Daily-cost percentiles from an illustrative test workload, not paying-customer usage; as of 2026-10-19. Days = balance divided by the unrounded daily cost, rounded as shown. Balance expires after 12 months. Where an estimate exceeds that period, the balance expires first. Actual duration depends on usage.

Pay by program

  1. Top up: POST https://api.pauhu.ai/v1/lds/balance/topup with {"amount": "<amount>", "currency": "EUR", "billing": {"country": "FI", "company": "<registered name>", "vat_id": "<EU VAT number with country prefix>"}}. Use "business_id" in place of "vat_id" when the company has no VAT number; "postal_code" is optional. Sold to businesses only. It answers HTTP 402 with a payment challenge; repeat it with the payment credential.
  2. The answer returns a balance token, shown once. Store it.
  3. Calls send Authorization: Bearer <balance token>; GET https://api.pauhu.ai/v1/lds/balance reads what is left.

With the billing details above, the call answers HTTP 402 with a payment challenge; your program pays by sending the same POST again with Authorization: Payment <credential>. The charge is the top-up plus VAT where it applies to the billing country, and the smallest top-up is EUR 10. Each paid answer then returns its own receipt, which your program can read back later.
