Read a counterparty graph for an address

1Call the graph endpoint

Pass the chain and address. The graph endpoint is C3-metered. Each edge is a counterparty with a direction, volume and, where known, an entity label.

curl https://api.1st-node.com/v1/intel/eth/0x9a..f2/graph \
  -H "Authorization: Bearer sk_live_..."

2Read the labeled edges

The response lists counterparties with direction, volume and cluster-level entity labels plus confidence. Unlabeled edges come back with the raw address.

> { "edges": [
>   { "peer": "0x28..a1", "entity": "Binance",
>     "category": "exchange", "dir": "out",
>     "volume_usd": 412000, "confidence": 0.9 },
>   { "peer": "0x5c..09", "entity": null,
>     "dir": "in", "volume_usd": 88000 } ] }

3Store the graph for reproducibility

Persist the edge list verbatim. Because you own the structured data, the same graph can be re-rendered and audited later without re-querying, and the conclusion stays reproducible.
