Do I Need These?
QuantaPay works out of the box without any API keys by using public blockchain explorers. However, adding API keys provides:
- Higher rate limits — Public endpoints may throttle requests during peak times
- Better reliability — Dedicated API keys ensure consistent uptime
- Faster verification — Priority access to blockchain data
Recommended Setup
For most merchants, we recommend at minimum:
- Etherscan — If you accept ETH or ERC-20 tokens (USDT, USDC, LINK, etc.)
- BscScan — If you accept BNB or BEP-20 tokens (USDT BSC, BUSD)
All API keys are free to obtain from their respective provider websites.
