x402
three.ws Gas Oracle is a paid API for AI agents from three.ws, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-23).
Returns current gas price estimates across Base, Solana, and Ethereum networks, including tiered gas prices, base fees, and priority fees.

How this service works
Make a 3D AI agent from a selfie in 60 seconds. Drop one HTML tag to embed it on any website. Agents think on IBM watsonx.ai (Granite); optionally charge per chat with built-in micropayments.
Output
A JSON object with a timestamp and per-network gas data: for Base and Ethereum, tiered gas prices (standard key, gas_price_gwei, priority_fee_gwei) and base_fee_gwei; for Solana, base_fee_lamports and priority_fee_micro_lamports broken down by p25, p50, and p90 percentiles.
Example use cases
Optimize transaction timing on Ethereum
“What's the current standard gas price and priority fee on Ethereum? I want to know if it's a good time to submit my transaction or if I should wait for fees to drop.”
Estimate Solana transaction cost
“What are the current base fee in lamports and p90 priority fee in micro-lamports on Solana right now so I can budget my transaction cost?”
Compare fees across chains before bridging
“I need to bridge some funds and want to compare current gas fees — can you pull the current base fee and standard gas tier for Base, Ethereum, and Solana all at once?”
Technical details
Endpoint
GEThttps://three.ws/api/x402/gas-oracle?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, multi-chain gas price data covering Base, Ethereum, and Solana in a single call. Prefer it over chain-specific RPC gas estimation when you want cross-chain comparison, tiered estimates (standard priority), and Solana percentile breakdowns without writing custom RPC logic. The $0.001 USDC per-call cost is negligible for agents that need reliable, normalized gas data.
Side effects
- Network or upstream oracle unavailability returns an error or stale timestamp
- Payment of $0.001 USDC not provided or rejected via x402 protocol results in 402 Payment Required
- Malformed response if underlying gas oracle data sources are temporarily unavailable
- Rate limiting if too many requests are made in a short window
