GET /v1/callers

The rated list. Each caller with their receipt score, chain, attributed wallets, signal count and last activity.

chain min_score verified limit cursor

GET /v1/callers/{id}

One caller in full: identity, each wallet with how it was proven, and the score broken into its parts.

include=calls

GET /v1/signals

Calls as they land. Token, direction, timestamp, source link, and the on-chain verdict once it resolves.

chain min_score caller token since verdict

GET /v1/tokens/{token}

Everything said and done on one token — every caller's calls plus their trades, already shaped as chart markers. This is what draws the hero above.

from to resolution

GET /v1/trades

The raw fills behind a verdict, when you want to draw or audit the position yourself.

Errors

401Missing or unknown API key.
