## 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 modelprices-xyz-cheapest-vision-multimodal-llm-leaderboard-5643e779
```

Example prompt: What's the cheapest AI model right now that can accept image inputs? Pull the full vision model price leaderboard so I can compare input and output token costs across providers like OpenAI, Anthropic, Google, and Meta.

## When to prefer this

Use this endpoint when you specifically need to find or compare AI models that support image/vision input ranked by cost. Prefer this over the general cheapest LLM leaderboard when the image-processing capability is a hard requirement. Use this instead of individual provider pricing tables (e.g. OpenAI or Bedrock) when you want a cross-provider comparison in a single call.

## Known failure modes

- Upstream pricing data unavailable — service may return stale or partial data
- HTTP 402 if payment is not completed via x402 protocol
- No models returned if the filter criteria exclude all vision-capable models
- Hourly refresh delay means prices could be up to 60 minutes behind actual provider changes
