ToolFit by YourAITools

Check an agent tool list (tools array or public remote MCP URL): grade A-F, estimated tokens per tool and total, compatible yes/no for OpenAI, Anthropic, Gemini, Bedrock and MCP, the top confusable tool pairs, basic poisoning count and a pin (set_id) for later diffs. Bad input or an unreachable URL: never charged.

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.youraitools.co/toolfit/v1/lite", { method: "GET" });
console.log(await res.json());
