How this service works
ARYSPHERE sells AI-written verdicts on Base token contracts (a grade, a one-liner, a roast and the contract's facts) and Base/Ethereum chain reads, paid per call in USDC on Base over x402 v2. No account and no API key.
Output
Returns the current Ethereum mainnet gas price expressed in wei as a single numeric value, reflecting live network conditions at the time of the request.
Example use cases
Pre-transaction gas cost check
“Before I send this ETH transfer, can you check the current Ethereum mainnet gas price so I know what fees to expect?”
Gas price spike monitoring
“Is the Ethereum gas price unusually high right now? Grab the current wei value and let me know if I should wait before submitting my transaction.”
DeFi bot gas optimization
“Pull the current Ethereum mainnet gas price in wei — I need to decide whether to execute this DeFi swap now or hold off until fees drop.”
Technical details
Endpoint
GEThttps://api.arysphere.com/v1/ventures/x402_eth_reads_v1/eth_mainnet_gasprice?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, no-parameter lookup of the current Ethereum mainnet gas price in wei, especially in agentic workflows where x402 micropayment billing per call is acceptable and you do not need a full gas estimation service with input transaction data.
Side effects
- Network or RPC node outage causing unavailability of gas price data
- Rate limiting if the endpoint is called too frequently
- Stale data if the underlying node is behind the chain tip
- Payment failure if the $0.003 USDC x402 payment is not properly attached
