Pay as you go#
Each completed shared-inference request is billed from authoritative input and output token counts. For a crypto top-up, checkout converts the USD target using a recent CoinPaprika market rate, with Kraken as a fallback. The exact amount is fixed for 10 minutes and rounded up to the asset’s smallest unit; USDT and USDC use actual market rates. A quote records the source, rate timestamp and deadline. Pay network fees separately. No platform deposit fee applies. Shared inference has no monthly subscription; dedicated GPU rentals are prepaid monthly.
Each account top-up must be at least USD 100, including every recharge after the first. Only a confirmed qualifying top-up unlocks AI access; starting a payment or obtaining a quote does not. The minimum is an amount per top-up, not an ongoing minimum balance or a minimum API-key spending cap.
Sign in and confirm a top-up of at least USD 100 before AI use. Each later top-up has the same minimum; after qualification, a smaller remaining balance stays usable when it covers the request. Key permissions, spending caps and model availability still apply. Pending payments do not unlock access. Check service status before sending requests.
Confirmation thresholds#
BTC: 1. ETH: 12. USDT on TRON: 19. USDC on Ethereum: 12. XMR: 10. SOL: 32. LTC: 6. Always use the displayed network.
Ledger-derived balance#
Balance equals the sum of accounting entries. Active reservations reduce the available amount until usage settles. Usage charges aggregate by UTC hour, model and API key. Duplicate provider callbacks cannot create another credit for the same deposit transaction.
Withdrawals#
Wallet withdrawals are currently unavailable. Confirmed prepaid credit can pay for eligible model requests and dedicated GPU orders. Cancelling a paid GPU order before activation returns the rental payment to your WeightsAPI account balance; it does not transfer funds to a wallet.
Billing questions and pending operations#
The FAQ explains reserved credit, key spending caps and the scope of refunds. For a pending payment or interrupted request, follow the support guide. Credit requires transaction verification; a funding order or status refresh cannot confirm payment.
