📊Data API

Overview

The Data API provides read-only access to query and browse intellectual property assets across the Molecule Protocol. Use these queries to build marketplaces, token screeners, portfolio trackers, and discovery interfaces for decentralized science projects.

Features:

• Query IP-NFTs (Intellectual Property NFTs) and their metadata

• Browse IP Tokens (IPTs) with market data

• Access trading metrics and liquidity information

• Filter, sort, and paginate results

• Build data-driven applications

Common Patterns

Pagination

Use skip and limit for pagination:

// Page 1
{ "limit": 20, "skip": 0 }

// Page 2
{ "limit": 20, "skip": 20 }

// Page 3
{ "limit": 20, "skip": 40 }

Sorting

Sort results by any field:

{
  "sortBy": "createdAt",  // or "mintedAt", "updatedAt", etc.
  "sortOrder": "desc"      // or "asc"
}

Filtering

Filter results by specific criteria:

Filter by owner:

{
  "filterBy": {
    "userId": "0x1234567890123456789012345678901234567890"
  }
}

Filter by chain:

{
  "filterBy": {
    "chainId": 1  // Ethereum mainnet
  }
}

Filter IPTs by IPNFT:

{
  "filterBy": {
    "ipnftId": "0xcaD88677CA87a7815728C72D74B4ff4982d54Fc1_37_1"
  }
}

Error Handling

Status Code	Error	Description
401	Unauthorized	Missing or invalid API key
400	Bad Request	Invalid query syntax or parameters
404	Not Found	Requested resource doesn't exist
500	Internal Server Error	Server error - retry the request

Troubleshooting

401 Unauthorized Error:

• Verify x-api-key header is included

• Check that your API key is valid and not expired

• Ensure no typos in the API key

Empty Results:

• Check filter criteria - may be too restrictive

• Verify the chainId if filtering by chain

• Try removing filters to see all results

GraphQL Errors:

• Check query syntax is valid

• Ensure field names match the schema

• Verify variable types match parameter types
