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.

US CDC open data — Socrata dataset catalogue and SoQL queries, syndicated public-health content, environmental health tracking and WONDER mortality queries.

GET

Content Search/v1/health:cdc/content-search

7 params

CDC syndicated content (Public Health Media Library). `attribution` and `syndicateUrl` are what make an item legally reusable, so the mapper keeps every one of the 60 upstream fields rather than a summary subset.

Parameters

namestringoptional: Exact item title. The upstream matches the whole title, not a substring
mediaTypestringoptional: Comma-separated media type names from the content-media-types endpoint
topicIdstringoptional: Comma-separated topic ids from the content-topics endpoint
languagestringoptional: Language display name such as English or Spanish
sortenumoptional: Sort order. Default newest by publication date Values: newest, oldest, recentlyUpdated, leastRecentlyUpdated.
pagenumberoptional: Page number. Default 1
limitnumberoptional: Items per page. Default 20, max 100

Request

curl -X GET "https://api.zapi.ink/v1/health:cdc/content-search?name=Asthma&mediaType=HTML%2CVideo&topicId=5288&language=Spanish&sort=newest&page=1&limit=20" \

GET

Content Topics/v1/health:cdc/content-topics

2 params

CDC syndication topic vocabulary — the ids that content-search's topicId accepts. Topics nest one level deep, so each row carries its sub-topics as `children`.

GET

Content/v1/health:cdc/content/:mediaId

1 param

One CDC syndicated media item, with all 60 upstream fields kept. A retired or unknown id answers HTTP 200 with an empty result set rather than a 404, so emptiness is the not-found signal here.

GET

Dataset Count/v1/health:cdc/dataset-count/:datasetId

2 params

Row count for a CDC Socrata dataset, optionally under a SoQL filter. One-shot: the upstream has no page concept here, so no page/limit envelope.

Parameters

datasetIdstringrequiredin path: Socrata four-by-four dataset id. CDC retires ids, so resolve a current one through the datasets endpoint
wherestringoptional: SoQL $where filter. Omit to count every row in the dataset

Dataset Rows/v1/health:cdc/dataset-rows/:datasetId

10 params

Rows from any CDC Socrata dataset via SoQL. The row shape is defined by the dataset's own column schema — NNDSS returns 11 fields, BRFSS 27 — so nothing here assumes a field name. Keys are camelCased and

Parameters

datasetIdstringrequiredin path: Socrata four-by-four dataset id. CDC retires ids, so resolve a current one through the datasets endpoint
selectstringoptional: SoQL $select. Supports count(), sum(), avg(), min(), max(), date_trunc_y, date_trunc_ym, date_trunc_ymd
