# YieldSignal WETH Base Durability

> YieldSignal WETH Base Durability is a paid API for AI agents from yieldsignal.vercel.app, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-29).

Returns what fraction of WETH lending APY on Base survives if incentive programs end, decomposing yield into organic vs incentive-driven components across major protocols.

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 yieldsignal-weth-base-durability-0aaf2a26
```

Example prompt: How much of the current WETH lending APY on Base would survive if all incentive programs stopped tomorrow — break it down by protocol and tell me what's organic vs incentive-driven.

## When to prefer this

Use this endpoint when you need to assess the sustainability of WETH lending yield specifically on Base — particularly before committing capital, during incentive program changes, or when comparing organic yield quality across protocols. Prefer this over generic APY endpoints when the distinction between real yield and temporary incentives matters to your decision.

## Known failure modes

- On-chain data temporarily unavailable causing stale or missing protocol readings
- Protocol not yet covered returns null or partial data for that venue
- Network congestion causes slow response or timeout
- Incentive decomposition unavailable for a specific protocol due to unverifiable source

## How this service works

How much of the WETH lending APY on Base survives if incentives stop — same contract as the USDC durability route, for WETH. Undecomposable sources are named, never assumed incentive-free. Stress test of current readings, not a date forecast. Verified per-asset accuracy is free at /accuracy.json; raw on-chain attestations at /track-record.

## Output

A breakdown of WETH lending APY on Base showing what fraction is organic (incentive-free) versus incentive-driven, with named yield sources per protocol, a durability score or percentage, and stress-test output reflecting current on-chain readings. Undecomposable sources are explicitly named rather than assumed organic.
