Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability base-to-polygon-relayer-mcp-7db8d93a -d '<json body>'
```

Example prompt: Can you relay this transaction data from Base to the Polygon network for me? Here's the payload I need bridged cross-chain.

## When to prefer this

Choose this endpoint when you need to programmatically relay or bridge transactions and messages specifically between the Base and Polygon blockchain networks in an automated or agentic workflow, particularly when a pay-per-call model is preferred over managing your own relayer infrastructure.

## Known failure modes

- Invalid or malformed data payload returns an error response
- Network congestion on Base or Polygon may cause relay delays or timeouts
- Insufficient funds or gas on destination chain may cause failed relay
- Cross-chain message size limits exceeded
- Payment of 0.2 USDC not fulfilled results in 402 Payment Required

## 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 relay confirmation including the status of the cross-chain message or transaction, along with relevant transaction identifiers or hashes confirming the bridging operation between Base and Polygon.
