Returns per-million-token input/output pricing for a catalog of AI models, including model ID, provider, tokenizer family, and context window size

## Facts

## 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 contextiq-token-inspector-model-pricing-aadf6f71
```

Example prompt: Can you pull up the current per-million-token pricing for all available AI models — I want to see input and output costs, context window sizes, and which provider and tokenizer family each model uses?

## When to prefer this

Use this endpoint when you need a consolidated, up-to-date catalog of LLM pricing across multiple providers and models in a single call — especially useful for cost comparison, budget planning, or populating a cost dashboard. Prefer this over scraping individual provider pricing pages or maintaining a manually curated list.

## Known failure modes

- Payment not received or x402 challenge not completed — endpoint returns 402 Payment Required
- Service temporarily unavailable — returns 5xx error
- Pricing data may be stale if generatedAt timestamp is old — no real-time guarantee on underlying provider rates
- Empty or partial model list if upstream provider data is incomplete

## Output
