​
Short answer

LaoZhang API is a technical API gateway and routing service for developers. It is not the official operator of upstream models and does not decide whether a user’s input, output, or use case is lawful. Users must review model outputs, have the necessary rights to submit inputs, and comply with applicable law, regional restrictions, and upstream model policies. This page follows the LaoZhang API Terms and Data Policy and was last verified on September 2, 2026. If this page conflicts with a formal policy, the formal policy controls.

​
Service boundary

  • LaoZhang API provides standardized technical access, routing, billing, and usage visibility.
  • Requests are transmitted to the third-party model and infrastructure providers required to complete the task.
  • LaoZhang API does not control upstream models, infrastructure, policies, output quality, or availability.
  • Models, channels, endpoints, prices, rate limits, and features may change for upstream, security, legal, commercial, or operational reasons.
  • Model output may be inaccurate, incomplete, unsafe, infringing, or unsuitable for a particular use.

​
User responsibility

Users must:
  1. have the rights, permissions, notices, and consents required for submitted input;
  2. review and validate output before using, publishing, or making decisions from it;
  3. comply with applicable law, sanctions, export controls, sector rules, and cross-border transfer requirements;
  4. comply with the policies of the upstream model used for the request;
  5. take responsibility for downstream products, customer uses, business decisions, and publications.

​
Prohibited uses

The service must not be used for illegal, harmful, abusive, infringing, deceptive, violent, sexually exploitative, privacy-invasive, discriminatory, malware-related, spam, phishing, surveillance, credential-theft, sanctions-evasion, or other prohibited activities. Users must also not:
  • bypass region, account, or upstream-provider restrictions;
  • create multiple accounts to evade limits;
  • resell API access without authorization;
  • scrape, copy, or reverse engineer non-public systems;
  • probe, attack, overload, or interfere with infrastructure or other users;
  • submit personal, confidential, regulated, or infringing data without the required rights and safeguards.

​
High-impact use cases

For legal, medical, financial, identity, employment, insurance, education-admission, public-safety, or other high-impact decisions, model output should not be used as the sole final decision. Production systems should have appropriate expert review, human escalation, fallback, and record-keeping controls.

​
Account actions

LaoZhang API may suspend, restrict, or terminate accounts, API keys, credits, or access where it reasonably believes that the Terms were violated, security or payment risk exists, upstream restrictions were triggered, or users and providers face legal or operational risk. Unused credits are not refundable when an account is terminated for breach, fraud, abuse, or prohibited use.

​
Pre-production checklist

  • Confirm the business use case and affected users.
  • Record the model, endpoint, token group, and applicable upstream policies.
  • Implement input controls, output review, error handling, and human escalation.
  • Complete legal review for personal, regulated, or cross-border data.
  • Retain necessary metadata without copying sensitive request content into logs or support messages.
  • Monitor the changelog and console for model and route changes.

What to provide to support

When contacting hi@laozhang.ai, provide the account, use case, model ID, endpoint, request time, redacted error, and the specific policy boundary that needs confirmation. Do not send complete API keys, prompts or responses, personal information, or other sensitive material.
