How this service works
One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.
Output
Returns the best expected output token amount for the exact-input swap, along with the winning fee tier and pool details, sourced from Uniswap V3 on the specified chain. This is a spot quote only — not a firm or executable price.
Example use cases
Pre-trade price check for DeFi bot
“Before my trading bot executes, get me the best Uniswap V3 quote on Ethereum for swapping 5000 USDC (0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48) into WETH (0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2) — I need the expected output and which fee tier wins.”
Arbitrage opportunity scan on Base
“Check the Uniswap V3 quote on Base for swapping 10000 USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) into cbETH (0x2Ae3F1Ec7F1F5012CFEab0185bfc7aa3cf0DEc22) using the exact decimal amount 10000 — I want to know the best output across all fee tiers.”
Portfolio rebalancing price estimate
“I want to rebalance my portfolio on Ethereum — give me a Uniswap V3 spot quote for swapping 2.5 WETH (0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2) into DAI (0x6B175474E89094C44Da98b954EedeAC495271d0F) so I can decide if now is a good time.”
Technical details
Endpoint
POSThttps://tanod.dev/v1/chain/quote?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, read-only Uniswap V3 swap quote on Ethereum or Base and want automatic fee-tier selection (0.01/0.05/0.3/1%) to find the best rate. It is ideal for pre-trade price checks, DeFi arbitrage scanning, portfolio rebalancing estimates, or any agent workflow that needs a spot price without executing a transaction. Prefer this over on-chain calls when you want a simple REST interface without managing Web3 infrastructure.
Side effects
- No liquidity pool exists for the token pair and fee tier combination — returns an error or empty result
- Invalid token address format (must be 0x + 40 hex chars) — returns validation error
- Both amount_in and amount_in_raw provided, or neither — returns parameter conflict error
- Unsupported chain value — returns validation error (only 'ethereum' and 'base' accepted)
- Network or RPC connectivity issues to the specified chain — returns service error
- Token pair has insufficient liquidity across all fee tiers — may return zero or degraded quote
