## 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`):

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call stock quote without a monthly subscription, especially in agentic workflows that only occasionally need equity prices. Ideal for AI agents operating on x402 micropayment rails (USDC on Base) that need to avoid flat-rate API commitments. Not suited for high-frequency trading where sub-millisecond latency or streaming quotes are required.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error
- Payment failure or insufficient USDC balance blocks the request
- Market closed or after-hours may return stale or delayed data
- Rate limiting or service unavailability from the underlying data provider
- Malformed symbol parameter causes a 4xx response

## How this service works

Global market, government and reference data for AI agents. Pay-per-call over x402 (USDC on Base mainnet).

## Output

Returns a current stock quote for the requested ticker symbol, likely including price, change, volume, and related market data fields in JSON format.
