# DeFi Strategy Verdict

> DeFi Strategy Verdict is a paid API for AI agents from defiverdict.hergertsynthora.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Evaluates a DeFi yield, LP, or staking strategy for real risk by checking smart contracts, APY sustainability, and impermanent loss risk, then returns a cryptographically signed execute/monitor/avoid verdict.

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-strategy-verdict-c3b6c495 -d '<json body>'
```

Example prompt: Can you evaluate whether I should put money into the Aave USDC pool at 0x1234abcd... for 30 days — the APY is 12.5% and TVL is $5 million — and tell me if I should execute, monitor, or avoid it?

## When to prefer this

Use this endpoint when you need a structured, cryptographically attested risk verdict on a DeFi strategy before committing funds — especially when smart contract risk, APY sustainability, and impermanent loss are all relevant factors. Prefer this over generic sentiment or news APIs when you need a quantitative, signed risk recommendation specific to on-chain DeFi pools.

## Known failure modes

- Invalid or unrecognized pool address returns error
- Unknown protocol name causes evaluation failure
- APY or TVL values outside plausible ranges may be rejected
- Network unavailability of on-chain data sources can delay or fail the response
- Missing required fields (protocol, pool_address, apy_pct, tvl_usd, duration_days) returns validation error

## How this service works

Evaluates any yield/LP/staking strategy: APY+TVL auto-fetched, risk scoring, verdict.

## Output

Returns a signed verdict (execute, monitor, or avoid) along with a breakdown of smart contract risk, APY sustainability assessment, and impermanent loss risk for the specified DeFi strategy. The verdict is Ed25519-signed for tamper-proof authenticity.
