Short answer
Current prices, billing units, available models, and credit rules are shown in the console or in commercial terms confirmed with LaoZhang API. Contact the site owner or support for enterprise purchasing, contracts, invoices, volume usage, discounts, or special payment arrangements. The documentation does not publish fixed discount tiers.
Purchased credits and paid fees are generally non-refundable, especially after consumption. Any refund or balance adjustment is handled under applicable law, the LaoZhang API Terms, and an individual review.

Pricing and billing
- Usage may be billed by model, endpoint, token, request, media unit, upstream cost, or another unit shown in the console.
- Prices, available models, rate limits, billing units, and credit rules may change.
- Emergency upstream changes may take effect immediately.
- Do not use an upstream provider’s public price to predict a LaoZhang API bill.
- Use current console pricing and representative call logs for production budgeting.
Enterprise purchasing and discounts
Enterprise purchasing, volume usage, contracts, invoices, discounts, and special payment arrangements do not use fixed documentation thresholds or percentages. Contact the site owner or support and provide:
- company or team name;
- expected models and endpoints;
- estimated monthly usage or budget range;

Refunds and balance adjustments
Generally non-refundable
Purchased credits and paid fees are generally non-refundable, especially after they have been consumed.
Cases that may be reviewed
A refund or balance adjustment may be reviewed where:
- applicable law requires it;
- LaoZhang API permanently discontinues a relevant paid service before credits can reasonably be used;
- a material service failure caused by LaoZhang API prevents normal use for a significant period.
Eligibility, amount, payment-rail availability, fees, and timing are determined through individual review. The documentation does not promise fixed processing times or fees.
Non-refundable cases
These include violations of the Terms, abuse, fraud, sanctions or region restrictions, chargeback abuse, user integration errors, unsupported use cases, upstream-provider restrictions, and dissatisfaction with model output.
What to provide for review
- account email or username;
- transaction time, amount, currency, and payment evidence;
- related model, endpoint, call time, and error information;
- reason for the request and expected resolution;
- contract or invoice details required for enterprise purchasing.
Do not send complete API keys, passwords, or unrelated request content. For call issues, provide only redacted errors, timestamps, models, and request identifiers.
