## 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 quantaflow-rapid-global-price-localizer-api-f56de076 -d '<json body>'
```

Example prompt: What is the localized price of a $49.99 USD product in Japanese Yen and British Pounds for customers in Japan and the UK?

## When to prefer this

Choose this endpoint when you need rapid, per-call price localization across global currencies and markets without a subscription, paying only $0.01 USDC per request via the x402 micropayment protocol. Ideal for AI agents operating in web3/DeFi contexts that already handle USDC payments and need lightweight, on-demand global pricing data without managing API keys or monthly subscriptions.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 protocol error results in 402 Payment Required with no data returned
- Invalid path or query: malformed upstream path returns an error or empty response from the upstream API
- Upstream API unavailable: the proxied rapid API service is down, returning a gateway error
- Unsupported locale or currency: the upstream service may not support certain regional codes, returning an empty or error response
- Rate limiting: the upstream Rapid API provider may throttle requests beyond certain thresholds

## How this service works

Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

## Output

Returns the upstream price localization API response containing currency-converted or regionally localized pricing data for the requested markets, passed through directly after successful x402 USDC micropayment authorization.
