Build crypto-native products without writing connectors for the long tail of integrations. Kryptos handles the data plumbing so your team ships features, not parsers.
Free tier · 10K requests/month · No credit card
We've spent years building connectors for the integrations you'd otherwise write yourself. You get the unified API, we keep the chains updated.
connect(), tax(), portfolio(), positions(). Four endpoints cover the workflows most crypto-native apps need.
Webhooks on every chain event, sub-second latency on price and balance updates, no polling required.
Trades, swaps, LP enter/exit, staking rewards, airdrops. We label them in the response so you don't write rules.
Reuse the same address-resolution and price-feed primitives that power our consumer apps.
Strongly typed clients with retries, pagination, and rate-limit handling baked in. Open source on GitHub.
Read-only API keys, signed webhook deliveries, scoped tokens per environment. Production-grade from day one.

Multi-chain balance, portfolio P&L, transaction history, and tax exports inside your wallet UI without writing chain-specific code.
Skip building connectors for 5,500+ exchanges. Pull normalised transactions, ship country-specific reports.
Give your users a real portfolio view across the assets they hold elsewhere, not just on your platform.
Feed AI agents clean, classified on-chain data. No more LLMs hallucinating swap routes from raw RPC dumps.
Sign up for a free account, create a project from the dashboard, and your API key appears in seconds. The free tier covers 10K requests per month, no credit card needed.
Free tier: 60 requests per minute. Paid tiers go up to 5,000 RPM. Rate-limit headers ship with every response so your client can self-throttle.
Yes. Subscribe to any combination of chain events, balance changes, or price thresholds. Deliveries are HMAC-signed and retried with exponential backoff.
Yes, under the standard API terms. Resale of raw data is restricted; building products on top of it (wallets, tax apps, analytics) is what we exist for.
99.95% uptime SLO across all paid tiers, with monthly status reports. Status page at status.kryptos.io includes a JSON feed for your monitoring.
10K requests per month, all chains, all integrations. No credit card.
One call connects wallets and exchanges. Three more get you a tax report, a portfolio, and DeFi positions. That's the API surface.
// One API for all of crypto finance
const data = await kryptos.connect({
exchanges: ["binance", "coinbase"],
wallets: ["0x8a2f...3b7c"],
chains: ["ethereum", "solana"],
});
// Normalised, classified, production-ready
const tax = await kryptos.tax(data, "US");
const folio = await kryptos.portfolio(data);
const defi = await kryptos.positions(data);
// → 150+ blockchains · 100+ exchanges
// → 5,500+ integrations · One format
// → You build. We handle the data.
