GET /v1/stablecoins

unprobed

Stablecoin supply data. Returns circulating supply for stablecoins broken down across chains via DefiLlama, filterable by peg type and by collateral mechanism, so you can compare fiat-backed against crypto-backed and algorithmic stablecoins. For stablecoin market share, depeg watch, and chain-level supply tracking. Keyless.

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

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.
