\       escape

^       match start (or negate group)
$       match end

.       match any character (except newlines, [\s\S] to match newlines too)
[]      match range (see examples below)
[^]     negative match range, such as [^<]* (match up to but not including the next `<`)

AiScript Engineer (GPT)

Goal

Create a GPT that can assist me.

It should be able to write code in my style.

Write a "Hello World"-style REST API that uses reCAPTCHA for validation before allowing access to other API routes.

A Simple Demo using Google reCAPTCHA with Express, lovingly coaxed out of GPT4o with a heavy hand.
const express = require('express');
const AsyncRouter = require('@root/async-router');
const fetch = require('node-fetch'); // For making external API requests
const app = AsyncRouter.Router();
// Secret key for reCAPTCHA
const RECAPTCHA_SECRET_KEY = 'YOUR_SECRET_KEY';
app.post('/api/process-payment', async (req, res) => {

Notes on PCI Compliance

Copied from https://github.com/bnnanet/bnna-payment-gateway.js/issues/5 for the immediate benefit of others, to be available as a Public gist until we make the whole repo public (once it's useful).

Key Takeaways

  • We should limit stored data to what's required for a specific, known business purposes
    (not "just in case it's useful")
  • We may, for internal use, salt and hash the full credit card number (with per-vendor salts)
    • We MUST NOT expose that salt or hash via API
  • We may create a 1:1 mapping with a random (or otherwise unrelated) key and the salted hash
  • This is the user-facing identifier
