How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
Returns the raw upstream DexScreener API response, including token pair metadata, current price, liquidity depth, trading volume, price change percentages, and transaction counts, passed through after successful x402 micropayment authorization.
Example use cases
New token launch price check
“Look up the current price and liquidity for this newly launched Solana token at address 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU on DexScreener.”
DEX arbitrage opportunity scan
“Fetch DexScreener data for the WBTC/USDC pair across all DEXes so I can compare prices and spot any arbitrage opportunities.”
DeFi portfolio token monitoring
“Get the 24-hour trading volume and price change for my token holdings — start with PEPE on Ethereum from DexScreener.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/dexscreener?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need DexScreener DEX and token data and want to pay per-call via x402 micropayments without managing a DexScreener API key. Ideal for AI agents operating in web3 environments with on-chain payment rails, or when building DeFi tools that need real-time token pricing and liquidity data on a usage-based cost model.
Side effects
- Payment failure: insufficient USDC balance or x402 handshake rejected — returns 402 Payment Required
- Invalid path: malformed or unsupported DexScreener sub-path — upstream returns 404
- Rate limiting: DexScreener upstream throttles repeated requests — returns 429
- Invalid token address: queried token does not exist on DexScreener — empty or error response passed through
- Network timeout: upstream DexScreener API unavailable — returns 502 or 504
