# DeFi Yield & APY Pool Data

> DeFi Yield & APY Pool Data is a paid API for AI agents from defi.memoryapi.org, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Fetches and filters DeFi yield pool data across 19,000+ pools, filterable by chain, project, token symbol, or minimum APY.

## Facts

- Endpoint: GET https://defi.memoryapi.org/x402/defi/yields
- Price: $0.001/call
- Payment: x402

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-memoryapi-org-f5b8a1c0
```

Example prompt: Find me the top DeFi yield pools for USDC on Ethereum with at least 8% APY — I want to compare the best opportunities across projects like Aave and Compound.

## When to prefer this

Use this endpoint when you need to discover, compare, or rank DeFi yield pools at scale across many chains and protocols — especially when filtering by chain, token, project, or APY floor. Prefer this over TVL endpoints when the user cares about yield/APY rather than protocol size.

## Known failure modes

- No pools match the specified filters (empty result set)
- Invalid chain or token symbol returns 400 or empty response
- Minimum APY set too high yields zero results
- Rate limiting or payment failure if x402 payment not properly attached
- Stale or delayed APY data if underlying source hasn't updated recently

## How this service works

DeFi protocol TVL, yield/APY pools, and blockchain chain data powered by DefiLlama. Pay-per-call via x402 micropayments.

## Output

A filtered list of DeFi yield pools from a dataset of 19,000+ pools, each entry including pool name, APY, chain, project, and token symbol, narrowed by any combination of chain, project, token symbol, or minimum APY threshold.
