# AgentDiet DeFi Yield Intelligence

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

Returns DeFi yield data and ROI metrics for a specified on-chain asset via a pay-per-call API

## Facts

- Endpoint: GET https://prompt-guard.agentdiet.dev/v1/defi-yield?utm_source=zero.xyz
- Price: $0.015/call
- Payment: x402, MPP
- Status: unknown
- Last checked: 2026-10-20

- Tags: x402
- Canonical page: https://www.zero.xyz/c/agentdiet-defi-yield-intelligence-a499a8df
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_5RWWow84NaI8cfNkkfBVF

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-a499a8df
```

Example prompt: What's the current DeFi yield and ROI proof for ETH right now — fetch the latest on-chain yield intelligence for me.

## When to prefer this

Choose this endpoint when you need fast, distilled on-chain DeFi yield intelligence for a specific asset, especially when paying per-call with USDC via x402 is acceptable. It is suitable for agents that need ROI proof and compression metrics alongside raw yield data, rather than raw blockchain queries or full protocol analytics dashboards.

## Known failure modes

- Missing or invalid 'asset' query parameter returns an error or empty data object
- Unsupported asset identifier results in empty or null data
- Network or upstream data source unavailability returns a non-ok status
- Payment failure (HTTP 402) if USDC micropayment is not completed before the request

## 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 ('ok'), a data object containing yield metrics for the queried asset, and an roi_proof object including a compression_ratio_pct value (e.g. 91.4%), indicating how much information was distilled.
