CrowdIntel API

Build Polymarket bots and agents on the deepest data: 1.7B+ indexed on-chain fills, smart-money signals, whale alerts, funding clusters, and hosted backtests — read-only, so your bot keeps execution. Wallet signals, market sentiment, on-chain trades, and sybil clusters over REST, MCP, and webhooks.

Quickstart

Every request needs an Authorization: Bearer cint_api_… header. Responses are snake_case; errors use { error: { code, message, request_id } }; lists return { data, next_cursor }.

curl

curl https://crowdintel.xyz/api/v1/signals/wallet/0xYOUR_WALLET \
  -H "Authorization: Bearer cint_api_xxxxxxxxxxxxxxxxxxxxxxxx"

JavaScript (fetch)

const res = await fetch(
  "https://crowdintel.xyz/api/v1/signals/wallet/0xYOUR_WALLET",
  { headers: { Authorization: `Bearer ${process.env.CROWDINTEL_API_KEY}` } },
);

if (!res.ok) {
  const { error } = await res.json();
  throw new Error(`${error.code}: ${error.message} (${error.request_id})`);
}

const signal = await res.json();
console.log(signal.smart_money_score, signal.confidence);

// Cursor pagination
let cursor = null;
do {
  const url = new URL("https://crowdintel.xyz/api/v1/leaderboards/pnl");
  url.searchParams.set("limit", "100");
  if (cursor) url.searchParams.set("cursor", cursor);
  const page = await fetch(url, {
    headers: { Authorization: `Bearer ${process.env.CROWDINTEL_API_KEY}` },
  }).then((r) => r.json());
  for (const row of page.data) console.log(row.address, row.total_pnl);
  cursor = page.next_cursor;
} while (cursor);

Python (requests)
