Check any token's risk on Base with one HTTP call (free demo)

CallBrief — Tue, 20 Oct 2026 03:23:55 GMT

Before you touch a token, you want the same facts a scanner gives you: liquidity, holder concentration and contract red flags. token-risk returns all of it in one call, and the demo endpoint lets you try it free.

How it works

The paid call is x402 ($0.02 per call in USDC on Base): the first request returns HTTP 402 with a payment quote, your wallet client (or any x402-enabled fetch) pays from the quote, and the follow-up returns the report.

For a free look, use the demo endpoint: 5 calls per day per IP, no payment.

Try it

curl -i https://token-risk.restockalarm.workers.dev/demo/v1/risk?address=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913

A malformed address gets a clean error: HTTP 400 with "invalid address: expected 0x followed by 40 hex characters (an ERC-20 contract on Base)".

How to read it

Score 0-100, higher is riskier. 23 with $42.3M pooled liquidity and no honeypot is what a safe major coin looks like. A meme token with locked liquidity in one wallet and a pause function looks very different, and this is the report that shows it.
