# SignalHarness DeFi Staking Projection

> SignalHarness DeFi Staking Projection is a paid API for AI agents from signalharness.ai, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Projects estimated staking returns, APY, and yield outcomes for DeFi staking positions based on caller-supplied parameters

## Facts

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 signalharness-defi-staking-projection-fbb6c41e -d '<json body>'
```

Example prompt: Can you project the staking returns I'd get if I stake 5000 USDC on a DeFi protocol offering roughly 8% APY for 12 months — I want to see the full yield breakdown including any warnings about the estimate?

## When to prefer this

Choose this endpoint when you need a quick, AI-driven DeFi staking yield projection based on parameters you supply directly — particularly useful when you have specific staking amounts, durations, or protocol details and want an instant estimate without connecting to live on-chain data feeds. It is well-suited for scenario planning and advisory use cases where the caller provides context. Prefer live on-chain analytics tools if you need real-time protocol state or verifiable on-chain APY data.

## Known failure modes

- Malformed or empty staking_projection_request string returns an error
- Insufficient or ambiguous input data may produce warnings but still succeed
- Protocol or token not recognized in the request may result in low-confidence projections
- Payment failure via x402 micropayment protocol prevents execution
- Request string exceeding 65536 characters is rejected by schema validation

## Output

Returns a JSON object containing a staking_projection field with yield estimates and forecasted returns, a warnings array highlighting any assumptions or limitations in the projection, an evidence_scope indicating the analysis is based on caller-supplied data, and a full receipt with payment and execution metadata including latency, service version, and a result hash for verification.
