API Plans

Bluescan exposes a public REST API mirroring the data shown on the website. The same endpoints power the explorer itself, so you get the same correctness, the same caching, and the same response shapes used internally.

Rate limits, in detail

Limits are enforced as a sliding minute window. When you exceed the quota the server returns HTTP 429 with a Retry-After header indicating how long to wait. Every successful response carries the headers below so your client can pace itself without trial and error:

  • X-RateLimit-Limit — your plan's per-minute ceiling.
  • X-RateLimit-Remaining — calls left in the current window.
  • X-RateLimit-Reset — UNIX seconds when the window resets.

How to get an API key

  1. Decide which plan fits your use case. Most production projects start on Pro.
  2. Email [email protected] with a one-line description of your project, expected request volume, and the domain or app the calls will originate from.
  3. We respond with a contract draft and, on signature, issue your key. Keys can be rotated at any time.

Frequently asked questions

Can I switch plans later?
Yes. Upgrades take effect immediately; downgrades apply at the start of the next billing cycle so you do not lose paid-for capacity.
Do you offer a free trial of Pro?
The Free tier is intended to serve as the trial. If you need to test Pro-only features such as higher rate limits or the theme parameter for an evaluation, mention it in your email and we will issue a 14-day evaluation key.
Are there volume discounts?
Yes. Enterprise contracts are negotiated based on volume, infrastructure isolation requirements, and term length.
