These are observations, not accusations. A band of LOW, MEDIUM or HIGH describes how much of what we check we were able to confirm — it is not a judgement about the operator of an endpoint. Every signal, its weight and its rationale are published on the methodology page, and any operator can claim an endpoint, correct a fact or opt out.

Test with tx402 →

Pre-filled with this endpoint's real terms. Your signer stays in your process — this service never sees a key, never asks for one, and cannot build a payment.

CLI — dry run, nothing is signed

npx tx402 call "https://x402.jmthomasofficial.com/v2/api/edgar-company-lookup" \
  --max-spend "0.002000 USDC" \
  --network "eip155:8453" \
  --dry-run

# --dry-run stops after the policy decision. Nothing is signed and nothing is spent.

TypeScript

import { createTx402Client } from "tx402";
// Your signer stays in your process. tools.tx402.io never sees a key,
// never asks for one, and cannot build a payment.
import { signers } from "./signers.js";

const tx402 = createTx402Client({
  signers,
  policy: {
    maxPerRequest: "0.002000 USDC",
    allowedDomains: ["x402.jmthomasofficial.com"],
    allowedNetworks: ["eip155:8453"],
  },
});

// Policy and budget are committed before the signer is reachable, so a
// refusal here is a payment that was never authorized.
const response = await tx402.fetch("https://x402.jmthomasofficial.com/v2/api/edgar-company-lookup");

Python
