Agent Intel Cross Chain Bridge Liquidity

by SiteCheck Agent Intel & Dev in Onchain & crypto

x402 APIFailing, checked 5 h ago

Across bridge limits for USDC between two chains: the largest instant-fill amount the bridge can take right now, the largest deposit it accepts, and the smallest deposit. Across only (not Stargate, Hop or CCTP), USDC only, and the chain pair must be one the Across limits API accepts.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

The code pays $0.002 in USDC on Base instead: the x402 libraries don't pay USDC by default.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://api.fadeandco.workers.dev/api/agent-intel/cross-chain-bridge-liquidity?from=8453&to=42161'

# 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://api.fadeandco.workers.dev/api/agent-intel/cross-chain-bridge-liquidity?from=8453&to=42161' \
  | 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 $0.002 per call.
const client = new x402Client().setSpendControls({ maxAmountPerPayment: "$0.002" });
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 $0.002 per payment. GET https://toolvet.app/api/v1/check?url=https%3A%2F%2Fapi.fadeandco.workers.dev%2Fapi%2Fagent-intel%2Fcross-chain-bridge-liquidity
const res = await pay("https://api.fadeandco.workers.dev/api/agent-intel/cross-chain-bridge-liquidity?from=8453&to=42161");
console.log(res.status, await res.text());
