Billing policy
Use one API key to read data, inspect request IDs and track the exact cost of each request.
USD balances and reservations
One dollar equals 1,000,000 integer microdollars. We reserve the maximum amount shown on the endpoint page before contacting the provider. Concurrent requests share the available balance.
- Per call
- A valid successful page costs one unit, including an empty page.
- Per item
- Short pages cost only the number returned, an empty page is free. Reserve up to 100 items. Oversized or malformed pages fail without a charge.
- Timeouts and retries
- Gateway failures release the reservation. Each next page is a new request. There are no automatic upstream retries. An interrupted hold is recovered after two minutes plus the maintenance interval.
- Refunds
- An approved usage refund credits the wallet. A successful payment refund deducts the refunded funds. Spent funds may leave a negative available balance, which blocks further calls.
