Charge Skyfire Token
Charge a buyer's token (seller-side operation). REQUIRES SELLER API KEY: This action requires your seller agent API key, not the buyer's key. The buyer creates and sends you a pay/kya+pay token JWT, you provide the service, then call this endpoint to collect payment. Flow: Buyer creates token → Buyer calls your service with token → You validate token → You provide service → You call this to charge. Common errors: - 401: Invalid/expired token OR wrong API key (must use seller key) - 402: Charge amount exceeds token value
