How this service works
Pay-per-call utility APIs in USDC on Base: Hebrew calendar and text tools, Shabbat times, Base token control-risk screen and address summary, plus finance arithmetic tools. General information and arithmetic only; not investment, tax or legal advice and not a recommendation to buy, sell or hold anything.
Output
Returns a JSON object with the token's chain (e.g. 'base'), symbol (e.g. 'USDC'), an array of control-risk flags (e.g. ['upgradeable proxy']), and a verdict string (e.g. 'many_control_signals') summarizing the overall risk level.
Example use cases
Pre-investment token safety check
“Before I buy any of this token, can you check the Base contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 for control-risk signals? I want to know the verdict and any flags like upgradeable proxy or admin controls.”
DeFi protocol due diligence
“I'm about to provide liquidity to a pool that uses this Base token at 0x4200000000000000000000000000000000000006 — can you run a control-risk screen on it and tell me what flags come up?”
Automated token screening in an agent workflow
“For every new Base token I'm considering adding to my watchlist, I need a quick risk verdict — can you screen 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb and tell me its symbol, chain, verdict, and any control flags?”
Technical details
Endpoint
GEThttps://heb-utils-x402.hebutils-api.workers.dev/base-token-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, structured risk-signal summary for a specific Base token contract address — particularly to surface control risks like upgradeability or admin key concentration before interacting with or listing a token. Prefer this over manual contract auditing when you need a programmatic, per-call verdict suitable for agent workflows or automated due diligence pipelines.
Side effects
- Invalid or non-contract address returns an error
- Non-Base chain addresses are not supported
- Unverified or newly deployed contracts may yield incomplete flag data
- Network or RPC timeout results in a service error
- Missing required 'address' query parameter returns a 400-level error
