## 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 speraxos-psm-info-api-13486cd2 -d '<json body>'
```

Example prompt: What's the current PSM info for Listadao — pull the peg stability module data including collateral ratios and any relevant parameters from Sperax's DeFi intelligence API.

## When to prefer this

Choose this endpoint when you need on-chain PSM data specifically for the Listadao protocol via a pay-per-request model with no API key setup. Ideal for AI agents with a USDC wallet on Base that need occasional DeFi intelligence without subscription overhead.

## Known failure modes

- Payment failure if x402 USDC payment on Base is not included or insufficient
- HTTP 402 returned if payment is missing
- Empty or malformed request body may return an error
- Protocol data temporarily unavailable if Listadao on-chain data is unreachable
- Network timeout if Base blockchain is congested

## How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

## Output

Returns Peg Stability Module (PSM) details for the Listadao protocol, likely including parameters such as collateral types, ratios, fees, caps, and current utilization relevant to maintaining the stablecoin peg.
