Dome API alternative: where to migrate after the Polymarket acquisition
Dome was a unified API for raw prediction-market data and execution across Polymarket and Kalshi. Polymarket acquired it, and the standalone Dome APIs are sunsetting — Dome's docs point developers to Polymarket's own APIs. This page maps the migration honestly, by job, including where CrowdIntel is the answer and where it isn't.
TL;DR
- •Dome was acquired by Polymarket(announced Feb 2026) and its standalone APIs are sunsetting — Dome's docs direct developers to Polymarket's own APIs. Every job Dome did needs a new home.
- •Split the migration by job: raw prices, candles, order books, and execution → Polymarket's official API; unified Polymarket + Kalshi → Synthesis; wallet analytics, trader PnL, and positions → CrowdIntel.
- •CrowdIntel is the wallet-intelligence layer Dome's raw feeds never computed: 3M+ wallets over 1.7B on-chain fills, resolved-outcome PnL, 8-signal insider scores, funding clusters, and hosted backtests — over REST, MCP, and webhooks.
Why people look for an alternative
When an API you built on gets acquired and wound down, the question isn't “what's the one replacement” — it's “which tool now owns each job I was doing.” Dome bundled three different jobs: raw market data (prices, candlesticks, order books), execution (its Order Router), and wallet analytics (Wallet, PnL, and Positions endpoints). The first two fold neatly into Polymarket's own API — that's where Dome sends you. The third is the gap: Polymarket's official API is execution and market data, not wallet intelligence. If you relied on Dome to know whowas trading and how good they were, that capability doesn't come back through the raw API — it's exactly what CrowdIntel computes.
Side by side
| Criterion | CrowdIntel | Dome API |
|---|---|---|
| Status | Live and independent — Polymarket-focused by design | Acquired by Polymarket (announced Feb 2026); standalone APIs sunsetting — Dome's docs cite an April 28, 2026 end-of-life and point to Polymarket's APIs |
| Core data shape | Wallet intelligence + on-chain forensics | Raw market data + execution across venues |
| Venues | Polymarket only, by design | Polymarket + Kalshi (unified), plus cross-platform sports matching |
| Wallet / trader analytics | 3M+ wallets indexed over 1.7B on-chain fills; 1.5M+ scored with resolved-outcome PnL | Wallet, Wallet PnL (realized-only), and Positions (balance ≥ 10,000 shares) endpoints |
| Insider / coordination analysis | 8-signal suspicion scores, funding-graph clusters, published investigations | Not offered — raw data only |
| Win-rate / PnL methodology | Resolved-outcome PnL + sample-size shrinkage | Realized PnL only |
| Prices / candles / order books | No — read-only intelligence, not a price feed | Yes — order-book snapshots, candlesticks, Binance/Chainlink price history |
| Order placement / execution | No — read-only by design | Yes — Order Router (server-side Polymarket execution) |
| Real-time delivery | Webhooks — whale/insider alerts pushed to your stack | WebSockets — real-time Polymarket order data |
| Interface | REST /api/v1 (OpenAPI 3.1, Bearer auth) + MCP server (16 tools) + webhooks | REST + WebSocket; TypeScript and Python SDKs |
| Hosted backtesting | Yes — Backtest API over resolved history | Raw historical data you backtest yourself |
| Pricing | Free dashboard; API $29–299/mo | Discontinued — migrate to Polymarket's APIs |

Move to CrowdIntel if you used Dome for…
- •Wallet analytics — who's trading, and is their record real, luck, or coordination
- •Trader PnL and positions, but deeper: resolved-outcome PnL, shrinkage win rates, every wallet — not just balances above a 10k-share threshold
- •Feeding a bot or AI agent — REST /api/v1, an MCP server, and webhooks instead of polling
- •Insider scores, funding-graph clusters, and a hosted Backtest API Dome never shipped
Go to Polymarket's API or Synthesis if you used Dome for…
- •Raw prices, candlesticks, order-book snapshots, and trade history → Polymarket's official API
- •Server-side order placement (Dome's Order Router) → Polymarket's official CLOB API
- •One integration spanning Polymarket + Kalshi → Synthesis (synthesis.trade)
Frequently asked
Is the Dome API shutting down?
Effectively, yes. Polymarket acquired Dome (announced February 2026), and Dome's own documentation directs developers to migrate to Polymarket's APIs, citing an April 28, 2026 end-of-life for the standalone Dome APIs. If your integration still points at Dome, every job it did — raw data, execution, and wallet analytics — needs a new home. Verify current timelines on Dome's and Polymarket's own docs, since transition dates can move.
What's the best Dome API alternative?
It depends on which Dome endpoints you used. For raw prices, candlesticks, order books, trade history, and order placement, Polymarket's official API is the direct home — that's where Dome pointed developers after the acquisition. For one integration spanning Polymarket and Kalshi, Synthesis (synthesis.trade) is the closest replacement for Dome's cross-venue shape. For wallet analytics, trader PnL, and positions, CrowdIntel goes deeper than Dome's wallet endpoints and is the piece Polymarket's raw API doesn't replace.
I used Dome's Wallet, PnL, and Positions endpoints — what replaces them?
CrowdIntel. Dome returned realized PnL and positions above a 10,000-share threshold; CrowdIntel indexes every wallet over 1.7B on-chain fills, computes resolved-outcome PnL, shrinkage-adjusted win rates, 8-signal insider scores, and funding-graph clusters, and serves them over a read-only REST API, an MCP server for AI agents, and webhooks. It's the wallet-intelligence layer Dome's raw feeds never computed — and the part Polymarket's execution-and-market-data API doesn't cover.
Does CrowdIntel cover Kalshi the way Dome did?
No — CrowdIntel is Polymarket-only, deliberately. Its intelligence is computed from public on-chain data: 1.7B indexed trades, resolved-outcome PnL, funding-graph clusters, insider scores. Kalshi runs a private ledger with no equivalent public record, so any 'Kalshi wallet intelligence' would be guesswork. If you need unified Polymarket + Kalshi access like Dome offered, Synthesis is the closest one-integration replacement.
Can CrowdIntel replace Dome's Order Router / execution?
No. CrowdIntel is read-only by design — it never custodies funds or places orders. Route execution through Polymarket's official CLOB API (or Synthesis for cross-venue), and use CrowdIntel to decide which trades are worth making. The natural pairing is 'official API to trade, CrowdIntel to decide.'
Bottom line
Send Dome's raw data and execution jobs to Polymarket's official API, and cross-venue coverage to Synthesis. But the wallet intelligence Dome surfaced — trader quality, PnL, coordination — has no replacement in a raw feed. That's the job CrowdIntel is built for, and it goes deeper than Dome ever did.
Migrate the wallet layer
The leaderboards, investigations, and radar are free to browse — no login. Developers: start at the MCP server (from Pro, $29/mo) or the REST API reference (Terminal, $99/mo). See the intelligence-vs-execution pairing for how the two layers fit.
