Entities Transactions

by TraceFast in Onchain & crypto

x402 APIPassing, checked 3 h ago

TraceFast live Ethereum data: the transactions an address sent or received, newest first — each with sender, recipient, value, fee, the called function where its selector is known, the receipt's outcome, and which side of it this address is on (`sender`, `receiver`, or `self` when it is both). Path: address. Query: limit, cursor, direction, status, fromBlock, toBlock (see docs). Docs: https://docs.tracefast.xyz/api/entity-transactions.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 $0.1.

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/entities/:address/transactions?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/entities/:address/transactions?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 $0.1 per call.
const client = new x402Client().setSpendControls({ maxAmountPerPayment: "$0.1" });
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 $0.1 per payment. GET https://toolvet.app/api/v1/check?url=https%3A%2F%2Fmpp.tracefast.xyz%2Fapi%2Fv1%2Fchains%2F1%2Fentities%2F%3Aaddress%2Ftransactions
const res = await pay("https://mpp.tracefast.xyz/api/v1/chains/1/entities/:address/transactions?limit=10");
