Already have a key?

  • GET /v1/account/me — your account info (key_id, tier, created_at).
  • POST /v1/account/keys — mint another key under the same account (e.g. for a second deployment, or to rotate).
  • GET /v1/account/usage — daily request counts (rolled-up reporting is a post-launch enhancement; currently returns an empty array under the locked wire shape).
Free tier already gets you most of what you need. If you’re prototyping, just hit the public endpoints directly — no signup required. The 60 req/min anonymous floor works for an exploratory script or a low-traffic embed. Sign up when you want the higher per-key rate-limit + usage analytics, or when you’re ready to ship to customers.
