## 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 agentworld-solvscore-tokenized-stock-collateral-underwriting-4253d4b4 -d '<json body>'
```

Example prompt: Run a SolvScore collateral underwriting check on Base for our current AgentWorld simulation — we have 92 registered agents, a treasury balance of 5000 USDC, and I'll send the live agent roster and economy stats.

## When to prefer this

Choose this endpoint when you need on-chain collateral underwriting for tokenized stock positions within the AgentWorld simulation ecosystem on Base, specifically when you have live agent roster data, economy snapshots, and a USDC treasury balance to submit. It is purpose-built for SolvScore-based risk assessment tied to the AgentWorld agent economy, not for generic DeFi collateral checks or off-chain credit scoring.

## Known failure modes

- Missing or malformed agents array causes validation error
- Invalid economy object structure returns 400 bad request
- Treasury balance in wrong format (non-string) may cause parsing failure
- Insufficient USDC balance (< $0.02) causes x402 payment failure
- Base network congestion may delay underwriting response
- Empty agents list may return degenerate or null score
