Connect 150+ blockchains, 100+ exchanges, 50+ wallets, and 5,500+ integrations with one client. Real-time, classified, ready to ship in your product.
Free tier · 10K requests/month
Four endpoints, real-time deliveries, and a coverage matrix the rest of the industry would take you years to replicate.
connect() handles wallets, exchanges, and chains in one request. No per-source code in your client.
Trades, transfers, LPs, staking, NFTs, all in the same shape so your downstream code is simple.
Webhooks on chain events, balance changes, and price thresholds. p95 under 200ms.
We ship new chains monthly. If your users hold it, we probably index it.
Address resolution, price feeds, ENS, ABI decoding, pick the pieces you need.
Read-only by design, SOC 2 Type II, HMAC-signed webhooks, scoped tokens per env.
Multi-chain balance, portfolio P&L, and transaction history without writing connectors.
Country-specific tax engines built on top of classified, normalised transaction data.
Show users a portfolio view across the assets they hold off your platform.
Feed agents clean on-chain data. No more LLMs hallucinating swap routes from RPC dumps.
Build on-chain treasury views for finance teams without owning the integration backlog.
Kryptos Connect is the API. The rest of the product (tax, portfolio tracking, accountant workspaces) is built on top of it. You can use Connect standalone to power your own product.
10,000 requests per month, all chains, all integrations. No credit card, no time limit. Paid tiers add higher rate limits, webhooks, and enterprise features.
Balance and trade events are real-time over webhooks. Pull endpoints have sub-second freshness on top chains, with eventual consistency on long-tail chains documented in our status page.
For enterprise customers, yes. If you need a chain or protocol we don't ship today, we can spin up a custom indexer within four weeks for most cases.
Sanctions screening on every wallet hit, with surface flags in the response. Full KYC/AML integrations are roadmap; happy to discuss on a scoping call.
Custom rate limits, SLAs, dedicated indexers, and pricing for high-throughput use cases.
Install the SDK, paste your API key, make one call. The response includes balances, transactions, classifications, and price data.
