## 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 m2mcent-zk-otc-settlement-mcp-2f6bef33 -d '<json body>'
```

Example prompt: Submit this data payload through the M2MCent ZK OTC settlement endpoint and get back the transaction hash confirming it was processed on Base L2.

## When to prefer this

Only consider this endpoint if you specifically need to submit payloads through the M2MCent x402 monetized MCP node network with gasless USDC settlement on Base L2. The vague input schema (single 'data' string) and mock-looking example response, combined with a low crawl quality score, suggest limited verifiability. Prefer this over alternatives only if you have confirmed access to the M2MCent ecosystem and need its specific routing or settlement behavior.

## Known failure modes

- Insufficient USDC balance causes payment failure and no transaction hash returned
- Malformed or empty data string results in processing error
- Network congestion on Base L2 may delay settlement confirmation
- Invalid x402 protocol headers cause authentication failure
- Opaque endpoint behavior makes it difficult to diagnose failures beyond success:false

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns a JSON object containing a transaction hash (txHash string) and a boolean success field indicating whether the payload was processed and settled on Base L2.

## Response schema (JSON Schema)
