Dex trading agent signal API and crypto market signal feed for agents. Returns the latest Dex trading agent read for supported crypto symbols, including action, confidence, risk, drivers, leverage context, and monitoring notes.

Returns a DeFiLlama-style overview of DEX activity and market metrics.

DEX swap quote and best route ($0.005): how much you get now across Uniswap v2/v3/v4 and Aerodrome (direct or through WETH) on Base, Ethereum, Arbitrum, Optimism or Polygon, with price impact, the minimum to accept at your slippage and alternative routes. Simulated with eth_call; nothing is executed. Use right before an on-chain swap.

Use when an agent must put a number on a token before trading or reporting, and be able to defend it: spot price read straight from the deepest Uniswap V3 pool against USDC, on Base, Ethereum, Polygon, Arbitrum or Optimism. Returns the pool address, fee tier, liquidity, sqrtPriceX96, tick and block, so the number can be audited instead of trusted. No aggregator and no API key: the source is the chain itself. Via eth_call.

Decentralized exchanges ranked by 24h spot volume with 7d, 30d, 1y and all-time volume, change, the chains each trades on and sector totals. Use it when an agent needs to know where onchain spot volume is happening or how a DEX's share is moving.

DEX vs CEX arbitrage spread — the price difference between DEX and CEX with the fee-adjusted NET spread and execution direction, not two raw prices. Compares the most liquid DEX pair (DexScreener) to CEX spot (Binance/Bybit), subtracts taker+swap fees, and flags any profitable arbitrage opportunity. For arbitrage agents.

Recent DEX swap history + buy/sell flow for a token or pool on Base: per-swap trader/side/amount/price plus a summary (count, buy/sell volume, net flow, largest swaps), decoded by us from public Aerodrome/Uniswap-V3 Swap event logs.

Trending Base DEX pools ranked by recent swap volume and net buy/sell flow over a short window, computed by us from public Aerodrome/Uniswap-V3 Swap event logs.

Read a token's DEX pair straight from the chain: pair address, both reserves, the implied price, LP total supply and how much of that LP sits in burn addresses. Base, Arbitrum and BNB Chain, Uniswap V2-style factories against the wrapped native token. Read-only eth_call, no API key. The answer states its own limits: no pair here does not mean no liquidity, because V3, other DEXes and non-native quote pairs are not covered.

A deliberately cheap paid call, for checking that your wallet, network and x402 client actually work against this gateway before you spend more on a real product. It settles a real payment and echoes back what we saw: network, scheme, amount and your address.

Read any wallet balance on 28 EVM chains: native coin (ETH, BNB, MATIC, AVAX) or any ERC-20 token including USDC. Covers Base, Ethereum, Arbitrum, Optimism, Polygon, BSC, Avalanche, zkSync, Linea, Scroll, Blast, Mantle, Celo, Gnosis, Sonic, Unichain, World Chain, Zora and more. Returns the raw and decimal balance with the block it was read at.

Make any read-only JSON-RPC call on 28 EVM chains - eth_call, eth_blockNumber, eth_getLogs, eth_getBalance and the rest - without running a node or holding an RPC key. Covers Base, Ethereum, Arbitrum, Optimism, Polygon, BSC and more, with automatic failover across providers when one rate-limits or goes down.

Look up any transaction and its receipt by hash on 28 EVM chains: success or revert, block number, gas used, effective gas price, sender and recipient. Covers Base, Ethereum, Arbitrum, Optimism, Polygon, BSC and more. Use it to confirm a payment or settlement actually landed.

Lightweight swap quote for Base without calldata: give tokenIn, tokenOut and raw amountIn and get the max-output route across Aerodrome and Uniswap V3, the buy amount, amountOutMin, price impact and the venues compared. A cheap price check before you build the full transaction.

Non-custodial swap calldata for Base: give tokenIn, tokenOut, raw amountIn, slippage and recipient; we read Aerodrome and Uniswap V3 on-chain state, pick the max-output route, and return ready-to-sign transaction calldata plus the ERC-20 approval, amountOutMin, price impact and the venues compared. You sign with your own wallet — we never hold or move funds.
