Getting started

Quickstart

Five minutes from sign-up to your first PRISM dimensional analysis. Pick a language and follow the steps.

1. Get an API key

Sign in at prism.zi-find.com, head to Settings → API keys, and click Create key. Keys are scoped per-environment (test / live) and rotatable from the same screen.

2. Install the SDK (optional)

SDKs are thin wrappers around the HTTP API. Skip if you'd rather use bare HTTP.

BASH

"tk-cmt"># Python
pip install prism-sdk

"tk-cmt"># JavaScript / TypeScript
npm install @prism/sdk

3. Make your first call

The Hallucination Guard endpoint is the simplest cold start. Paste any AI-generated text plus your source material and watch the cross-walking work.

Python

PYTHON

class="tk-kw">from prism class="tk-kw">import Prism

prism = Prism(api_key=class="tk-str">"sk_test_...")

result = prism.hallucination_guard.check(
    text=class="tk-str">"Per Smith v. Jones, 142 F.3d 891 (9th Cir. 2018), the doctrine applies...",
    sources=[class="tk-str">"...intake notes...", class="tk-str">"...exhibit B..."],
    domain=class="tk-str">"legal",
)

print(result.flagged_text)
print(result.risk_score)

JavaScript

JAVASCRIPT

import { Prism } from "@prism/sdk";

const prism = new Prism({ apiKey: process.env.PRISM_API_KEY });

const result = await prism.hallucinationGuard.check({
  text: "Per Smith v. Jones, 142 F.3d 891 (9th Cir. 2018), the doctrine applies...",
  sources: ["...intake notes...", "...exhibit B..."],
  domain: "legal",
});

console.log(result.flagged_text);
console.log(result.risk_score);

cURL

BASH

curl https://api.prism.dev/v1/hallucination-guard/check \
  -H "Authorization: Bearer $PRISM_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "text": "Per Smith v. Jones, 142 F.3d 891 (9th Cir. 2018)...",
    "sources": ["...intake notes...", "...exhibit B..."],
    "domain": "legal"
  }'

4. Read the response

Every endpoint returns JSON. Citation cross-walking returns flagged text plus a structured array:

JSON

{
  "tk-key">"flagged_text": "Per Smith v. Jones, 142 F.3d 891 (9th Cir. 2018) [verify], the doctrine applies...",
  "tk-key">"flags": [
    {
      "tk-key">"type": "case_citation",
      "tk-key">"raw": "Smith v. Jones, 142 F.3d 891 (9th Cir. 2018)",
      "tk-key">"in_sources": false
    }
  ],
  "tk-key">"risk_score": 0.72,
  "tk-key">"domain": "legal"
}

5. Wire into your product

Most integrators run their model output through Hallucination Guard before showing it to the user, adding ~150ms to the path and zero false-positive risk because existing [verify] markers are idempotent. See the Hallucination Guard reference for the full surface.
