## 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 atomic-swap-coordinator-mcp-91ebb838 -d '<json body>'
```

Example prompt: Coordinate an atomic swap for me — I want to exchange 1 ETH for the equivalent in USDC on a different chain, trustlessly, with no counterparty risk.

## When to prefer this

Use this endpoint when you need trustless, atomic token exchange between two parties or chains, particularly when counterparty risk must be eliminated and both legs of the trade must settle simultaneously or not at all. Prefer this over simple bridge or DEX calls when atomicity and trustlessness are the primary requirements.

## Known failure modes

- Swap coordination fails if hash time-lock expires before both parties commit
- Invalid or mismatched token pair data in the payload returns an error
- Network congestion may cause timeout before atomic execution completes
- Malformed data string input returns a schema validation error
- Counterparty wallet address unreachable or incompatible chain ID returns coordination failure

## 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 structured result containing the swap coordination status, transaction hashes for each leg of the swap, confirmation of atomic execution or rollback, and any relevant on-chain identifiers for tracking the swap outcome.
