Avalanche, Base, BNB Chain

Reference price from CoinGecko

CoinGecko's price and 24-hour change for a token by contract address, for a token Chord's index has not seen trade (or to cross-check one it has). Not Chord's own data: the answer says so in source. Cached two minutes; ageS is the age of the cached CoinGecko answer.

Chain-keyed data for Avalanche C-Chain, Base and BNB Chain, served from Chord's rollup tables for the chain (every swap summed by hour, token and venue). Only the trade tape, the prints ticker and the wallet read raw rows, scoped to one token or one wallet and bounded.

  • Access. No key needed while the chain is public (all three are today). A chain whose tape is off, or that is not public yet, answers 400 UNSUPPORTED_CHAIN ("chain N is not served yet") unless the request carries an X-API-Key; those answers are sent Cache-Control: private.
  • Ingest floor. Every count, volume and print covers trades at or above the chain's floor, returned as ingestFloor. BNB Chain runs at $100 today; Avalanche and Base at 0.
  • Readiness. 503 NOT_READY until the chain's rollup has run on this deployment; 503 CHAIN_DATA_UNAVAILABLE when the store cannot be read. Never treat either as "no trades".
