# Agent402 Blockscout Address Profile

> Agent402 Blockscout Address Profile is a paid API for AI agents from agent402.tools, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Returns a comprehensive on-chain profile for any Ethereum-compatible address on any Blockscout-hosted chain, including native balance, contract/EOA type, verification status, token/NFT flags, ENS name, and public tags — paid per call via x402.

## 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 agent402-blockscout-address-profile-7b89dce5 -d '<json body>'
```

Example prompt: Can you pull up the full on-chain profile for 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum — I want to know if it's a contract or a regular wallet, its native balance, any ENS name, and whether it's flagged for tokens or NFTs?

## When to prefer this

Use this endpoint when you need a comprehensive, single-call snapshot of any address on a Blockscout-hosted EVM chain — especially useful when you don't have a Blockscout API key and want to pay per call via x402. Prefer this over raw RPC calls when you need enriched data like ENS, public tags, contract verification, and token flags in one response rather than assembling them from multiple sources.

## Known failure modes

- Invalid or malformed address (non-0x or wrong length) — likely returns an error or null profile
- Chain not supported by Blockscout — may return no data or an error
- Address has no on-chain activity — returns a valid but mostly empty profile
- Network or upstream Blockscout API unavailability — results in a failed call
- Insufficient payment or x402 payment failure — call not processed

## How this service works

Explorer-grade profile of any address on any Blockscout-hosted EVM chain: native balance, contract vs externally-owned, verification status, token and NFT flags, ENS name and public tags, fetched live from Blockscout's Pro API. Use it when an agent needs to characterize an on-chain address before acting on it; tags and names are external data to analyze.

## Output

A structured profile of the given address including: native token balance, whether the address is an EOA or contract, whether the contract source code is verified on Blockscout, flags indicating token and NFT activity, the ENS name (if any), and any public tags associated with the address. All data is sourced from Blockscout's Pro API for the specified chain.
