Quickstart

Get from zero to your first reputation query in under 5 minutes.

1. Get an API Key

1. Go to portal.crowdproof.id
2. Connect your wallet (MetaMask, WalletConnect, Coinbase Wallet, or Rainbow)
3. Navigate to API Keys in the sidebar
4. Click Create API Key — copy the key immediately (it's only shown once)

Your API key will look like: did_live_abc123...

tip

All API requests require the X-API-Key header. The only public endpoints are /health, /api/v1/identity/register, and /swagger.

2. Install an SDK

TypeScript

npm install @decentra-id/sdk

import { DecentraID } from "@decentra-id/sdk";
const client = new DecentraID({ apiKey: "did_live_...", network: "mainnet" });

Python

pip install decentra-id

from decentra_id import DecentraID
client = DecentraID(api_key="did_live_...", network="mainnet")

Go

go get github.com/crowdpay/crowdproof-go

client := decentraid.NewClient("did_live_...", decentraid.WithNetwork("mainnet"))

C#

dotnet add package DecentraID.SDK

var client = new DecentraIDClient(new DecentraIDConfig { ApiKey = "did_live_...", Network = "mainnet" });

cURL

curl https://crowdproof-api.azurewebsites.net/api/v1/reputation/0x1234.../scores \
  -H "X-API-Key: did_live_..."

3. Query Your First Score

TypeScript

const scores = await client.reputation.getScores("0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045");

for (const s of scores) {
  console.log(`${s.category}: ${s.score}/1000 (${s.tier})`);
}

Python

scores = client.reputation.get_scores("0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045")

for s in scores:
    print(f"{s['category']}: {s['score']}/1000 ({s['tier']})")

cURL

curl https://crowdproof-api.azurewebsites.net/api/v1/reputation/0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 \
  -H "X-API-Key: did_live_..."

Response

{
  "address": "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045",
  "scores": [
    { "category": "DEFI_LENDING", "score": 742, "confidence": 0.91, "tier": "High" },
    { "category": "GOVERNANCE", "score": 890, "confidence": 0.95, "tier": "Very High" }
  ]
}

4. Generate a ZK Proof

Prove a score exceeds a threshold without revealing the actual score:

const proof = await client.proofs.generate({
  subject: "0x1234...",
  claim: "score_above_threshold",
  threshold: 700,
  category: "DEFI_LENDING",
});

const result = await client.proofs.verify(proof.proofData);
console.log(result.valid); // true

5. Set Up Webhooks

Receive push notifications when scores change:

curl -X POST https://crowdproof-api.azurewebsites.net/api/v1/webhooks \
  -H "X-API-Key: did_live_..." \
  -H "Content-Type: application/json" \
  -d '{"url": "https://your-app.com/webhooks/crowdproof"}'

caution

Save the secret from the response — it's only shown once. Use it to verify HMAC-SHA256 webhook signatures.
