What you get#
Onekey exposes Wayback Machine as 3 endpoints behind one API key: 2 endpoints return one record (data is an object) and 1 endpoint return a list (data is an array). 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 Wayback Machine also works for the rest of the web tools category.
Endpoints#
| Endpoint | What it does | Parameters | Credits | Status |
|---|---|---|---|---|
available | Most recent Wayback Machine snapshot of a URL. | url* | 1 | stable |
closest | Wayback Machine snapshot closest to a given date. | url*, timestamp* | 1 | stable |
snapshots | Wayback Machine CDX index: successful captures of a URL (one per day, newest 25). | url* | 5 | 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.

This calls wayback.available (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/wayback/available?url=example.com" \
-H "x-api-key: YOUR_API_KEY"Fields you get back#
These unified fields come back from Wayback Machine, with the same names as on every other platform. The count is how many of its 3 mapped endpoints return the field; a field the source lacks is null, never missing. 4 platform-specific fields (ext.<name>) come on top, documented on each endpoint page.
| Field | Type | Endpoints |
|---|---|---|
entity.createdAt | ISO 8601 date | 3 |
entity.url | URL | 3 |
listing.available | boolean | 2 |
The full schema is in Unified schema.
