How this service works
AI-powered real estate tools for property normalization, FHA compliance scanning, and investor metrics calculation. Powered by x402 micropayments.
Output
Returns a JSON object with the current Base network (eip155:8453) gas metrics: latest block number, base fee in gwei, gas price in wei and gwei, block gas utilization percentage, estimated USDC transfer cost in USD, a congestion level enum (e.g. LOW/MEDIUM/HIGH), an agent_recommendation string (e.g. EXECUTE_NOW), and a UTC timestamp.
Example use cases
Optimal transaction timing for agent
“Check Base network gas right now and tell me if I should execute my USDC micropayment immediately or hold off — what's the congestion level and your recommendation?”
Cost estimate before on-chain payment
“How much will it cost in gas to send a USDC transfer on Base right now? I want to know the estimated USD cost before I proceed.”
Real-time gas dashboard for DeFi bot
“Pull the latest Base network gas stats — base fee in gwei, current block utilization, and whether conditions are LOW, MEDIUM, or HIGH congestion — so I can decide when to batch my transactions.”
Technical details
Endpoint
POSThttps://sparks-re-api.sparksdigital-re.workers.dev/utilities/base-gas?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to make a real-time decision about whether to execute a Base-chain transaction — especially for x402 micropayment flows where gas cost affects ROI. Prefer this over generic gas APIs when you need a direct agent_recommendation signal and USDC-denominated cost estimates rather than raw gwei values alone.
Side effects
- Base RPC node unavailable — may return 503 or stale data
- x402 micropayment not fulfilled — returns 402 Payment Required
- Cloudflare Worker timeout if Base RPC is slow — may return 504
- Malformed request body returns 400 with schema validation error
