TraceFast Address Relations
x402
TraceFast Address Relations is a paid API for AI agents from mpp.tracefast.xyz, paid per call via x402, $0.025/call, status unknown (last checked 2026-10-19).
Returns the current knowledge-graph relations of an Ethereum address — either as subject (what it points at) or as object (who points at it), covering proxy targets, beacon reads, admin links, delegations, and lending market listings.

How this service works
TraceFast knowledge graph: the relations an address holds now — which implementation a proxy points at, which beacon it reads, who administers it, where an account has delegated, which lending market lists a token — as the subject (`direction=subject`: what it points at, default) or as the object (`direction=object`: who points at it). Path: address. Query: direction, attributeId, limit, cursor (see docs). Docs: https://docs.tracefast.xyz/api/address-relations.md
Output
A paginated list of relation records for the specified Ethereum address, each describing a directed edge in the knowledge graph — including the relation type (e.g. proxy implementation, beacon, admin, delegation, lending market listing), the counterparty address, and supporting attribute IDs. Includes a cursor for fetching subsequent pages.
Example use cases
Resolve proxy contract implementation
“What is the current implementation contract that the proxy at 0x1234abcd...5678 points to on Ethereum mainnet? I want to know the live target, not a historical one.”
Find all delegators to an address
“Which addresses have currently delegated to 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum? Show me the object-direction relations so I can see who points at it.”
Audit lending market token listings
“I need to know which lending markets currently list the token at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 — pull the subject-direction relations from TraceFast and show me the full list.”
Technical details
Endpoint
GEThttps://mpp.tracefast.xyz/api/v1/chains/1/entities/:address/relations?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to enumerate all current on-chain relations of a specific Ethereum address in either direction — especially for resolving proxy implementations, tracing admin hierarchies, finding delegation targets, or discovering which DeFi markets reference a token. Prefer it over raw RPC calls or block explorers when you need structured, pre-indexed graph edges without writing custom event parsing logic. The subject/object directionality and attributeId filter make it more targeted than a generic counterparty lookup.
Side effects
- Invalid or malformed Ethereum address returns a 400 error
- Unknown address with no recorded relations returns an empty list
- Invalid direction parameter value causes a 400 bad-request error
- Expired or invalid cursor returns a pagination error
- Rate limit or payment failure (x402) blocks the request
- Network or chain indexing lag may mean very recent state changes are not yet reflected
