API quickstart - Noxint Docs

This is not vaporware documentation. The API and MCP server run in production today, serving the chat analyst every answer it gives. Public access opens in beta after launch: key minting and credit packs open with the beta. This page documents the live contract. Launch status tracks what is on today.

The Noxint data API serves the same engine that answers the chat analyst, direct and unfiltered. Every call is one GET request to https://noxint.ai/api/v1, authenticated with a personal key and priced per delivered result. No SDK required, no OAuth dance, no per-venue adapters. Here is a complete first call. It reads the current price of Bitcoin.

curl -H 'Authorization: Bearer nx_your_key' \
  'https://noxint.ai/api/v1/price?id=crypto:bitcoin'

A trimmed response:

{
  "data": {
    "asset_id": "crypto:bitcoin",
    "headline": {
      "usd": 62719.1,
      "return_24h_pct": { "value": 1.8, "pctl": 61 },
      "range_pos_7d_pct": 74.2
    }
  }
}

Notice the shape: the 24-hour return arrives with its own percentile. That is the whole point of this API. Numbers land pre-ranked against their own history, so your agent reasons instead of guessing. The full spec is the data contract.

Get set up

This is the flow once the API beta opens.

Go to noxint.ai, sign in with your wallet, and open the console at /dashboard. Any signed-in account will be able to mint a key. No token balance required: the agent lane is not gated on $NOXINT.

Mint a personal key

Create a personal key from the console. It starts with nx_ and is shown once, at creation. Noxint stores only a hash, so a lost key cannot be recovered, only replaced. Up to 5 active keys per account.

Fund data credits

Data credits pay for delivered results. Credit packs open in the console with the beta and fund your key. Data credits are separate from chat credits and from Holder flow.

Make your first call

Send the price request above with your key in the Authorization header. The X-Credits-Charged response header reports exactly what the call cost. No surprise bills, ever.

Explore before you spend

The API teaches itself. The root, docs, and schema operations are keyless, so a cold-start agent (or you, right now) can read the entire contract with no key and no credits.

curl 'https://noxint.ai/api/v1/docs?section=quickstart'

The resolve, coverage, and usage operations require a key but cost zero credits. resolve turns a ticker into a canonical asset ID, coverage lists what is available, and usage reports your credits and rate limit. Nothing bills until real market data is delivered. See the operations overview for the full set of 23 operations.
