FAQ

What is the Crius API?

A data API for Robinhood Chain (chain id 4663). It serves real-time and historical token prices, OHLCV candles, trades, holders, pools, launchpad data, security checks and wallet analytics over REST and WebSocket, from Crius' own archive nodes.

Is there a free plan?

Yes. The Free plan includes 1,000,000 credits a month, 10 requests per second and one WebSocket connection, with no card required. Core endpoints such as prices, tokens, trades and candles also work without a key at 2 requests per second per IP.

How fresh is the data?

Each block is decoded as it arrives from our own node, typically within a fraction of a second. Every response includes meta.block and meta.lag_ms so you can see exactly how fresh it is.

Which tokens and DEXs are covered?

Every ERC-20 on Robinhood Chain, every Uniswap v2, v3 and v4 pool (including v4 hooks), launchpads such as Pons, Flap.sh, Bankr, Long.xyz and King of the Markets, LP lockers, and tokenized stocks priced from on-chain pools.

How far back does history go?

To block one of Robinhood Chain. Candles, trades and holder history are available from each token's first block.

What counts as a credit?

Each request costs credits depending on the endpoint, from 1 (prices, token profiles) to 20 (a fresh security simulation). Account API calls are free. Credits reset at the start of each UTC month.

How do I pay?

On-chain on Robinhood Chain in USDG, ETH or WETH through the CriusPayments contract, from the Billing page of the dashboard. 6 months are 10% off and 12 months 20% off. Optional auto-renew uses a price cap you set.

Do you store card details?

No. Payments are on-chain from your own wallet; we never hold funds or payment details.

Can I use the API from a browser?

Yes, with care. Anonymous endpoints work directly. For keyed requests, restrict a key to your site's origin (it becomes read-only) or proxy requests through your backend so the key never reaches the page.

Is the price data financial advice?

No. Data is provided as is for building products and research. Always verify before trading.
