How this service works
Pay-per-call x402 APIs for AI agents: OpenAI-compatible LLM chat, perp funding and arbitrage spreads, crypto prices, gas, FX, Solana SPL mint audit, token price by contract, x402 delivery-receipt verification, web search, clean page extraction, batch tools and deterministic code-security scanning. USDC on Base or Solana, no signup, no API key, from $0.0001 a call.
Output
A JSON object containing the network name (e.g. 'base' or 'ethereum'), the current base_fee_gwei, gas_price_gwei, and an estimates object with slow, normal, and fast tiers each showing their max_fee_gwei value.
Example use cases
Pre-transaction gas check on Base
“Before I submit this Base transaction, can you check what the current slow, normal, and fast gas fees are so I can pick the right one?”
Gas monitoring for cost-sensitive DeFi bot
“My DeFi bot only executes trades when gas on Ethereum is below 0.05 gwei — can you fetch the current base fee and estimates so I can decide whether to proceed?”
Gas price comparison across networks
“Can you pull the live gas estimates for both Base and Ethereum so I can compare which network is cheaper to transact on right now?”
Technical details
Endpoint
GEThttps://scanpay-edge.alextaghiashvili.workers.dev/api/v1/gas-estimate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, tiered gas fee estimates (slow/normal/fast) specifically for Base or Ethereum, especially in agent workflows that need to decide whether to submit a transaction or compare network costs. It is well-suited for pre-transaction checks, cost-sensitive automation, or any agent that needs live gwei values without running its own RPC node.
Side effects
- Upstream RPC node unavailable — may return 5xx or stale data
- Invalid or unsupported network specified — likely returns 400 or error message
- Payment not fulfilled (x402 protocol) — returns 402 Payment Required
- Rate limiting or Cloudflare Worker quota exceeded — returns 429 or 503
