It returns aggregated DEX trading volume data, including total 24-hour volume and per-protocol breakdowns (e.g., Uniswap). The endpoint requires no query parameters — a simple GET request returns the current volume snapshot. Payment is handled via the x402 protocol at $0.01 USDC per call on Base.\n\nThis endpoint is one of 26 DeFi-focused endpoints offered by the same API, which covers token security audits, rugpull detection, bridge routing, gas prices, TVL, protocol fees, and more. All endpoints follow the same x402 pay-per-call model with no API keys or rate limits required. Alternative access methods include a broker API (with an API key and prepaid credit), an MCP server at mcp.hugen.tokyo, and a Python SDK (`x402-pay`).\n\nThe response schema for this specific endpoint is not formally documented beyond the sample in the 402 challenge, which shows fields like `totalVolume24h` (a numeric value in USD) and a `protocols` array with `name` and `volume24h` per protocol. The endpoint was confirmed live via a 402 challenge response during probing.","tags":[],"capabilities":["dex-volume","defi-analytics","protocol-volume-breakdown","x402-micropayment","no-api-key","pay-per-call"],"categories":["defi","data"],"synonyms":["DEX trading volume","decentralized exchange volume","Uniswap volume","DeFi volume API","DEX 24h volume","protocol volume data","crypto exchange volume"],"warnings":["Response schema is not formally defined in the OpenAPI spec — the sample in the 402 challenge is the only documentation of the response shape.","No dedicated docs page for this endpoint beyond the auto-generated Swagger listing.","The sample response in the 402 challenge may not represent the full response structure.","Similar DEX volume data is available for free from DefiLlama and other aggregators."],"endpointUrl":"https://defi.hugen.tokyo/defi/dex/volume","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x29322Ea7EcB34aA6164cb2ddeB9CE650902E4f60","amount":"5000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300},{"asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","extra":{"feePayer":"BENrLoUbndxoNMUS5JXApGMtNykLjFXXixMtpDwDR9SP"},"payTo":"4du4AfkjJEwch2zk3shkPJVZfyJHNDnNjEWC6AboaS5Z","amount":"5000","scheme":"exact","network":"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp","maxTimeoutSeconds":300}]},"qualityScore":"0.550","qualityRationale":"The endpoint is confirmed live via a 402 challenge, and the OpenAPI spec documents the route.
