The ATXP LLM Gateway provides access to models from multiple providers with transparent, pay-per-use pricing. You can discover all available models and their current pricing through the API.

​
View available models

Query the /models endpoint to see all available models and their pricing: 
curl -X GET "https://llm.atxp.ai/v1/models" \
  -H "Authorization: Bearer $ATXP_CONNECTION_STRING"
When using a model in your API calls, use the model id without the company prefix. For example, to use the gpt-4.1 model via the LLM Gateway, pass gpt-4.1 as the model parameter, not the full ID of openai/gpt-4.1 returned from the models endpoint.

​
Model categories

The LLM Gateway provides access to models across different categories:
  • GPT models: OpenAI’s latest models including GPT-4, GPT-3.5, and more
  • Claude models: Anthropic’s Claude models for advanced reasoning
  • Open source models: Llama, Qwen, and other open-source alternatives
  • Specialized models: Models optimized for specific tasks and use cases

​
Pricing

All models use transparent, pay-per-use pricing based on tokens consumed. Pricing is automatically calculated and charged to your ATXP account balance. You can view current pricing for any model through the /models endpoint.
