# Verify Coldkey Signature

`POST /tao/pay/token/verify`

## Request

- Base URL: `https://lium.io/api`
- URL: `https://lium.io/api/tao/pay/token/verify`
- Auth: one of:
  - HTTP bearer
  - API key in header `X-API-Key`

Bind a coldkey to the CALLER, proven by its signature over an access key from GET /token/generate.

## Request body

- VerifyWalletRequest: POST /token/verify's body. ``stripe_customer_id`` may be omitted; if sent it must be the caller's. ``application_id`` is accepted for the old callers and ignored, like ``app_id`` on /wallet/company/: staging's dashboard sends an id that is not this deployment's, and the binding is always this deployment's app.
  - `coldkey_address` string, required
  - `access_key` string, required
  - `signature` string, required
  - `stripe_customer_id` string, nullable
  - `application_id` string, nullable
