# Alchemy Asset Transfers

> Alchemy Asset Transfers is a paid API for AI agents from stablecrypto.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Retrieves on-chain asset transfer history for a given address, including ERC-20, ERC-721, ERC-1155, and native ETH transfers across EVM networks

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 alchemy-asset-transfers-74997783 -d '<json body>'
```

Example prompt: Show me all ERC-20 and external ETH transfers received by wallet 0xABC...123 on eth-mainnet from block 0x1000000 to latest, sorted descending, and include metadata.

## When to prefer this

Use this endpoint when you need structured, filterable on-chain transfer history for a specific wallet address across EVM-compatible networks via Alchemy's API. Prefer this over raw RPC calls when you need category-based filtering (ERC-20, ERC-721, internal, etc.), block range filtering, and pagination support in a single call. Best suited for wallet analytics, portfolio history, audit trails, and DeFi activity tracking.

## Known failure modes

- Invalid or unsupported network slug returns an error
- Missing required fields (network, category) returns a 400-level error
- Invalid block hex strings may cause query failure
- Empty result set if no transfers match the filter criteria
- Rate limiting or payment failure returns a 402 or 429 error
- Invalid address format may return no results or an error
- pageKey expiry may cause pagination to fail

## How this service works

Pay-per-request access to CoinGecko, DefiLlama, Alchemy, and Etherscan APIs. No auth, no subscriptions.

## Output

Returns a paginated list of asset transfers matching the query, including transfer type, token contract, amount, from/to addresses, block number, transaction hash, and optionally metadata such as token name and decimals. The response may include a pageKey for fetching subsequent pages.
