Takes any public NIP-19 identifier or a 64-character hex value and returns every representation it can be expressed as.

Fetches the recent notes of one public key across several relays and measures six independent signals: posting rate per day, the coefficient of variation of the…
Three modes over the same event structure. In preimage mode the caller supplies a public key and the event fields; the answer holds the exact NIP-01 serialisati…
Fetches kind 3 contact lists over up to twelve relays. Because kind 3 is replaceable, several relays regularly hold different versions; only the one with the hi…
Accepts three forms of recipient. A bech32 lnurl is decoded to its callback URL, a Lightning address is resolved through the well-known lnurlp path, and a Nostr…
Fetches https://domain/.well-known/nostr.json with the name query parameter and reads the mapping the domain publishes. The answer states the resolved public ke…
Every relay is measured twice over. Over WebSocket a genuine REQ query is sent and the connection time, the time to end of stored events and the number of event…
Fetches the feed over https with redirect and size limits, recognises RSS 2.0, RDF and Atom, and converts each entry into a NIP-01 event. Kind 1 produces a shor…
Collects kind 9735 zap receipts addressed to one public key over up to twelve relays, merges them by event id and reports who sent how much over the requested w…
Takes a kind 9735 receipt directly or fetches it from relays by event id, then runs eight named checks and reports each one separately with its reason. The rece…
