Independent Cashu mint health data (uptime history, pubkey/fee change log) for escrow

[hroomnik007]

Hi Mostro team, I'm behind MintRadar (mintradar.org), an open-source Cashu mint monitor. I read through the Cashu escrow work (#829, the open Track B/C/D PRs, and #1047 where the maker chooses the mint). Your health event (38389) already probes /v1/info of the mints in mint_urls and of the mints holding escrow. We measure Cashu mints independently from outside and add the history and changes behind that, which might be useful in three places: when an operator picks the allowlist, when a maker picks a mint on an open node, and for escrows already locked in a mint (a mint that goes down or changes its keys or fees later).

We publish measured facts with timestamps and sample sizes (the score is a documented formula you can ignore):

• a public Wallet API (/api/v1/wallets/mints): uptime history, latency, NUTs (incl. 10/11), input fees, keyset info (incl. finalExpiry where the mint publishes it), a log of pubkey/fee/keyset changes (changedSince= filter), and scoreStale/downSince for mints that are down right now
• a signed health feed on Nostr (kind 30385), so a client can check the data came from us unchanged, without trusting the relay or our web server

Would any of that help? Tell us what data you would need and we'll adapt the API.
