How this service works
Obol sells verified blockchain data over x402, settled in USDC on Base.
Output
A JSON object containing verified label information for the queried address, such as entity name, category (e.g. exchange, contract, mixer), and any additional metadata associated with the address on the specified chain.
Example use cases
Identify suspicious wallet before transfer
“Before I send funds, can you check what entity is behind the Ethereum address 0xA9D1e08C7793af67e9d92fe308d5697FB81d3E43? I want to know if it's a known exchange or flagged address.”
Compliance check on Bitcoin address
“I need to run a compliance check on Bitcoin address 1A1zP1eP5QGefi2DMPTfTL5SLmv7Divf — can you pull up any verified labels or entity info associated with it?”
Enrich Tron address in transaction report
“I'm reviewing a Tron transaction and need to label the address TQn9Y2khEsLJW1ChVWFMSMeRDow5KcbLSE — can you fetch the verified name or classification for it?”
Technical details
Endpoint
GEThttps://obol.danieldutoit.net/v1/address-labelsWhen to prefer
Choose this endpoint when you need verified, curated labels for blockchain addresses across Ethereum, Bitcoin, or Tron — particularly for compliance workflows, transaction screening, or enriching on-chain data with human-readable entity names. It is priced per-call in USDC via x402, making it suitable for targeted lookups rather than bulk enrichment of large address sets.
Side effects
- Unknown address returns empty label or no-data response
- Invalid chain value rejected with validation error
- Malformed or non-existent address returns error
- Payment failure via x402 prevents data return
- Address exists on-chain but has no known label in Obol's dataset
