How this service works
OpenAI-compatible AI and data API for agents. Pay per call in USDC on Base via x402 — no API keys, no subscriptions, no lock-in.
Output
A JSON object containing current gas price estimates for the Base network, broken down by speed tier: 'fast' (e.g. 0.002) and 'standard' (e.g. 0.001), returned as string-formatted numeric values.
Example use cases
Pre-transaction fee check
“Before I submit this transaction on Base, can you check what the current fast and standard gas prices are so I know how much it'll cost?”
DeFi bot cost optimization
“I'm running an automated trading bot on Base — can you grab the latest standard gas price so I can decide whether it's cheap enough to execute right now?”
Gas price monitoring alert
“Check the current gas prices on Base and let me know if the fast gas price has dropped below 0.003 gwei yet.”
Technical details
Endpoint
GEThttps://api.cortexcloud.org/x402/v1/data/gasWhen to prefer
Choose this endpoint when you need real-time Base network gas prices in a pay-per-call model without API key setup. Ideal for agents that need occasional gas price lookups without committing to a subscription, or for autonomous agents that pay via x402 USDC micropayments on Base.
Side effects
- Payment not included or insufficient USDC — returns HTTP 402 requiring x402 micropayment
- Base network RPC unavailable — may return stale or error response
- Invalid properties filter parameter — may return 400 bad request
- Network timeout if Base RPC is congested
