Use this file to discover all available pages before exploring further.

The Lasso API is built on REST principles. All requests use HTTPS and return JSON responses. Use Lasso to search for products, enrich partial data into complete records, extract structured data from files, and enhance it with AI — all through a single API.

​
Base URL

All requests contain the following base URL: 
https://hub.banditshq.com/api/v1

​
Quick examples

The fastest way to use Lasso — no setup required: 
curl -X POST "https://hub.banditshq.com/api/v1/search" \
  -H "Authorization: Bearer lasso_..." \
  -H "Content-Type: application/json" \
  -d '{ "query": "Sony wireless earbuds under $200" }'

​
Authentication

To authenticate you need to add an Authorization header with the contents of the header being Bearer lasso_xxxxxxxxx where lasso_xxxxxxxxx is your API Key. 
Authorization: Bearer lasso_xxxxxxxxx
API keys are scoped to a single company. All resources accessed through a key belong to that company. See the Authentication page for more details on key management and security best practices.

​
SDKs

Official SDKs are available for TypeScript and Python. 
npm install @lasso-ai/sdk

import LassoClient from "@lasso-ai/sdk";

const client = new LassoClient({ apiKey: "lasso_..." });

// Search
const results = await client.search({ query: "wireless earbuds" });

// Enrich
const enriched = await client.enrich({
  items: [{ data: { name: "Sony WF-1000XM5" } }],
});

​
Pagination

List endpoints support page-based pagination with page and limit query parameters. The default page size is 25 and the maximum is 100. 
{
  "data": [...],
  "pagination": {
    "page": 1,
    "limit": 25,
    "total": 143
  }
}
See Pagination for details and iteration examples.

​
Webhooks

Configure a webhook_url on search, enrich, or table creation to receive HTTP POST notifications when processing completes. Webhook payloads are signed with HMAC-SHA256 and retried up to 3 times with exponential backoff. See Webhooks for delivery format, signature verification, and retry policy.
