Tokens Transfers

by TraceFast in Onchain & crypto

x402 APIPassing, checked 3 h ago

TraceFast live Ethereum data: the transfer events of one token contract, newest first — the parties, the raw amount (unscaled) or token id, the event kind, the transaction that emitted it and who sent that transaction, which on a router or a batch disburser is another party entirely. Path: token. Query: limit, cursor, from, to, eventType, fromBlock, toBlock (see docs). Docs: https://docs.tracefast.xyz/api/token-transfers.md

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.05.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://mpp.tracefast.xyz/api/v1/chains/1/tokens/:token/transfers?limit=10'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://mpp.tracefast.xyz/api/v1/chains/1/tokens/:token/transfers?limit=10' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
JavaScript: pay and call
// npm i @x402/fetch @x402/evm viem
import { wrapFetchWithPayment, x402Client } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

// Pays at most $0.05 per call.
const client = new x402Client().setSpendControls({ maxAmountPerPayment: "$0.05" });
registerExactEvmScheme(client, { signer: privateKeyToAccount(process.env.EVM_PRIVATE_KEY) });
const pay = wrapFetchWithPayment(fetch, client);

// Not sure it's safe to pay? ToolVet checks it first for $0.005. Pay for that from a separate
// client: this one is capped at $0.05 per payment. GET https://toolvet.app/api/v1/check?url=https%3A%2F%2Fmpp.tracefast.xyz%2Fapi%2Fv1%2Fchains%2F1%2Ftokens%2F%3Atoken%2Ftransfers
const res = await pay("https://mpp.tracefast.xyz/api/v1/chains/1/tokens/:token/transfers?limit=10");
console.log(res.status, await res.text());
Python: pay and call
# pip install "x402[requests,evm]"
