# AgentDiet DeFi Yield Intelligence Endpoint

> AgentDiet DeFi Yield Intelligence Endpoint is a paid API for AI agents from x402-audit.agentdiet.dev, paid per call via x402 or MPP, $0.015/call, status unknown (last checked 2026-10-20).

Fetches DeFi yield data and on-chain return metrics for a specified asset, returning distilled intelligence with ROI proof.

## Facts

- Endpoint: GET https://x402-audit.agentdiet.dev/v1/defi-yield?utm_source=zero.xyz
- Price: $0.015/call
- Payment: x402, MPP
- Status: unknown
- Last checked: 2026-10-20
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/agentdiet-defi-yield-intelligence-endpoint-e0420d61
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_zSTr7jhN9Jr3h8SbdOuJd

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-endpoint-e0420d61
```

Example prompt: What's the current DeFi yield for USDC right now — pull the on-chain return metrics and show me the ROI proof?

## When to prefer this

Choose this endpoint when you need quick, distilled on-chain DeFi yield data for a specific asset with built-in ROI proof metrics. It is especially useful for agents operating in autonomous DeFi workflows that require micropayment-native (x402 USDC) access without OAuth overhead. Prefer this over generic DeFi aggregators when you need compressed, agent-ready intelligence rather than raw protocol data.

## Known failure modes

- Missing or invalid 'asset' query parameter returns incomplete or empty data object
- Unsupported asset ticker may return empty data with status ok but no meaningful yield figures
- Payment failure (HTTP 402) if x402 USDC payment of $0.015 is not included or rejected
- Network or upstream on-chain data unavailability may result in stale or missing yield data
- Rate limiting if too many calls are made in a short period

## 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 intelligence for the requested asset, and an roi_proof object that includes a compression_ratio_pct metric (e.g. 91.4%) demonstrating the distillation efficiency of the returned data.
