes", "Lending"). Centralised-exchange reserves are excluded.

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

curl -si -X POST 'https://crypto.openverbs.com/v1/protocols' -H 'accept: application/json' -H 'content-type: application/json' --data '{}'

The catalog declares POST. 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.
