## 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 freetier-agent-api-llm-pricing-free-tier-lookup-7d80799f
```

Example prompt: Pull the full LLM pricing dump so I can compare token costs and free tier limits across all major AI model providers — I want to find the cheapest option for a high-volume chat app.

## When to prefer this

Choose this endpoint when you need a broad, multi-provider snapshot of LLM pricing and free tier availability in a single call, especially when building cost calculators, comparison tools, or budget forecasting features. Prefer this over scraping individual provider pricing pages, as it aggregates and normalizes data across providers with cited sources. Best used when you need structured JSON data ready for computation rather than a human-readable summary.

## Known failure modes

- Payment failure if USDC balance is insufficient or x402 payment flow fails
- HTTP 402 returned if payment is not completed
- Empty models or free_tiers arrays if data is temporarily unavailable
- Stale pricing data if upstream model providers have changed prices recently
