SiteCheck

Tone analysis of a text (max 10,000 characters): formality 0-1, sentiment, emotion scores, tone labels such as friendly, aggressive or urgent, and short suggestions. The reading level (Flesch-Kincaid grade) is computed in code with a simple syllable count, so treat it as an estimate. Model judgements are not measurements.

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://api.sitecheck-api.workers.dev/api/text/tone", { method: "POST" });
console.log(await res.json());
