Does f(x) Wallet have an API?

Yes, f(x) Wallet does have an API, which provides access to various features such as Asset Management, Blockchain Interaction, DApp Exploration, Security and Key Management, User Experience, and Transaction Management. However, an alternative to using f(x) Wallet's public API is the Mesh API, which has built integrations with 300+ digital asset exchanges and wallets, allowing developers to build products that enable users to access their digital assets from various platforms, all via a single integration with Mesh.

About f(x) Wallet

f(x) Wallet is a decentralized, non-custodial wallet that supports ERC-20 and Function X tokens, with upcoming support for Binance Smart Chain and Bitcoin blockchain.

Additionally, f(x) Wallet provides fiat on-ramp support for users in over 170 countries, making it a versatile choice for managing digital assets.

General usage

  5. User Experience APIs: These would include APIs to enhance the user experience, such as language settings, layout customization, and managing visibility of tokens and blockchains within the wallet interface.
  6. Transaction Management APIs: Given the wallet's functionality, APIs in this category would handle sending digital assets, managing transaction fees, and ensuring transactions are processed on the blockchain.

Authentication

  3. Include the necessary headers in your API requests, such as the API key, signature, timestamp, and passphrase.
  4. Calculate the timestamp header as the number of seconds since Unix Epoch in UTC.
  5. Create the signature header by generating a hash 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.
