## 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 horizonpulse-defi-yield-pool-rankings-00525a9b
```

Example prompt: Pull up the top-ranked DeFi yield pools right now — I want to see the best stablecoin and single-asset opportunities filtered to pools with at least $10M TVL, sorted by APY.

## When to prefer this

Choose this endpoint when you need a pre-filtered, ranked view of DeFi yield opportunities specifically curated for lower-risk profiles (stablecoin/single-asset, TVL ≥ $10M). It saves the overhead of querying DefiLlama directly and applying your own filters. Prefer it over raw DefiLlama API access when you want an opinionated, agent-ready ranking rather than raw pool data. Best suited for yield discovery, treasury management decisions, and daily yield monitoring workflows.

## Known failure modes

- DefiLlama upstream API unavailability causing stale or missing data
- Empty result set if DefiLlama data feed is temporarily down
- HTTP 402 payment required if x402 payment header is missing or malformed
- Rate limiting or payment processing errors at $0.02 USDC per call
- Network timeouts if the aggregation layer is slow to respond

## How this service works

Pay-per-call APIs for AI agents via x402 on Base: web fetch, HTTP proxy, page extract, and crypto market data.

## Output

A ranked list of DeFi yield pools filtered to TVL ≥ $10M, with preference for stablecoin and single-asset pools. Each entry typically includes pool name, protocol, APY, TVL, and asset/pool type metadata sourced from DefiLlama.
