Label a wallet with entity data
Raw addresses tell you nothing on their own. The labels endpoint returns the entity a cluster is attributed to, its category and a confidence value you can threshold. Store the label with the address so the same conclusion is reproducible later.
- A live API key (Bearer token) with a positive credit balance
- The address you want to label and its chain (eth, tron or btc)
1Call labels on the address
Pass the chain and address. The labels endpoint is C3-metered, so a small per-call credit cost applies.
curl https://api.1st-node.com/v1/intel/eth/0x9a..f2/labels \ -H "Authorization: Bearer sk_live_..."
2Read the entity, category and confidence
The response carries a cluster-level entity attribution, its category and a confidence value. Treat the entity as a cluster attribution, not a named individual.
> { "entity": "Binance", "category": "exchange",
> "confidence": 0.9 }3Threshold and persist the label
Apply your own confidence floor: accept high-confidence labels automatically, flag borderline ones for review. Persist the entity, category and confidence verbatim next to the address so the attribution is reproducible.
4Combine with AML risk on the same key
Because intelligence and AML share one API key, you can pair the label with a risk-score call to turn an entity attribution into an allow, review or block decision.
curl https://api.1st-node.com/v1/aml/eth/0x9a..f2/risk \ -H "Authorization: Bearer sk_live_..."
Preguntas frecuentes
Does a label identify a real named person?
No. Labels are cluster-level attributions with a confidence value — they name the entity a cluster is associated with, not an individual owner.
What does a label call cost?
Labels is a C3 primitive — metered per call, cheaper than a per-seat dashboard license. You store the response yourself, so the label is yours to reuse.
