# DeFi Yield Opportunities by Chain

> DeFi Yield Opportunities by Chain is a paid API for AI agents from x402-agent-store.rileycraig14.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).

Returns top DeFi yield opportunities filtered by chain and minimum TVL, including APY, pool, project, and stablecoin info sourced from DefiLlama

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 defi-yield-opportunities-by-chain-67ebe518
```

Example prompt: Show me the top 15 DeFi yield pools on Arbitrum with at least $2 million TVL — stablecoins only — sorted by APY.

## When to prefer this

Use this endpoint when an agent needs live, ranked DeFi yield data sourced from DefiLlama with chain-level filtering and TVL thresholds. Prefer over generic crypto APIs when the goal is specifically yield/APY discovery across DeFi protocols, especially when stablecoin pool filtering or TVL-based screening is needed.

## Known failure modes

- Invalid chain name returns empty results or error
- min_tvl too high may return zero pools
- top parameter exceeding 50 is capped or rejected
- DefiLlama upstream unavailability causes request failure
- Malformed query parameters return 400 error

## How this service works

Current top DeFi yield opportunities filtered by chain and minimum TVL. Returns pool, project, chain, APY (base + reward), TVL, and stablecoin flag, sorted by APY. Sourced live from DefiLlama with attribution. For agents scanning yield opportunities.

## Output

A JSON object containing a count and an array of pools, each with pool name, project, chain, base APY, reward APY, total APY, TVL in USD, and a stablecoin flag, plus a source attribution to DefiLlama. Results are sorted by APY descending.
