# Blockscout Advanced Filters – Multichain Transaction Search

> Blockscout Advanced Filters – Multichain Transaction Search is a paid API for AI agents from api.blockscout.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-12).

Queries filtered blockchain transactions, token transfers, and internal transactions across a specific chain using advanced criteria like address, token, method, amount, and time range

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 blockscout-advanced-filters-multichain-transaction-search-6c2448fb
```

Example prompt: Can you pull up all token transfers from wallet 0xABC123 on Ethereum mainnet (chain ID 1) in the last 30 days, filtered to only include USDC transfers?

## When to prefer this

Use this endpoint when you need granular, multi-criteria filtering of on-chain transactions across specific blockchains supported by Blockscout — particularly when you need to combine filters like address, token contract, method name, amount range, and time window simultaneously. Prefer this over basic block explorers when you need programmatic, cross-chain transaction search with advanced filter combinations.

## Known failure modes

- Invalid chain_id returns error or empty results
- Malformed address hashes return 400 or empty items array
- Overly broad filters may return large paginated results requiring cursor navigation
- Unsupported chain IDs not indexed by Blockscout return errors
- Invalid date format in age_from/age_to causes query failure
- Payment failure (x402) blocks access if USDC balance insufficient

## How this service works

Explore crypto activities with Blockscout's multichain search. Find transactions, addresses, tokens, and dapps across top blockchain networks — your go-to explorer for cross-chain blockchain data

## Output

Returns a paginated list of transactions/token transfers matching the filters, each including hash, from/to addresses, value, fee, method called, status, timestamp, block number, token details, and transfer indices. Also returns applied search parameters and next-page cursor for pagination.
