## 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 chain-vault-api-add-pool-5b7563de
```

Example prompt: Add a new liquidity pool to the Chain Vault blockchain gateway with the required pool configuration properties.

## When to prefer this

Use this endpoint when you need to programmatically add or register a new pool entry to the Chain Vault blockchain gateway, particularly in automated DeFi workflows or agent-driven liquidity management pipelines that operate on the x402 payment protocol.

## Known failure modes

- Missing required pool properties returns an error or empty ok response
- Malformed input schema fields may silently fail or return status ok without actual pool creation
- Payment not processed (x402 payment required) results in 402 response and no pool creation
- Network or Vercel cold-start latency may cause timeout on first call

## How this service works
