# DeFi Yield Opportunity Radar

> DeFi Yield Opportunity Radar is a paid API for AI agents from 6xrkjcfa3yrzvefcpvanurzou4.srv.us, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Returns live TVL, yield metrics, protocol counts, and audit coverage per blockchain chain to help agents identify where liquidity is concentrated and what it is paying

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-opportunity-radar-42e464e8
```

Example prompt: Scan the DeFi yield landscape for Ethereum, Arbitrum, and Optimism — I want to see live TVL, how each chain's liquidity has moved over the last 7 and 30 days, the trend direction, and how much of each chain's protocols are audited.

## When to prefer this

Use this endpoint when an agent needs to compare DeFi liquidity health and yield opportunity across one or more blockchains before deciding where to deploy capital. It is the right choice when the question is 'where is the liquidity and what is it paying' — covering TVL magnitude, momentum, protocol depth, and audit coverage in a single call. Prefer this over raw DefiLlama API calls because it requires no API key and is payable per-call via x402 with no account setup.

## Known failure modes

- Unknown or misspelled chain name returns empty or error response
- DefiLlama upstream API outage causes stale or missing data
- Requesting too many chains at once may time out or return partial results
- Chain with no indexed protocols returns zeroed metrics
- Payment not processed (x402 flow failure) blocks the response

## How this service works

Paid DeFi yield and liquidity opportunity radar (cycle 218, x402 $0.01) - GET ?chain=<CHAIN> OR ?chains=<A,B,C> OR ?sample=1|2|3 OR POST application/json {chain|chains}. KEYLESS DefiLlama public API (api.llama.fi) -- no key, no account, no signup. Answers WHERE IS THE LIQUIDITY AND WHAT IS IT PAYING, the question a yield-seeking buyer agent asks before it moves a token: live TVL per chain, 7-day and 30-day TVL change, TVL trend direction, the number of live protocols, the share of AUDITED...

## Output

A structured report per queried chain containing: current total value locked (TVL), 7-day TVL change, 30-day TVL change, TVL trend direction (growing/shrinking/stable), count of live DeFi protocols, and the share of those protocols that have been audited — giving an agent a complete liquidity and safety picture before moving capital.
