Estimate = request count × max(average tokens × rate / 1,000,000, minimum / request). Zero requests = 0. Zero billable tokens = 0.

Actual billing sums each request's charge. Uneven token usage may produce a different total because the minimum applies separately to every request.

Excludes account-specific promotions, conditions or rates. Amounts are shown in VND; this is an estimate, not an invoice. Image/video parameters such as duration or configuration can change the charge; this estimate uses the base rate.

How billing works

Understand the billing unit before calling the API

Billing units and minimums depend on the model ID. Compare listed rates with usage logs to review charges.

Tax and invoice terms follow the Pricing policy. Contact support if you need a VAT invoice. Pricing policy

Per token

Charges use actual input and output tokens at the model’s listed rate. A minimum charge per call may apply.

Use the normalized billable token total, including input, output and cache. Cache reads and writes are charged at the full current rate; do not add cached tokens again when the SDK total already includes them.

  • Rates shown per 1 million tokens
  • Check the minimum for each model ID
  • Review tokens and charges in usage logs

Per call

Applies to models listed per call, including some LLM chat models and image, audio or video models.

  • Check the unit on each price row
  • Charges follow the model and recorded usage
  • Failed calls follow reconciliation policies

Balance and invoices

Questions and answers

Pricing and payment questions

Information about billing units, balances, integration and invoices.

What is the minimum top-up, and does the balance expire?
Standard VietQR top-ups start at VND 50,000. Each eligible account may make one VND 10,000 trial top-up. Wallet balances do not expire.
Can a business get a VAT invoice?
ThAPI supports VAT invoices on request. Contact support with the recipient’s business details and relevant transactions for instructions.
How do I attach an API key in Cursor, Cline, or my app?
Choose the guide for your tool, then configure its API key, base URL and model ID. OpenAI SDK, Anthropic SDK, Cursor and Cline have different settings; follow the integration docs for the correct endpoint.
Am I charged when a call fails?
Charges depend on the model, recorded usage and applicable payment and reconciliation policies. An HTTP error code alone does not determine billing. Check the call log and contact support for transaction review.
Is there a separate quote for high volume?
Contact support with the models you need and expected volume. Only confirmed quote terms apply; this page does not promise a fixed discount.
How do token rates, per-call rates and minimums differ?
Token-billed models use input and output tokens at listed rates; a per-call minimum may apply by model. Per-call pricing also includes some LLM chat models. Check the exact model ID, unit and minimum in the price list; estimates do not replace actual recorded charges.
