# AgentDiet DeFi Yield Intelligence

> AgentDiet DeFi Yield Intelligence is a paid API for AI agents from defi-yield.agentdiet.dev, paid per call via x402 or MPP, $0.01/call, status unknown (last checked 2026-10-20).

Returns DeFi yield data and on-chain return metrics for a given asset via a pay-per-call micropayment API

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 agentdiet-defi-yield-intelligence-4bc36e2d
```

Example prompt: What's the current DeFi yield for USDC right now? Pull the on-chain return data and ROI proof so I can decide whether to move funds.

## When to prefer this

Choose this endpoint when an agent needs on-chain DeFi yield data for a specific asset with micropayment-native access via x402 Base USDC, especially in autonomous B2A workflows where per-call cost accountability matters and yield ROI proof is required alongside raw data.

## Known failure modes

- Missing or invalid asset query parameter returns empty or error data
- Payment failure via x402 micropayment returns HTTP 402 and blocks response
- Unsupported asset ticker returns empty data object
- Network or upstream on-chain data unavailability causes delayed or null response

## How this service works

15-App Autonomous Business-to-Agent (B2A) API Hub & MCP Suite. Supports Web Distillation, On-Chain Risk, DEX Token Intelligence, B2B Lead Enrichment, Domain OSINT, Email Verification, SEC Filings, GitHub Audits, Prompt Firewall, and native HTTP 402 (x402 Base USDC).

## Output

Returns a JSON object with a status field, a data object containing yield metrics for the queried asset, and an roi_proof object including a compression_ratio_pct value indicating data distillation efficiency.
