Comparison

Nansen vs SmartMoneyAPI

Nansen and SmartMoneyAPI solve different problems. Nansen is a data and research platform you read. SmartMoneyAPI is a pre-trade confirmation layer your bot calls before it enters — one request returns CONFIRM, REDUCE, or SKIP. This page is an honest look at when to use which.

Who each is for

Nansen. Nansen is a wallet-labeling and on-chain analytics platform. Investors use it to follow labeled 'smart money' wallets, track token flows, and screen on-chain activity through curated dashboards.

SmartMoneyAPI. A decision-support API for automated crypto strategies. Your bot already has a candidate direction; one call to /v1/confirm checks it against derivatives, funding, open interest, liquidations, whale consensus and on-chain context, then returns a single action your code can branch on. It does not place orders — you stay in control of execution and risk.

Integration weight	You assemble & interpret the data	Single HTTP call, no data plumbing

Descriptions of Nansen are our neutral summary of a third-party product and may change; check their site for current capabilities. This is not a claim that SmartMoneyAPI is better overall — it is a different, lighter, decision-focused tool.

The honest wedge

Use Nansen for research — to study the market, form a thesis, and decide what to build. Use SmartMoneyAPI when your bot needs CONFIRM / REDUCE / SKIP in one call at the moment of entry. They are complementary: research the edge with a platform like Nansen; gate each live entry with a confirmation call. If you only need a decision at trade time, you don't need to assemble and interpret a full analytics suite yourself.

What the confirmation call looks like

Your strategy produces a candidate direction; this single call validates it before you send the order.

confirm.py

import os, requests

r = requests.get(
    "https://api.smartmoneyapi.com/v1/confirm",
    params={"symbol": "BTC", "direction": "long", "source": "my-bot"},
    headers={"X-API-Key": os.environ["SMA_API_KEY"]},
    timeout=10,
)
sig = r.json()

if sig["action"] == "CONFIRM":
    qty = 0.01 * sig["size_mult"]   # scale by suggested multiplier
    # ... your code places the order
elif sig["action"] == "REDUCE":
    pass  # trade smaller or wait for a cleaner setup
else:  # SKIP
    pass  # market context does not support this trade

action is CONFIRM, REDUCE, or SKIP; confidence is HIGH or MEDIUM; size_mult is a 0.0–1.5 suggested size multiplier; reasons explains the call. Full field reference in the API docs.
