How this service works
BUNDLE: one-call Base market snapshot combining live gas (base fee, priority-fee percentiles, congestion) AND WETH/USDC spot price + gross spread across Uniswap v3 / Aerodrome. Use this when you want both gas and DEX pricing in a single cheaper call; do NOT also call gas-optimizer or dex-arbitrage for the same purpose. Prefer the individual tools only if you need just one of the two.
Output
Returns a unified JSON object containing: live Base network gas data (current base fee, priority fee percentiles at multiple levels, congestion indicator) and WETH/USDC DEX pricing data (spot price from Uniswap v3 and Aerodrome v2, gross spread between venues). All data is read on-chain in real time.
Example use cases
Pre-trade gas and price check
“Before I submit this WETH/USDC swap on Base, can you pull the current gas fees and live WETH price together so I can decide if it's worth executing right now?”
DeFi dashboard market feed
“I'm building a dashboard — grab me the latest Base network snapshot with gas base fee, priority fee percentiles, congestion status, and the WETH/USDC spot price from both Uniswap v3 and Aerodrome in one call.”
Arbitrage opportunity monitor
“Check the current WETH/USDC spread and gas costs on Base right now — I want to know if the gross spread across Uniswap and Aerodrome is wide enough to cover gas and still be profitable.”
Technical details
Endpoint
POSThttps://auditor-x402.onrender.com/api/base-market-snapshot?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need BOTH gas metrics and WETH/USDC DEX pricing for Base in a single request — it is cheaper and faster than calling the gas-optimizer and dex-arbitrage endpoints separately. Prefer the individual sibling endpoints only when you need exclusively gas data or exclusively DEX pricing, not both.
Side effects
- RPC node unavailability causing on-chain read failure
- Uniswap v3 or Aerodrome pool data temporarily inaccessible
- Payment not fulfilled resulting in 402 rejection
- Malformed POST body returning 400 validation error
- Render.com cold start latency causing timeout on first request
