Retry without duplicate recognition charges

Reuse the same operation ID to retrieve a completed result within 24 hours, without generating or charging again.

Pay for successful recognition (USD)

Each successful image starts at $0.002, including 2,000 input tokens and 2,000 output tokens separately. Extra input costs $0.3 per million tokens; extra output costs $1.2 per million. Only usage above each allowance is added.

A new request requires $0.011288 in available balance and reserves that amount. After success, actual usage is charged and the rest is released.

Shared by your API keys; separate from website subscriptions.
