SiteCheck

Split a long text into chunks for retrieval (RAG): split on paragraphs, then sentences, then words, each chunk within maxTokens (default 500) with the overlap you ask for (default 50 tokens). Each chunk has its index, text, start and end character offsets and an estimated token count (characters divided by 4, a rough rule for English). Up to 1 MB and 2,000 chunks.

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/chunk", { method: "POST" });
console.log(await res.json());
