The Blockchain API

·

The Blockchain API empowers developers to seamlessly interact with decentralized networks using a unified, intuitive interface. Whether you're building on Solana, Ethereum, or other major blockchains, this API simplifies complex blockchain operations—from wallet management and NFT creation to transaction tracking and real-time monitoring. Designed for speed, scalability, and ease of use, it supports multiple programming languages and offers robust documentation to accelerate development.

With built-in support for wallets, tokens, NFTs, candy machines, and transaction metadata, the API removes the friction of working directly with blockchain nodes. Developers gain instant access to powerful tools without managing infrastructure, making it ideal for dApps, marketplaces, analytics platforms, and more.

Getting Started with the Blockchain API

To begin using the Blockchain API, generate your API key pair via the dashboard. This process takes under a minute: sign up, log in, and create your credentials. Once generated, you can immediately start making authenticated requests across all supported endpoints.

Each user receives 50,000 free credits per month, allowing extensive testing and development at no cost. Credits are consumed based on endpoint usage—some are free (e.g., deriving keys), while others require minimal deductions (e.g., minting NFTs). You can monitor your usage and upgrade plans as needed through the billing portal.

For custom enterprise needs or volume discounts, contact the team directly. The API welcomes feedback and feature requests to continuously improve functionality and developer experience.

Core Features Overview

Security Best Practices When Using Seed Phrases

The Blockchain API requires seed phrase input for certain wallet operations—this is essential for signing transactions securely. However, never expose your primary wallet’s seed phrase. For safety:

For example, when minting an NFT on Solana, create a new wallet via the Generate Secret Recovery Phrase endpoint. Transfer a small amount of SOL (less than $0.01) to cover gas, perform the action, then discard or archive the wallet.

The API provides secure endpoints to:

Constructive feedback is welcome—reach out to discuss concerns or suggest improvements.

Frequently Asked Questions

Q: Is it safe to provide my seed phrase to the API?
A: Only use non-primary wallets with the API. Your seed phrase is transmitted securely over HTTPS and never stored. However, always follow the principle of least privilege—use temporary wallets for API interactions.

Q: Can I use private keys instead of seed phrases?
A: Yes. Most endpoints accept either a secret recovery phrase, a private key (in hex or base58), or a B58-encoded private key. Using pre-derived keys adds an extra layer of control.

Q: What happens if I lose my API key?
A: You can regenerate your keys at any time from the dashboard. Old keys are automatically invalidated upon regeneration.

Q: Are there rate limits?
A: Free-tier users enjoy generous limits within their monthly credit allowance. Enterprise users can request higher thresholds based on usage patterns.

Q: Does the API support mainnet and testnet environments?
A: Yes. Most endpoints allow you to specify devnet or mainnet-beta (Solana) or ropsten/mainnet (Ethereum), enabling safe testing before production deployment.

Working with Solana Wallets

Generate a New Wallet

Creating a wallet starts with generating a secret recovery phrase (also known as a mnemonic). This phrase is the root of your wallet's cryptographic identity.

Use the /wallet/generate-secret-recovery-phrase endpoint with your chosen blockchain (e.g., solana) to get a BIP39-compliant 12–24 word phrase.

{
  "secret_recovery_phrase": "fire owner display success half rescue pledge oval foam gossip window once"
}

From this phrase, you can derive multiple private and public key pairs using different derivation paths.

Derive Private and Public Keys

Once you have a seed phrase, use the /wallet/derive-private-key endpoint to obtain the corresponding private key:

{
  "hex_private_key": "0x200b9e5baa38b0dc7551645be11b394e9bf2b04532e4af8824bed2b3de2e0dc0"
}

Then, derive the public key using /wallet/derive-wallet-identifier:

{
  "hex_public_address": "0xB2b2d42C3adA171633E36b427F062f85A642F453",
  "hex_public_key": "0x0f7182c2c2f79aca13847bed68c67662c021df86..."
}

These identifiers allow you to receive funds and verify ownership.

Managing NFTs on Solana

Create an NFT

Use the /solana/nft/mint endpoint to create a Metaplex-compatible NFT. You’ll need:

Choose between:

Cost: 5 Credits

Example request body:

{
  "name": "Super Musk",
  "symbol": "MUSK",
  "image_url": "https://example.com/image.jpg",
  "upload_method": "S3",
  "network": "devnet"
}

Response includes mint address and confirmation status.

Transfer an NFT or Token

Send SOL, SPL tokens, or NFTs using /solana/wallet/transfer. Specify:

Cost: 2 Credits

Example:

{
  "wallet": { "secret_recovery_phrase": "..." },
  "recipient_address": "EW3nXn7X4NTWFKWaJgxKrFNoTSkop1cBUVHA21zrfF6u",
  "token_address": "CK1LHEANTu7RFqN3XMzo2AnZhyus2W1vue1njrxLEM1d"
}

Returns transaction signature and confirmation status.

Cross-Chain Support

The API supports multiple blockchains beyond Solana:

Common functions like balance checks, transfers, and airdrops work consistently across chains via standardized endpoints.

Example: Get wallet balance in native currency or token:

POST /wallet/get-balance
{
  "blockchain_identifier": "0xa84b...f6aAA",
  "token_blockchain_identifier": "0xa0b8...eb48" // USDC
}

Response:

{
  "balance": 1500.5,
  "decimals": 6,
  "network": "mainnet"
}
