If you are entering into this API TOS on behalf of a company or other legal entity, you represent that you have the authority to bind such entity to this API TOS.

4A. AI and Automated Systems Usage Restrictions

The credit-based API usage model applies equally to human users and AI/automated systems. However, the following additional restrictions apply to the use of API responses:

Permitted Uses:

Prohibited Uses:

You are expressly prohibited from using API responses or Data for the following purposes:

  1. Training AI Models: Using API responses or Data to train, fine-tune, or improve any artificial intelligence models, large language models (LLMs), machine learning algorithms, or neural networks that compete with or provide functionality similar to Zip-Codes.com services.

  4. RAG Systems for Redistribution: Creating retrieval-augmented generation (RAG) systems, vector databases, or knowledge bases that enable systematic extraction or redistribution of API responses to third parties.
  5. Bulk Data Extraction for Training: Making systematic API calls for the primary purpose of building training datasets or AI models rather than for immediate operational use.

Clarification: You may use AI and machine learning within your Application for processing or enhancing API responses for your end users' immediate benefit, provided such use does not involve training models to replace or compete with Zip-Codes.com services.

Violations of this section constitute a material breach and will result in immediate license termination, mandatory data destruction, and potential legal action.
