How this service works

Invoice-to-JSON, on-chain tools (transaction explainer + payment check, wallet profile, contract ABI, ERC-20 token risk), company contacts and web-to-RAG for AI agents. Pay per call with x402 (USDC on Base). No signup, no API key.

Output

A JSON object containing the token symbol, network, current USD price, liquidity in USD, market cap in USD, 24h trading volume in USD, and 24h price change percentage — all sourced from DEX pool data aggregated by GeckoTerminal.

Example use cases

DeFi portfolio price check

“Can you look up the current price and 24-hour change for the DEGEN token on Base — the contract is 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed?”

Solana token market cap lookup

“What's the market cap and liquidity for the Solana token with mint address So11111111111111111111111111111111111111112 right now?”

Arbitrum token due diligence

“Before I buy, can you pull the FDV, 24h volume, and current price for the token at 0x912CE59144191C1204E64559FE8253a0e49E6548 on Arbitrum?”

Technical details

Endpoint

GEThttps://freetier-agent-api.pages.dev/api/token-price?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need real-time DEX-sourced token prices for EVM chains (Base, Ethereum, Arbitrum, BSC, Polygon, Optimism, Avalanche) or Solana by contract/mint address. Ideal for DeFi agents that need on-chain market data rather than centralized exchange prices. Prefer over CoinGecko or CoinMarketCap endpoints when you have a contract address but no ticker symbol, or when the token is only listed on DEX pools.

Side effects

Unknown or unlisted contract address — token not found in GeckoTerminal DEX data
Missing required 'address' query parameter — returns validation error
Network mismatch — querying the wrong chain for a given contract returns no data
Very low-liquidity tokens may have unreliable or missing price/volume data
Solana mint addresses require network=solana explicitly or may default to base incorrectly
