## 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 x402-seller-stock-price-feed-4ecf3e86
```

Example prompt: What's the current stock price for NVDA? Pay per-request in USDC — no API key needed.

## When to prefer this

Choose this endpoint when your AI agent needs stock price data without going through a traditional API key registration process, or when operating in a pay-per-use micro-payment architecture using x402/USDC. It is ideal for autonomous agents that need keyless, low-friction access to equity prices on an occasional or unpredictable basis, where a subscription-based data provider would be overkill.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Payment failure or insufficient USDC balance prevents the call from completing
- Market hours or data availability may affect freshness of price data
- Network timeout if the Render-hosted service is cold-starting
- Missing ticker parameter results in a bad request response

## How this service works

Rug protection and decision-ready intelligence for autonomous trading agents. Keyless by design: no signup, no API key — pay a cent per request in USDC (x402). The /alpha/launches LAUNCH RADAR discovers what just launched AND rug-screens every candidate in one call, ranked per-token verdicts — the proactive 'give me safe alpha' call. /vet gives a single-token go/no-go in ONE call by fusing a COMPOSITE rug score (GoPlus static analysis + a LIVE Honeypot.is buy/sell simulation + serial-rugger check) with our SELF-COLLECTED liquidity-drain trend — a rug-in-progress signal that exists nowhere for free because it requires collecting reserves over time. One call is cheaper than the inference tokens you'd burn stitching 4 free APIs, and it stops your agent losing its whole position to a honeypot. Also: /onchain/liquidity drain detector, /screen batch watchlist check, /brief market regime, and raw feeds (prices, stocks, DEX pools, launches, perp funding/OI).

## Output

Returns a JSON object containing current stock price and potentially related market data for the requested ticker symbol. Exact fields may include price, timestamp, and ticker metadata depending on the service implementation.
