Quickstart

Create an account. Go to dashboard.crius.sh, enter your email and the one-time code we send you. The free plan needs no card and includes 1,000,000 credits a month.
Create an API key. In the dashboard, open API keys and create a key. Copy the secret straight away: it is shown once, and only a hash of it is stored. Keys look like crs_live_AbCd1234_….
Store the key in an environment variable. Never put it in front-end code or commit it to git.
Terminal window
```
export CRIUS_API_KEY="crs_live_…"
```
Make your first request. Get the price of Charge AI (CHARGE), a token that launched on Pons and graduated to a Uniswap v4 pool:
Terminal window
curl "https://api.crius.sh/v1/robinhood/token/0x7b8892cea949bc60d494681d1bc3ea96071ab0b8/price" \ -H "x-api-key: $CRIUS_API_KEY"
const res = await fetch( "https://api.crius.sh/v1/robinhood/token/0x7b8892cea949bc60d494681d1bc3ea96071ab0b8/price", { headers: { "x-api-key": process.env.CRIUS_API_KEY } }, ); const { data, meta } = await res.json(); console.log(`${data.symbol} = $${data.usd} (block ${meta.block})`);
import os, requests r = requests.get( "https://api.crius.sh/v1/robinhood/token/0x7b8892cea949bc60d494681d1bc3ea96071ab0b8/price", headers={"x-api-key": os.environ["CRIUS_API_KEY"]}, ) body = r.json() print(body["data"]["symbol"], body["data"]["usd"], "at block", body["meta"]["block"])

Read the response. Data is in data; meta tells you the block it was read at and how fresh it is.

{
  "data": {
    "symbol": "CHARGE",
    "token": "0x7b8892cea949bc60d494681d1bc3ea96071ab0b8",
    "usd": 0.00000576413,

  },
  "meta": { "chain": "robinhood", "block": 95503718, "block_age_ms": 1050, "lag_ms": 37 }
}

The response headers tell you your limits: x-ratelimit-remaining, x-credits-cost and x-quota-remaining.
