How It Works

Lexicons define the schema for records in the AT Protocol. The Lexicon Store provides a central registry where anyone can discover and verify lexicon schemas:

1. Publish your lexicon to your PDS at com.atproto.lexicon.schema
2. Add a DNS TXT record at _lexicon.{domain} to prove ownership
3. Submit your NSID, DID, or domain via the form above (or we auto-index from the firehose)
4. We verify DNS authority and store verified schemas in the canonical collection
