Mint data for P2PK escrow: list mints with NUT-10/11 and no input fee

[hroomnik007]

Hi Shopstr team, I'm behind MintRadar (mintradar.org), an open-source Cashu mint monitor. I saw that the P2PK escrow checkout checks the mint's keyset input fees and supports an allowlist of mints (NEXT_PUBLIC_P2PK_ESCROW_ALLOWED_MINTS). Our public Wallet API can list mints that support NUT-10/11 and charge no input fee:
mintradar.org/api/v1/wallets/mints?nuts=10,11&maxInputFeePpk=0&unit=sat

Every entry has measured facts with timestamps and sample sizes (uptime, latency, fees, keysets, a log of pubkey/fee changes, and scoreStale/downSince if a mint is down). The score is a documented formula you can ignore. There is also a signed health feed on Nostr (kind 30385). It could help you build or review the allowlist, or notice when a mint starts charging fees and would break checkout. Would that be useful? Happy to adapt the API to what you need.
