## 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-markets-feed-5a6d50c4
```

Example prompt: Pull me the top 20 current markets from the x402-seller feed so I can see what's actively trading and at what prices right now.

## When to prefer this

Use this endpoint when your autonomous trading agent needs a broad, current snapshot of available crypto markets without stitching together multiple free data sources. It is particularly useful when you need raw market feeds (prices, DEX pools) in a single low-cost call ($0.005 USDC) without API key management.

## Known failure modes

- Payment not included or insufficient USDC — returns 402 Payment Required
- limit parameter is not a valid integer — may return 400 Bad Request
- Server unavailable on Render free tier — may return 503 or timeout during cold start
- Empty or sparse results if no markets currently indexed

## 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

A JSON object containing an array of market entries with current price data, DEX pool information, and other trading intelligence fields. The number of results is bounded by the optional 'limit' parameter.
