## 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-price-feed-1f9fef37
```

Example prompt: What's the current price of ETH? Just look it up quick — no API key needed, pay the micropayment and get me the number.

## When to prefer this

Choose this endpoint when your agent needs a quick, keyless price lookup and can handle per-call USDC micropayments via x402 — ideal for autonomous trading agents that want to avoid API key management overhead and only pay for what they use.

## Known failure modes

- Invalid or unrecognized symbol returns error or empty response
- Payment not fulfilled results in 402 response requiring USDC micropayment
- Network timeout if Render cold-start occurs
- Stale or missing price data if upstream feed is unavailable

## 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 the current price of the requested asset symbol, suitable for use in trading decisions, portfolio calculations, or pre-trade checks.
