How this service works
Base-native onchain data for AI agents — gas, token prices by contract, address analytics, DEX pools, new-token radar. From $0.001 a call in USDC via x402. No API keys. Open source.
Output
A JSON object containing the timestamp of the price snapshot, the USD price as a float, the chain identifier ('base'), the token contract address queried, and the data source (e.g. 'geckoterminal').
Example use cases
DeFi portfolio USD valuation
“What's the current USD price of the token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base? I need to calculate the USD value of my holdings.”
Arbitrage price monitoring
“Fetch the latest USD price for the Base token at contract 0x4200000000000000000000000000000000000006 so I can compare it against another exchange.”
Token price alert trigger
“Check the current price in USD for the Base token at 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb and tell me if it's above $0.10.”
Technical details
Endpoint
GEThttps://agenttoll.app/api/base/token/%7Baddress%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, lightweight USD price for a specific ERC-20 token on Base by its contract address, especially in agent workflows that require no API key setup and support x402 micropayments. Prefer this over broader market data APIs when you specifically need Base-native onchain pricing sourced from DEX pools rather than centralized exchange data.
Side effects
- Token contract address not found on Base — returns error or null price
- Invalid or malformed contract address — returns 400-level error
- Token has no liquidity or DEX pool — price unavailable
- GeckoTerminal upstream unavailable — stale or missing data
- Payment not fulfilled via x402 — request blocked with 402 response
