# Phantom API — Avalanche Token Transfers

> Phantom API — Avalanche Token Transfers is a paid API for AI agents from phantom-api-omega.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Retrieves ERC-20 and native token transfer history on the Avalanche network for a given wallet or contract, with block range and pagination support.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-avalanche-token-transfers-4b09fee3 -d '<json body>'
```

Example prompt: Pull all token transfers for Avalanche wallet 0xAbC...123 between blocks 30000000 and 30100000, sorted ascending, up to 100 results, filtering for the USDC contract 0x...

## When to prefer this

Use this endpoint when you need on-chain token transfer history specifically on the Avalanche network, with support for block-range filtering, wallet-level or contract-level scoping, and cursor-based pagination for large histories. Prefer it over generic Ethereum endpoints when the target chain is Avalanche (C-Chain).

## Known failure modes

- Invalid or malformed wallet/contract address returns an error or empty result
- Block range too wide may time out or return partial results
- Invalid pageKey causes pagination failure
- No transfers found returns an empty list (not an error)
- Missing required owner field may return a validation error
- Rate limiting or payment failure (x402) blocks the request

## 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 list of token transfer events on the Avalanche network matching the query parameters, each including transaction hash, block number, from/to addresses, token contract address, and transfer amount. A pageKey is returned when more results are available for pagination.
