How to start developing on Cardano using Tangocrypto API

What is Tangocrypto?

  • There’s no way to access the information on a blockchain without using a node or an API provider.
  • You will have to start creating the infrastructure instead of focusing on your products and business.
  • In-house infrastructure doesn’t scale automatically when user demand increases.
  • There is a high learning curve, a broader error surface and an increase in cost when building integrations with several API services from multiple providers.
  • Ship products faster and validate business ideas.
  • Use one platform to fetch, submit and listen to on-chain information, mint tokens, store files and process payments.
  • Grow their user base by relying on an elastic infrastructure capable of handling spikes in consumption without downtime.
  • Reduce cost on engineering and infrastructure operations.
  • Notify (Webhooks)


  • Enterprise-grade infrastructure: Harness the processing power of our globally distributed cloud-hosted node network. Our API alleviates the friction of maintaining your own compute and storage resources, lowering the barrier to entry for developers and enterprises.
  • Built for developers: Easy to read documentation and resources to help developers get started quickly.
  • Gain app insights: Our dashboard provides direct insights about API usage. Drill down into specific request methods and get response times, most used endpoints, usage by time of the day, IP address, countries and more. These insights are a great way to optimize applications based on user behaviour.
  • Standard Interface: Supports Mainnet and Testnet via client-compatible REST API over HTTPS.
  • Always Online: Running on the latest network upgrades with a minimum 99.9% uptime guarantee.

API Pagination

  1. Make a request with the desired size and check the result, if the cursor is not empty, construct a new request with the same parameters as the previous one. However, this time, take the cursor value from the last query and use it as the cursor parameter in the new request.
  2. If the cursor is empty in the result it means there are no more items to be retrieved.
