## 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 phantom-api-ink-network-transaction-history-75364f84 -d '<json body>'
```

Example prompt: Pull the last 25 transactions sent from wallet 0xABC...123 on the Ink network, sorted newest first, and include full metadata — skip any zero-value transfers.

## When to prefer this

Use this endpoint when you need historical transaction data specifically on the Ink blockchain network, with support for block-range filtering, category-based filtering, pagination, and optional metadata enrichment. Prefer this over generic block explorers when you need structured, machine-readable output suitable for agent workflows and programmatic analysis at $0.01 per call.

## Known failure modes

- Invalid or missing address fields return an error with no results
- Block range out of bounds or malformed block strings cause query failure
- Unsupported category types may return empty results silently
- Expired or invalid pageKey causes pagination restart or error
- Payment failure via x402 protocol results in 402 response before data is returned
- Network congestion or Ink node unavailability may cause timeouts

## How this service works

Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

## Output

Returns a paginated list of on-chain transactions matching the query filters, including transaction hashes, block numbers, sender/receiver addresses, value, category labels, and optional metadata. A pageKey is included when additional results are available for continued pagination.
