_Draft updated: 2026-06-25. This launch draft is for operational alignment and must receive legal review before production use._
This policy explains prepaid credits, pricing, free credits, refunds, and billing disputes.
Pricing Unit
xskill stores customer balances as integer micro-credits:
1_000_000micro-credits =$1.00$0.02=20_000micro-credits
The active price card is documented in pricing.md. API responses include usage.pricing with the operation, price-card version, units, and customer price applied to the call.
Top-Ups
Customers add prepaid credits through Stripe Checkout.
- Minimum top-up:
$10.00. $10.00credits10_000_000micro-credits.- Credits are added only after Stripe reports a paid Checkout Session and xskill records the ledger credit.
- Checkout Sessions are fulfilled idempotently by Stripe Checkout Session ID, so retries do not double-credit a balance.
Signup and checkout surfaces must link this policy and the Terms of Service before a customer creates a Checkout Session.
Free Tier and Promotional Credits
The default free tier tops each account balance up to a monthly cap. Free credits are account-scoped, not API-key-scoped, and unused free credits do not stack above the cap.
Free, trial, promotional, test, or manually granted non-paid credits are not redeemable for cash and are not refundable.
Usage Charges
Billable routes reserve credits before provider or LLM spend when possible, then settle the usage record to the actual returned units or final operation.
If xskill cannot fetch data because the provider fails before a completed fetch, the route should settle the reservation to zero. If parser or vision work fails after a raw data fetch, the route may still charge the completed raw-data portion according to the active price card.
Consumed API calls are not refundable simply because the output was not useful, because third-party content changed, or because machine-generated parse/OCR output was imperfect.
Refund Eligibility
Subject to applicable law and legal review, Achronon's launch policy is:
- Unused paid credits may be refunded within 30 days of purchase. Refunds go to the original payment method on customer request when supported by Stripe.
- Duplicate payments, mistaken overpayments, or Stripe/payment processing errors are eligible for correction or refund after review.
- Credits consumed by API usage are not refundable unless Achronon determines there was a billing error.
- Free, trial, promotional, test, or manually granted non-paid credits are not refundable.
- Refunds are issued through Stripe to the original payment method when supported by Stripe.
Achronon may deny or delay refunds for suspected abuse, fraud, chargeback risk, account compromise, sanctions/compliance risk, or unresolved payment disputes.
Billing Errors and Disputes
Customers should report billing issues within 30 days of the charge or usage record. Include the account identifier, approximate time, endpoint, request ID or usage ID when available, and Stripe Checkout Session ID for payment issues.
If xskill confirms an overcharge, duplicate charge, failed zero-settlement, or incorrect price-card application, Achronon may correct the balance, issue service credits, or refund unused paid credits.
Chargebacks or payment disputes may cause account suspension while the dispute is reviewed.
Price Changes
Achronon may change the price card, free-tier amount, minimum top-up, rate limits, or cost ceilings. Changes apply prospectively. Existing usage records keep the price-card version and customer price metadata used at the time of the call.
Account Closure
On account closure, unused paid credits remain subject to the same refund eligibility rules. Free, trial, promotional, test, and non-paid credits are removed with the account and are not refundable.
