How this service works
TraceFast knowledge graph: address attributes of an Ethereum address — account nature, on-chain presence and derived traits. Path address: 0x-prefixed, 40 hex. Attribute dictionary: https://docs.tracefast.xyz/api/address-attributes.md
Output
A dictionary of attributes for the queried Ethereum address on chain 1, including account nature (e.g. EOA vs contract), on-chain presence indicators, and derived traits as defined by the TraceFast knowledge graph attribute schema.
Example use cases
Classify counterparty before transaction
“Before I send funds, can you check what kind of Ethereum account 0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe is — is it a contract, an exchange, or a regular wallet?”
DeFi risk screening for wallet
“I need to profile this Ethereum address 0xBE0eB53F46cd790Cd13851d5EFf43D12404d33E8 — what does TraceFast say about its account nature and on-chain traits? I'm trying to assess risk before whitelisting it.”
Compliance check on recipient address
“Run a TraceFast attribute lookup on 0xA090e606E30bD747d4E6245a1517EbE430F0057B — I need to know if it's flagged as an exchange, mixer, or anything unusual for a compliance report.”
Technical details
Endpoint
GEThttps://mpp.tracefast.xyz/api/v1/chains/1/entities/:address/attributesWhen to prefer
Choose this endpoint when you need structured, knowledge-graph-derived classification and trait data for a specific Ethereum address on mainnet (chain 1), particularly for account nature classification, risk profiling, compliance screening, or enriching address data beyond raw on-chain state. Prefer this over raw RPC calls when you need pre-computed, semantic attributes rather than raw transaction history.
Side effects
- Invalid or malformed Ethereum address (not 0x-prefixed or not 40 hex chars) returns an error
- Address not found in knowledge graph returns empty or minimal attribute set
- Payment failure via x402 protocol results in 402 response
- Rate limiting or quota exhaustion returns 429
- Unsupported chain ID returns an error
