Apify Nostr Actor (NIP-19 and NIP-05 Fetcher) This Apify actor fetches and normalizes Nostr profile data from nip19 identifiers (such as nprofile, npub, nevent, note) or nip05 addresses (ex: odell@primal.net). It returns structured JSON output containing parsed metadata (display name, picture, about text, etc.) for each. ## Input The actor expects an input JSON object with a nip19 key containing an array of identifiers. ### Example bash apify run --input='{ "input_ids": [ "nprofile1qqsqfjg4mth7uwp307nng3z2em3ep2pxnljczzezg8j7dhf58ha7ejgpqqgze743", "npub1uzt238htjzpq39dxmltlx60vxym9fetk9czz6kddq6fhvkf4z3usy9qtrh", "npub1g9ysswt67fnyqfrsgtd8l9p0eyccxlydn5eq0cn3evhm9w7e5nkssvzlky", "spritereplace98@walletofsatoshi.com", "note1z6r4jupzuuk6pmxgmluxtlr93s4m57cm98lple2dmjs42e42rc4q4wqdvs" ] }' ## Output The output is a JSON array of objects, where each object represents a decoded Nostr profile with all its metadata.

The actor queries the Nostr relays to fetch the corresponding event. The JSON content of the event is parsed into a structured object for easy consumption. ## Example Usage in Code If you want to call this actor programmatically from Node.js: js import { Actor } from 'apify'; await Actor.init(); const input = { input_ids: [ 'nprofile1qqsqfjg4mth7uwp307nng3z2em3ep2pxnljczzezg8j7dhf58ha7ejgpqqgze743', 'Odie@primal.net' ], }; const run = await Actor.call('grimtechnet/nostr', input); console.log(run.output); ## Notes * Under the hood, we use https://github.com/fiatjaf/nak
