What you get#
Onekey exposes Zippopotam as 1 endpoint behind one API key: 1 endpoint return one record (data is an object). Every answer uses the same envelope (success, data, metadata, error), the cost is reported in metadata.credits_charged, and fields are mapped onto the unified schema so the code you write for Zippopotam also works for the rest of the maps, weather & space category.
Endpoints#
| Endpoint | What it does | Parameters | Credits | Status |
|---|---|---|---|---|
postcode | Place, state and coordinates for a postal code (60+ countries). | country*, code* | 1 | stable |
A * marks a required parameter. Each endpoint name links to its reference page with the full parameter table, caching window and a recorded response.
Make a request#
This calls zippopotam.postcode (1 credit, stable). Replace YOUR_API_KEY with your key; sign up, no card. 1,000 free credits cover the open-platform endpoints. Hard-to-reach platforms (X, TikTok, Instagram, Reddit, and others marked on their page) need a verified email and a purchased pack.
curl "https://api.onekey.dev/v1/zippopotam/postcode?country=us&code=90210" \
-H "x-api-key: YOUR_API_KEY"Fields you get back#
These unified fields come back from Zippopotam, with the same names as on every other platform. The count is how many of its 1 mapped endpoints return the field; a field the source lacks is null, never missing. 1 platform-specific field (ext.<name>) come on top, documented on each endpoint page.
| Field | Type | Endpoints |
|---|---|---|
entity.category | string | 1 |
entity.description | string | 1 |
entity.id | string | 1 |
entity.name | string | 1 |
place.lat | number | 1 |
place.lon | number | 1 |
The full schema is in Unified schema.
