## 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-address-tabs-counters-1ea52785
```

Example prompt: Using Blockscout, give me the activity summary counts for address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum — how many transactions, token transfers, and internal transactions has it made?

## When to prefer this

Choose this endpoint when you need a quick numeric summary of an address's activity across multiple activity categories without paginating through full lists. It is ideal for dashboards, eligibility checks, or pre-filtering before fetching detailed records. Prefer this over full transaction list endpoints when you only need counts, not the actual records.

## Known failure modes

- Invalid or malformed address_hash_param returns an error or empty response
- Unsupported or incorrect chain_id returns a 404 or chain-not-found error
- Address with zero on-chain activity returns all counts as 0
- Rate limiting may occur under high request volume
- Network-specific endpoints may not be available for all chain IDs

## 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

A JSON object with integer counts for each activity tab of the address: transactions_count, logs_count, token_transfers_count, internal_transactions_count, token_balances_count, validations_count, and withdrawals_count. All fields are numeric and represent total historical counts for that address on the specified chain.
