Does Omni Wallet have an API?

Does Omni Wallet have an API?

Yes, Omni Wallet does have an API that provides access to various functionalities such as integration with Armory wallet, support for OmniBOLT and OmniWallet, and more. However, an alternative to using Omni Wallet's public API is the Mesh API, which has built integrations with Omni Wallet along with 300+ other digital asset exchanges and wallets.

About Omni Wallet

Omni Wallet, founded in 2021, is a multi-chain staking wallet that simplifies the process of staking cryptocurrency. Headquartered in New York, the company offers services such as transmitting, receiving, staking, and delegation of cryptocurrency assets between blockchains. With a small team of 1-10 employees, Omni Wallet has managed to secure $11 million in Series A funding, showcasing its potential in the crypto space.

General usage

Here's a brief summary of Omni Wallet’s APIs:

  1. Armory Wallet Integration APIs: These APIs facilitate the integration with Armory wallet, providing functionalities like converting raw bitcoin transactions to Armory encoded format and decoding Armory transactions.
  2. OmniBOLT and OmniWallet APIs: These APIs are documented and provide support for OmniBOLT (a lightning network solution for Omni Layer assets) and OmniWallet. Detailed documentation is available on GitHub, but specific functionalities are not explicitly listed in the available resources.
  3. OmniJ APIs: These APIs are designed for Java and provide support for Omni Protocol. They include functionalities for Omni Core RPC client, Omniwallet REST client, consensus data comparison, and transaction creation for the Omni Protocol. Specific packages within OmniJ offer various functionalities, such as support for Omni MainNet, TestNet, and RegTest networks, JavaMoney support for OMNI and OmniLayer tokens, and classes for creating Omni Protocol transactions.

Rate Limits

Omni Wallet’s API rate limit is:

  • Users are advised to wait a minimum of 5-10 seconds between repeat calls to prevent triggering the API rate limiter.


This is how you authenticate your Omni Wallet API:

  1. Generate an API key via the Omni Wallet website, and note down the key, secret, and passphrase (if applicable).
  2. Select the appropriate permissions for your API key based on your needs.
  3. Include the required headers (e.g., API key, signature, timestamp, and passphrase) in your API requests.
  4. Calculate the timestamp header as the number of seconds since Unix Epoch in UTC (if required).
  5. Create the signature header by generating a hash (e.g., HMAC) using the secret key on the prehash string, which includes the timestamp, method, request path, and body (if applicable). Encode the resulting signature and include it in the signature header (if required).


Here are the most common API errors for Omni Wallet API:

  • Rate limit exceeded: If you encounter issues related to rate limits, ensure you're following proper coding techniques and maintaining a minimum wait time of 5-10 seconds between repeat calls.
  • Authentication issues: In case of authentication problems, double-check your API key, secret, passphrase, and required headers in your API requests.
