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.
Example use cases
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.”
Technical details
Endpoint
POSThttps://stablecrypto.dev/api/alchemy/transfers/asset-transfersWhen to prefer
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.
Side effects
- 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
