## 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-getbridgevolume-5f68aed5 -d '<json body>'
```

Example prompt: What's the current cross-chain bridge volume on Arbitrum — pull the latest data from SperaxOS?

## When to prefer this

Use this endpoint when you need on-demand, AI-powered bridge volume data for a specific blockchain without managing API keys — ideal for DeFi agents that can pay per request in USDC via x402 and need chain-level cross-chain activity metrics.

## Known failure modes

- Unsupported or misspelled chain name returns an error or empty result
- Payment of 0.001 USDC via x402 not completed results in HTTP 402 rejection
- Network unavailability causes timeout or 5xx error
- Chain with no recorded bridge activity may return zero or null volume data

## 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 bridge volume metrics for the specified chain, including cross-chain transfer amounts and related DeFi activity data payable in USDC via x402.
