Token claims, with the evidence attached.
Give your bot or community a brief that separates supported claims from open questions. Every assessment includes its sources. Each Base token brief costs 0.25 USDC.

One JSON brief: decimals and total supply at a recorded block, up to three claim assessments, source citations and explicit unknowns. Use it in a bot response or community post.
The free Base USDC sample below uses the same brief structure as a purchase. Its timestamp shows when it was generated; it is not a live feed. A purchase generates a snapshot for your request.
What token or claim do you want checked?
Give your bot or community a sourced answer. Buy a Base token brief below for 0.25 USDC, or tell us what evidence you need next.
Need another token source, chain or kind of evidence?
Share the contract, chain and question you want answered. We’ll review the request and reply about coverage and pricing before you pay. Sending a request does not buy a brief or guarantee new coverage.

Check a Base ERC-20 contract and up to three claims. The browser form checks one claim. The API supports three.
Onchain coverage: decimals and total supply at a recorded block. Official project-source coverage currently includes Base USDC only. Other claims may remain unknown. This brief does not assess safety, reserves, liquidity or holders.
Use MetaMask with USDC on Base. Review the wallet signature before approving. No direct transfer or subscription is required.
