FomoScan connects fomo.family wallets to the people behind them: give it a handle and get the wallets that person controls, give it a wallet and get the person behind it. This page gets your first call working, and the full endpoint reference covers every route. For exact request and response shapes, open the interactive Swagger UI (opens in a new tab) or fetch the OpenAPI 3.1 document at GET /openapi.json.

}Resolve a fomo.family handle to its verified wallets, and a wallet back to the handle behind it. Every match is proof-verified, never inferred.

See endpoints →A WebSocket that pushes every new thesis as it is indexed, filtered to a token list or the whole firehose.
See endpoints →Send your key as a bearer token: Authorization: Bearer $KEY. X-Api-Key: $KEY works as an alternative. Production keys start with fsk_live_, sandbox keys with fsk_test_.

This guide and the full reference at /api/docs explain how the API behaves: error semantics, rate limits, what a miss means. The interactive Swagger UI at api.fomoscan.sh/docs is generated from the running service: it lists exact request and response shapes and lets you call an endpoint live with your key. The OpenAPI 3.1 document is at api.fomoscan.sh/openapi.json.
