Create customer HD wallet
Creates a BIP39 HD wallet for a customer. The mnemonic is returned only on creation —
it is encrypted at rest and is not retrievable again except via /seed.
Requires API key + KYC + business account.
Plan limits enforced:
| Plan | Max customer wallets |
|---|---|
| Starter | 20 |
| Professional | 100 |
| Business | Unlimited |
| Enterprise | Unlimited |
Returns 402 if the subscription is expired. Returns 403 with
"code": "WALLET_LIMIT_EXCEEDED" if the plan cap is reached.
