GET /stablecoin/list
live
Catalog of covered stablecoins ranked by market cap, from the DefiLlama stablecoins feed. Each row carries symbol, name, DefiLlama id, peg type, collateral mechanism, total circulating supply, current price and the chains it lives on. Optionally filter by collateral mechanism or by chain. The cheap first step that resolves a symbol to the id the other routes use.
Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
