Example use cases
Example prompt
“What's the label and entity name for the wallet address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — is it a known exchange, protocol, or named entity?”
Technical details
Endpoint
POSThttps://wallet-labels-mcp.mtree.workers.dev/v1/wallet/labelsWhen to prefer
Choose this endpoint when you need to identify, label, or enrich a specific blockchain wallet address with human-readable entity names and provenance metadata, especially in agentic workflows requiring machine-readable output. Particularly useful when ENS resolution alone is insufficient and you need entity-level labels with sourced evidence.
Side effects
- Unknown or unlabeled address returns empty or null label fields
- Invalid address format returns a 400 error
- Payment not included or invalid x402 payment header returns 402 Payment Required
- Address not found in the label database returns a 404 or empty result
- Rate limiting or quota exceeded returns a 429 error
