1. Unified Blockchain Access​

Single API interface works across all supported chains:

# Ethereum balance
curl https://api.axol.io/api/v1/blockchain/ethereum/balance/0x123...

# Solana balance
curl https://api.axol.io/api/v1/blockchain/solana/balance/abc123...

# Same pattern, different chains

# Current gas prices
GET /api/v1/gas/ethereum

# Response
{
  "slow": 20,
  "standard": 25,
  "fast": 30,
  "instant": 35,
  "timestamp": "2025-10-12T10:30:00Z"
}

Gas API Features:

  • Real-time prices for 7+ EVM chains
