## 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 fresh-on-chain-markets-watcher-666016db -d '<json body>'
```

Example prompt: Can you pull up any freshly listed on-chain DeFi markets from the last 24 hours and give me their liquidity, how old they are, and any risk warnings I should know about?

## When to prefer this

Use this endpoint when an AI agent needs to discover brand-new or recently deployed on-chain DeFi markets, especially when liquidity, market age, and risk context are needed together. Prefer this over general liquidity pool endpoints when the recency and freshness of market listings is the primary concern, or when risk notes for newly created pools are required for safe agent decision-making.

## Known failure modes

- No fresh markets found within the queried timeframe — returns empty list or null results
- Invalid or malformed request body — returns 400-style error
- Upstream on-chain data source unavailable — returns timeout or 503
- Payment not processed — returns 402 requiring USDC payment on Base
- Rate limiting or quota exceeded — returns 429

## How this service works

Discover newly listed or fresh on-chain markets and return liquidity, age, and risk notes for DeFi agents.

## Output

Returns a list of newly deployed or recently listed on-chain DeFi markets, each with liquidity metrics, market age, and risk notes (e.g. low liquidity warnings, honeypot signals, age-based caution flags) suitable for DeFi agent decision-making.
