Trade tape

const url = 'https://api.getchord.xyz/v1/chains/avalanche/token/example/trades?limit=50';
const options = {method: 'GET'};

try {
  const response = await fetch(url, options);

}

curl --request GET \
  --url 'https://api.getchord.xyz/v1/chains/avalanche/token/example/trades?limit=50'

The token’s swaps straight from the raw tape, newest first: venue, side, size, USD, price, block, wallet (null for a router or an unattributed trade, never a guess) and pool. Keyset-paged: pass nextBefore back as before for the next page; nextBefore is null on the last one. The raw tape is short on these chains (see retentionCutoffDay on /status), so paging stops there.

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”.

Parameters

Path Parameters

chain

required

string

Allowed values: avalanche base bnb arbitrum ethereum 43114 8453 56 42161 1

The chain, by key or id: avalanche or 43114, base or 8453, bnb or 56, arbitrum or 42161, ethereum or 1 (case-insensitive). Arc, Robinhood Chain and Monad are refused with 400 UNSUPPORTED_CHAIN and a pointer to their own routes.

address

required

EVM address, hex, case-insensitive.

string

/^0x[a-fA-F0-9]{40}$/

Token address. The zero address means the chain’s wrapped native token (WAVAX, WETH, WBNB).

Query Parameters

limit

integer

default: 50 >= 1 <= 200

Newest rows.

before

string

/^\d{1,12}(:\d{1,15}:\d{1,9})?$/

Exclusive cursor: the previous page’s nextBefore (ts:block:logIndex), or a Unix second.

chain

integer

token

EVM address, hex, case-insensitive.

string

/^0x[a-fA-F0-9]{40}$/

trades

Array<object>

object

Transaction hash.

string

/^0x[a-fA-F0-9]{64}$/

logIndex

integer

block

integer

dex

string

side

string

Allowed values: buy sell

tokenAmt

Whole tokens.

number

usd

number

priceUsd

number

Unix time, seconds, UTC.

integer

wallet

EVM address, hex, case-insensitive.

string | null

/^0x[a-fA-F0-9]{40}$/

pool

A pool: a 20-byte contract address (V2 / V3) or a 32-byte Uniswap V4 pool id.

string

/^0x([a-fA-F0-9]{40}|[a-fA-F0-9]{64})$/

nextBefore

Cursor for the next page; null when this page is not full.

string | null

ingestFloor

The tape’s ingest floor. BNB Chain runs at $100 today; Avalanche and Base at 0.

object

minTradeUsd

Trades under this USD value (at index time) are not in the index, so every count, volume and candle covers trades at or above it. 0 = every priced trade.

number

history

Floors in force over time, oldest first. Empty when the chain was never floored. Raising a floor does not remove older, smaller rows.

Array<object>

object

usd

Floor in force.

number

fromTs

Unix time, seconds, UTC.

integer

updatedAt

Unix time, milliseconds — when the server built this answer.
