## 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-abstract-transaction-history-256ccd3e -d '<json body>'
```

Example prompt: Pull the last 25 transactions involving wallet 0xABC123... on the Abstract network, sorted newest first, and include metadata — skip any zero-value transfers.

## When to prefer this

Choose this endpoint when you need historical transaction records specifically on the Abstract blockchain network and want pay-per-call pricing via x402 without a subscription. It is well-suited for agents needing filtered, paginated transaction lookups with optional metadata enrichment across a defined block range.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Block range parameters out of order or exceeding chain height may return empty results
- Invalid category filter values cause request rejection
- Missing required address fields result in bad request error
- Rate limits or payment failures (x402) block the call
- pageKey from a different query context causes unexpected results

## 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 for the specified address(es) on the Abstract network, including transaction hashes, block numbers, sender/receiver addresses, values, and optionally rich metadata. A pageKey is included for fetching subsequent pages.
