StalkChain API

Live crypto data for your app, bot or spreadsheet.

The same 80 lookups our AI connector uses, as simple web requests: top traders and their wallets, smart-money holders, rug checks, wallet histories and live buys and sells. If you can call a URL, you can use it.

In plain words

Ask a question in code, get a clean answer back

1

You ask

Your code calls a web address, like “top traders this week”, and includes your key so we know it's you.

2

We look it up

StalkChain fetches it live: trades, wallets, holders and prices across seven chains.

3

You get data you can use

A tidy answer (JSON) your bot, dashboard or sheet can read, plus how many credits you have left.

Quickstart

Your first request

  1. 1. Get a key

    Sign in at data.stalkchain.com and create an API key in the dashboard. It starts with sc_. You’ll need credits on the account.

    2. Ask for this week’s top traders

    Pick whatever you’re comfortable with:

    Terminal
    curl "https://data.stalkchain.com/api/v1/tools/stalkchain_fomo_leaderboard?window=7d&limit=5" \
  -H "Authorization: Bearer sc_your_key"

  2. 3. Read the answer

    Your data is under data, and credits.remaining is what’s left on your account. Shortened example:

    Response
    {
  "data": {
    "window": "7d",
    "traders": [
      {
        "rank": 1,
        "handle": "…",
        "pnlUsd": 760210,
        "trades": 80,
        "wallets": { "solana": "AGdt…ii9v", "evm": "0x6434…81a3" }
      }
    ]
  },
  "credits": { "remaining": 374750 },
  "meta": { "tool": "stalkchain_fomo_leaderboard", "durationMs": 412 }
}

Questions

Good to know

What's an API, exactly?
It's a web address your code can call to get data back, instead of a person opening a website. You send a question in a standard format, you get a clean answer your program can use.
Where do I get a key?
Sign in at data.stalkchain.com, open the dashboard and create an API key. It starts with sc_. Keep it private, like a password.
What happens when I run out of credits?
Calls are refused with a 402 status and the code out_of_credits, so nothing is charged. Every successful response also tells you how many credits you have left, in the x-credits-remaining header.
GET or POST?
Either. GET takes the inputs as query parameters (?window=7d&limit=5); POST takes them as a JSON body. They return the same thing.
What does null mean in a response?
That the value wasn't captured. It is never used to mean zero, so you can tell a real 0 from missing data.
Is there an AI version?
Yes. The same data plugs straight into ChatGPT, Claude and Cursor with no code. See the AI page.
