# x402node LST Rates API

> x402node LST Rates API is a paid API for AI agents from api.x402node.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-27).

Returns aggregated APR, TVL, and pool data for major liquid staking tokens (stETH, rETH, cbETH, sfrxETH, wbETH, osETH, etc.) sourced from DeFiLlama yields.

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 x402node-lst-rates-api-963cf0ab
```

Example prompt: Can you pull the latest APR and TVL for all major liquid staking tokens — stETH, rETH, cbETH, sfrxETH — so I can see which protocol is offering the best staking yield right now?

## When to prefer this

Use this endpoint when an agent needs to compare staking yields across multiple LST protocols in a single call, rather than querying each protocol individually. Ideal for yield optimization, portfolio rebalancing decisions, or DeFi research dashboards that need a live, aggregated snapshot of LST APRs and TVLs.

## Known failure modes

- DeFiLlama upstream data unavailable — stale or empty response
- Payment not included or invalid — 402 Payment Required
- Network timeout fetching live yield data
- Protocol temporarily missing from aggregator feed

## How this service works

Liquid staking and restaking token rates: APR, TVL and pool for major LSTs (stETH, rETH, cbETH, sfrxETH, wbETH, osETH and more) aggregated from DeFiLlama yields. Lets an agent compare staking yields across protocols in one call. Live aggregated DeFi yield data. liquid staking APR, stETH rETH yield, LST rates, restaking Accepts payment on Base or Solana — either network works.

## Output

A list of major liquid staking tokens (LSTs) with their current APR, TVL, and pool details, aggregated from DeFiLlama yield data, enabling direct yield comparison across protocols like Lido, Rocket Pool, Coinbase, Frax, and others.
