Yes. The Free tier is 600 requests a month at 100 requests a minute, across every endpoint in the catalog, with no credit card. Nothing about it expires.

What happens when I hit the quota?

Requests return 429 with the limit, what you have used, and which window you tripped — nothing is queued, and nothing is charged. The monthly quota resets on the 1st (UTC). There is no rollover: unused requests do not carry into the next month.

Do failed requests use up my quota?

A 5xx does not. If a source breaks on our side, the request is excluded from your monthly count. A 4xx does count — a wrong parameter is still a request we answered. Per-minute throttling counts everything, so a retry loop is still throttled.

Which tier do I need?

Start on Free. Every response carries the remaining quota in its headers, and the dashboard reads the same number enforcement uses, so you will see the ceiling coming rather than discovering it.

How is Zapi different from RapidAPI or Apify?

Zapi focuses on a consistent REST contract — one API key, one response format, one error pattern for every source. No need to learn per-provider quirks like on traditional marketplaces, and no need to set up scraping workflows like on Apify.

What about the legality of accessing public data?

Zapi only accesses data that is publicly available without a login. Responsibility for how it is ultimately used stays with the developer — make sure your use case complies with the original source's ToS and the regulations in your operating region.

Is there an official SDK?

One: zpi-sdk, for TypeScript and JavaScript. It carries a typed error hierarchy, retries only what is safe to retry, submits bulk jobs, and verifies webhook signatures. Everything else is plain REST — cURL or any HTTP client works.

Can I request a source that isn't in the catalog yet?

Yes, through the community Discord, on any tier.

Why are Pro and Ultra marked Soon?

Checkout is not open yet. The limits and features listed on those tiers are already built and enforced — what is pending is billing, not the product.

typeenumoptional: Restrict to one entity type. Default all types Values: Gene_Proteins, Chemicals, Diseases, Organisms, Accession Numbers, Gene Ontology, Sequence Ontology, Experimental Methods, Cell, Cell Line, Body Part.
sectionenumoptional: Restrict to one article section. Default all sections Values: Title, Abstract, Introduction, Methods, Results, Discussion, Conclusion.
annotationProviderstringoptional: Restrict to one annotation provider. Default all providers
