## 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 dexl-agents-marketplace-probe-03213079 -d '<json body>'
```

Example prompt: Before I start making paid calls on the DexL Agents marketplace, probe the marketplace endpoint to find out what payment scheme and EVM network it uses so I know how to configure my x402 wallet.

## When to prefer this

Use this endpoint when you need to discover the payment scheme and settlement network of the DexL Agents marketplace before initiating paid calls, or when debugging x402 payment negotiation failures. It is a lightweight probe with no side effects, making it ideal for pre-flight checks in agent workflows that depend on correct payment configuration.

## Known failure modes

- Service unreachable returns network error or timeout
- Malformed input body returns 400 validation error
- Unsupported bodyType enum value causes rejection
- Missing required 'type', 'method', or 'bodyType' fields returns 422
- Marketplace temporarily unavailable returns 503

## How this service works

A deliberately cheap paid call, for checking that your wallet, network and x402 client actually work against this gateway before you spend more on a real product. It settles a real payment and echoes back what we saw: network, scheme, amount and your address.

## Output

Returns a JSON object with an 'ok' boolean indicating availability, a 'scheme' string (e.g. 'upto') describing the supported payment negotiation scheme, and a 'network' string (e.g. 'eip155:8453' for Base) identifying the EVM chain used for settlement.
