Agent Intel Phone Carrier Hlr Lookup

by SiteCheck Agent Intel & Dev in Documents & files

x402 APIFailing, checked 8 h ago

Parses an international phone number (E.164), checks it against Google's open libphonenumber metadata, and returns the country, line type (mobile, fixed line, fixed-or-mobile, VoIP, toll free, premium, pager and more), E.164/international/national formats and the carrier that the number range was originally allocated to. Not a live HLR query: ported numbers keep the original carrier and active/inactive status is not checked.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://api.fadeandco.workers.dev/api/agent-intel/phone-carrier-hlr-lookup?number=%2B905321234567'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://api.fadeandco.workers.dev/api/agent-intel/phone-carrier-hlr-lookup?number=%2B905321234567' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
JavaScript: pay and call
// npm i @x402/fetch @x402/evm viem
import { wrapFetchWithPayment, x402Client } from "@x402/fetch";

registerExactEvmScheme(client, { signer: privateKeyToAccount(process.env.EVM_PRIVATE_KEY) });
const pay = wrapFetchWithPayment(fetch, client);

// Not sure it's safe to pay? ToolVet checks it first for $0.005. Pay for that from a separate
