Query Console

The lookup pipeline

From an address to useful context

A single request turns an opaque blockchain identifier into structured, readable intelligence.

  1. Input / 01

    Submit a crypto address

    Choose a network or let CryptoLabel detect it from a valid Bitcoin, Tron, or Ethereum address.

  2. Resolution / 02

    Resolve its on-chain context

    The lookup normalizes the address, identifies its account type and blockchain model, and maps the known entity.

  3. Output / 03

    Receive every known label

    One JSON response provides readable attribution, label provenance, detection method, status, and an explorer link.

Network coverage

Three chains. One interface.

Auto-detect a supported address or choose its network explicitly. Every lookup returns the same predictable response structure.

01

Bitcoin

Resolve known Bitcoin wallets and services from 1, 3, and bc1 address formats.

Ethereum

Identify externally owned accounts, contracts, entities, and attributed labels.

Account-based
Indexed 03

Tron

Look up T-addresses with the same normalized response model used across the API.

What you receive

Useful data, not another opaque score

CryptoLabel returns the fields needed to display, analyze, and review an address with its attribution intact.

01

Structured response

A stable model for every supported chain

Build once against normalized query, address, entity, and labels objects instead of maintaining a different integration for each network.

02

Label intelligence

Context that remains inspectable

Review readable categories together with source type, detection method, and status when an attribution needs to be understood or verified.

03

Built to integrate

Useful in analytics, explorers, and investigations

Enrich datasets, add readable context to address pages, or inspect known services and attributed label categories without an authentication flow.
