How this service works
Current gas price on Polygon PoS (eth_gasPrice): gas price, base fee and suggested priority fee in gwei, plus what a plain POL transfer (21,000 gas) costs right now. Takes no input. Use before sending a transaction or to decide whether to wait; for the fee a past transaction actually paid use polygon_receipt.
Output
A JSON object containing the current Polygon block number, chain name, native symbol (POL), chain ID (137), base fee in Gwei, overall gas price in Gwei, priority fee in Gwei, and estimated cost in POL for a standard ETH transfer.
Example use cases
Pre-transaction gas estimation
“Before I send this token transfer on Polygon, can you check what the current gas price is and estimate how much it'll cost me in POL?”
Cheapest chain selection
“I need to make a transaction and I'm deciding between chains — what's the current gas price on Polygon right now in Gwei?”
Gas spike monitoring alert
“Keep an eye on Polygon's gas price for me — is the base fee currently above 0.1 Gwei, or is it low enough to transact cheaply right now?”
Technical details
Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/polygon/gas?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time Polygon PoS gas fee data (base fee, gas price, priority fee, transfer cost) without setting up an account or API key — paying only $0.001 USDC per call via x402. Prefer this over self-hosted RPC calls when operating in a serverless or agent context that needs pay-per-use pricing with zero setup.
Side effects
- RPC node unavailability causing upstream timeout
- Polygon network congestion causing stale or delayed data
- Invalid or unexpected chain state returning null fee fields
- x402 payment failure resulting in no charge and no response
