## 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 base-intel-api-jakemaxsigal-workers-dev-e68f9dd3 -d '<json body>'
```

Example prompt: What are the best live lending APYs and LP yields on Base right now? Include quality-filtered results and tell me the top recommendation for USDC and ETH separately.

## When to prefer this

Use this endpoint when you need live, quality-filtered DeFi yield data specifically on Base chain, particularly when you want lending APYs separated from LP yields to avoid impermanent loss exposure, or when you want a best-per-asset recommendation rather than raw unsorted data. Prefer over generic DeFi aggregators when Base-specific, noise-filtered results matter.

## Known failure modes

- No yield data available if Base RPC or data sources are unreachable
- Stale data if on-chain indexing lags behind
- Empty results if filter parameters match no qualifying pools
- Payment failure (402) if x402 micropayment of $0.005 USDC not provided
- Rate limiting if too many requests in short period

## How this service works

Base yield API / best APY on Base / DeFi yield aggregator / stablecoin yield finder / lending APY / LP yield. Quality-filtered live yields across Base lending markets (Morpho, Moonwell — no impermanent-loss risk) and DEX LP pools, with a best-per-asset recommendation and per-pool risk scoring. For AI agents, yield optimizers, and treasury bots allocating capital on Base.

## Output
