## 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 synapse-api-ink-blockchain-latest-block-60d13020 -d '<json body>'
```

Example prompt: What is the latest block on the Ink blockchain right now — can you fetch the current block number, hash, and timestamp?

## When to prefer this

Choose this endpoint when you specifically need the latest block data from the Ink blockchain network and are comfortable with pay-per-call USDC micropayments via the x402 protocol. It is part of the Synapse multi-chain suite covering 57+ networks, so prefer it if you are already using Synapse for other chains or need a unified API across blockchains rather than a dedicated single-chain provider.

## Known failure modes

- Network timeout if Ink RPC node is unreachable
- HTTP 402 payment required if USDC payment not provided via x402 protocol
- Empty or malformed response if Ink network is experiencing issues
- Invalid request body structure causing 400 Bad Request
- Rate limiting if too many calls made in quick succession

## Output

Returns the latest block data from the Ink blockchain network, likely including block number, block hash, parent hash, timestamp, and possibly transaction count or other block header fields.
