What you get#
Onekey exposes Binance as 8 endpoints behind one API key: 6 endpoints return one record (data is an object) and 2 endpoints 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 Binance also works for the rest of the finance & markets category.
Endpoints#
| Endpoint | What it does | Parameters | Credits | Status |

Make a request#
This calls binance.avg_price (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.

These unified fields come back from Binance, with the same names as on every other platform. The count is how many of its 8 mapped endpoints return the field; a field the source lacks is null, never missing. 26 platform-specific fields (ext.<name>) come on top, documented on each endpoint page.
