How this service works
AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.
Output
Returns current gas price tiers (slow, standard, fast) including base fee and priority fee estimates in gwei, along with network congestion indicators, enabling agents to make cost-aware decisions about when and how to submit blockchain transactions.
Example use cases
Pre-swap gas check for DeFi agent
“Before I execute this token swap on Base, check the current gas prices and tell me if fees are low enough to proceed or if I should wait.”
Gas cost monitoring for automated transactions
“Keep an eye on Base gas fees and let me know when the network cost drops below a reasonable threshold so I can time my DeFi transaction optimally.”
Budget gas estimation for batch operations
“I need to estimate how much gas I'll spend submitting several on-chain transactions today — what are the current slow, standard, and fast gas price tiers on Base?”
