🔌 Give Each Customer an API Key

Turn the app you built for yourself into something other people pay to use. These prompts add the parts that make a tool into a product: customer sign-in, plans and trials, limits that mean something, a billing lifecycle that handles the awkward cases, and an admin view so you can see who is actually using it. The unglamorous half nobody enjoys assembling.

Give Each Customer an API Key

Copy

Customers want to connect my product to their systems and I am emailing them keys by hand. Build me an API key manager. A signed-in customer can create a key with a name and a description of what it is for, see the full key once at creation and only its last few characters afterwards, and revoke or rotate it themselves without contacting me. Record the creation date, last used date and the number of calls per key over the current period, and count that usage against the account plan allowance. Let me set which capabilities a key can be scoped to. Add an AI agent that watches key usage and flags anything unusual, such as a sudden jump that suggests a loop, a key not used for months that should probably be revoked, or an account approaching its allowance because of one key. Automate two things: an alert to the customer when a key is nearing the allowance or has not been used in a long time, and a scheduled monthly usage summary per account. Two logins: a customer who manages only their own keys, tested with a second account, and an owner who sees all keys and usage.

// the spark catches · intelligence awakens · the answer unfolds

The moment customers want to connect your product to theirs, you need key management. This issues, scopes, and revokes keys, and shows usage per key.

What's Included

  • Keys issued per account with a name and purpose on each.
  • Usage counted per key so a runaway integration is visible.
  • Self-service rotation and revocation without a support ticket.
  • An assistant that flags unusual usage on a key.

How To Use

  1. Let customers name their keys. An unlabelled key is never revoked.
  2. Show the key in full once, then only the last few characters.
  3. Count usage per key. It is how you find a broken integration.
  4. Make rotation self-service or it will simply never happen.

Count it against limits with usage metering, and document it with developer documentation.
