Questions
- How does the free allowance work?
- Every account gets 1,000 identification requests free each calendar month (UTC), with or without a card. The allowance resets at the start of every month.
- Do I need a credit card?
- No. Sign up and use 1,000 requests a month without one. Add a card in Settings → Billing only when you need more.
- What happens after the free 1,000 requests?
- With a card on file, each 1,000 requests beyond the free 1,000 costs $0.10. Without a card, further requests that month are refused with HTTP 429 (QUOTA_EXCEEDED) until the next month starts or you add one.
- How am I billed?
- Monthly through Stripe, for the requests beyond your free allowance. The rate is $0.10 per 1,000 at every volume, with no plans, minimums or annual contracts.
- What counts as a request?
- Each successful identification call your site makes with your API key. Visitor IDs computed without an API key stay in the browser, never reach TraceTail and are not counted.
- Is there a rate limit?
- Yes: 100 requests per second per API key, to protect the service from abuse. Requests above it receive HTTP 429 with a Retry-After header.
- Can I stop paying at any time?
- Yes. There is no contract. Cancel billing from Settings → Billing whenever you like and you keep the free 1,000 requests a month.
