Transparent Credits
One credit pays for one successful retrieval request, whether the response contains one record, 100 records, or no matching records. The per-request record limit is 100; it is not a separate billing unit. Invalid requests do not debit your balance, and upstream failures refund the reserved credit. The public /v1/status route is uncharged.
The rate is $1 per 1000 credits, or $0.001 for one credit. A minimum paid top-up of $50 therefore buys 50000 paid credits, enough for 50000 successful retrieval requests at that rate. Paid credits do not expire, and there is no recurring subscription. The top-up minimum is a funding requirement, not a balance you must continually maintain.
Trial and Top-Up
An eligible account may receive an optional 100-credit trial before making a paid top-up. Eligibility is subject to network-wide anti-abuse limits, so the trial is not guaranteed for every account. Use any available trial balance to check your query and response handling. Those conditional trial credits are separate from the 50000 paid credits purchased with $50.
To add paid credit, sign in and create an invoice in the account panel. Read its token, network, receiving address and exact amount before sending funds. The invoice expires one hour after creation; follow the current invoice instructions for your transfer. After payment, submit the transaction hash for verification. Invoice expiry does not establish a deadline for clicking Verify.
Payment Methods
We support two primary cryptocurrency networks for all top-ups. You can send USDT using the TRC20 network or USDC on the Ethereum mainnet. It is critical that you use only the specific receiving address and exact amount displayed on your generated server invoice. Do not rely on static public addresses, as the invoice dictates the exact recipient and value for the current payment session.
Submit the hash of the actual payment transaction, not a block hash. Credit is added after the server verifies a confirmed genuine transfer against the invoice. Verification may remain pending when confirmation or provider information is unavailable, and no fixed settlement time is promised. There is no wrong-network or wrong-token recovery service or manual payment-investigation service; check the invoice carefully before sending.
