Length of a text in the units that matter: UTF-8 bytes, UTF-16 units, Unicode code points, user-perceived characters (graphemes, so a flag or family emoji counts once), words and lines. Use it to check limits for APIs, tweets, databases and prompts.

Call it from code

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

import { x402Client, wrapFetchWithPayment } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

const client = new x402Client();
registerExactEvmScheme(client, { signer: agentAccount });

const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://fastx402.tools/text-count", { method: "GET" });
console.log(await res.json());
