How this service works
Pay-per-call live data APIs settled in USDC on Base (Ethereum) mainnet via x402. No accounts, no API keys — just a wallet. Covers live crypto ticker prices, GitHub repo metrics, Base gas price, and token market data. Payment goes to the operator's Base address.
Output
A JSON object with a 'gas' field containing three numeric sub-fields — standard, fast, and instant — representing gas price tiers in Gwei, plus a 'source' field indicating the data provider (Blocknative).
Example use cases
Pre-transaction gas check
“Before I send this USDC transfer on Base, check the current gas price so I can pick the cheapest tier that still confirms quickly.”
Gas spike monitoring for DeFi bot
“Fetch the live Base gas price right now — I want to know if standard is under 2 Gwei before my bot executes the next swap.”
Dashboard gas price widget
“Pull the latest Base gas price tiers so I can display standard, fast, and instant Gwei values on my on-chain analytics dashboard.”

Endpoint
GEThttps://x402-20260909-agent.projectk.org/gasWhen to prefer
Choose this endpoint when you need real-time Base network gas prices without API key registration, and you're already operating in an x402 micropayment context with a funded Base wallet. Ideal for agents that need pay-as-you-go gas data without subscription overhead. Prefer over free alternatives when you need a reliable, operator-maintained feed with Blocknative as the source.
Side effects
- Payment failure: wallet lacks sufficient USDC on Base mainnet — endpoint returns HTTP 402
- Blocknative data unavailable: upstream provider outage may cause stale or missing gas data
- Network congestion: response latency may increase during high Base network activity
- Invalid wallet/payment credentials: x402 payment handshake fails, returning auth error
