# T&T Hospitality LLP - Multi-Model AI Chat API

> T&T Hospitality LLP - Multi-Model AI Chat API is a paid API for AI agents from tandt.appziac.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Routes a text prompt to one of 30+ AI models from Groq, OpenAI, Anthropic, Google, DeepSeek, and others, returning the model's text response with token and cost metadata.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability t-t-hospitality-llp-multi-model-ai-chat-api-0dfe27fb -d '<json body>'
```

Example prompt: Send this prompt to claude-sonnet and give me the response: 'Explain the difference between TCP and UDP in plain English, keep it under 150 words.' Use up to 300 tokens.

## When to prefer this

Choose this endpoint when you need pay-per-call access to a wide variety of AI models (30+) without managing separate API keys or subscriptions. It is ideal for agents that need to switch between model providers (e.g. Anthropic vs OpenAI vs Groq) through a single unified interface, or when cost predictability at $0.005/call matters. Prefer alternatives when you need streaming responses, function calling, structured outputs, or embeddings.

## Known failure modes

- Invalid or unrecognized model name returns an error
- Prompt field missing causes a 400 validation error
- Insufficient USDC payment (x402) results in 402 Payment Required
- Token limit exceeded by model constraints
- Provider-side rate limits or outages cause 5xx errors
- Empty or malformed prompt may return an unhelpful or truncated response
