## 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 ai-model-pricing-lookup-d694d911
```

Example prompt: Can you look up the current pricing for claude-sonnet-4-5 so I know the per-call rate before I start routing requests through it?

## When to prefer this

Use this endpoint when an AI agent needs to programmatically verify, budget, or audit the cost of calling a specific LLM model before or after invocation, especially when the model is referenced by a short alias or informal name that needs fuzzy resolution to a canonical catalog entry.

## Known failure modes

- Model name not found in catalog — fuzzy resolution may fail for very obscure or misspelled aliases
- Missing required 'name' query parameter returns a validation error
- Service unavailable or 402 payment not processed results in no data returned
- Stale pricing data if the catalog is not updated in real time

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

Returns a JSON object with success status and a result object containing pricing and rate information for the requested AI model, resolved from a catalog via fuzzy name matching on the provided model name or alias.
