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 dopaminedesk-ai-model-pricing-api-3902537b
```

Example prompt: Pull the latest pricing for OpenAI and Anthropic models — I need input cost, output cost, and context window for each so I can figure out which LLM is cheapest for my use case.

## When to prefer this

Choose this endpoint when you need structured, machine-readable AI model pricing data with context window details for cost optimization decisions, especially if you are already using the x402 USDC micropayment stack and want a single low-cost lookup rather than scraping multiple provider documentation pages.

## Known failure modes

- Invalid provider filter value returns empty models array
- Stale pricing data if upstream sources haven't updated recently — check updated_at timestamp
- Payment failure via x402 if USDC balance is insufficient results in 402 response
- Network timeout from Cloud Run cold start on first call

## How this service works

Fetch a current third-party aggregated model-pricing snapshot from LiteLLM. Buyers should verify final pricing with each provider.

## Output

A JSON object containing an array of AI model records — each with model ID, provider name, input cost per 1M tokens, output cost per 1M tokens, and context window size — plus a timestamp indicating when the pricing data was last updated.
