A second opinion at the buy button.

No key, CORS open, cached for a minute. If the network has not checked the token yet, status is not_checked — ask for a check below.

The cores answer in about a minute. Poll the GET endpoint until status is checked. Fresh checks share the site's daily limits — call it when a token is new or its last check is old (see age_hours), not on every page view.

curl -X POST https://www.coreum.xyz/api/v1/check \
  -H "content-type: application/json" \
  -d '{"address": "0x3a2ec7aeb4b3c3d6ae9ff6f390bc9da05a8cb945"}'

→ 202 {"job": 99, "status": "checking", "page": "https://www.coreum.xyz/v/99", ...}

50 checks a day per IP for free. For more, burn 1,000,000 $CORS on /cors for an API key with 500 checks a day for 30 days, and send it as a header:

curl -X POST https://www.coreum.xyz/api/v1/check \
  -H "authorization: Bearer cak_…" \
  -H "content-type: application/json" \
  -d '{"address": "0x3a2ec7aeb4b3c3d6ae9ff6f390bc9da05a8cb945"}'

Trading agents can ask the network before they buy. Coreum runs a remote MCP server: add it to Claude, Cursor or any MCP client and call check_token with an address. The agent gets the grade, every deduction, a signal (ok / caution / avoid) and the proof link.

$CORS (COREUM) on Robinhood Chain
Grade: B (80/100) · signal: ok
Verdict: MIXED · 40% of 5 cores agree
Deductions:
  -20 Cores were split or unsure
Proof (sealed on Robinhood Chain): https://www.coreum.xyz/v/107

The latest grade of every checked token is written every hour into CoreumTokenRegistry on Robinhood Chain. A launchpad, a swap or a vault can read it in one call, with no API and no trust in our servers.

interface ICoreumTokenRegistry {
  // true when the token was graded A or B within maxAge seconds
  function isClean(address token, uint256 maxAge) external view returns (bool ok, uint8 letter);
}

ICoreumTokenRegistry constant COREUM = ICoreumTokenRegistry(0x32F69057dFda5785A898e33933853aBD0EEF1Db7);

(bool ok, ) = COREUM.isClean(token, 1 days);
require(ok, "Coreum: no recent clean grade");

gradeOf(token) returns the full entry: letter (1 A to 5 F), score, verdict, agreement, job id and check time. The list it is written from: https://www.coreum.xyz/api/v1/grades

• NO_RED_FLAGS — the cores found no major rug-pull signs in the facts shown.
• RED_FLAGS — clear risks: honeypot, an owner or deployer able to control supply, near-zero liquidity, a few wallets holding most supply after graduation, a deployer whose earlier launches mostly died.
• MIXED — the cores disagree or the data is too thin.

It is a risk screen from public on-chain facts, not an audit and not financial advice. Facts come from GeckoTerminal and the chain; anyone can recompute every hash with the open verifier.

Free while in beta. Reads are cached and unmetered; fresh checks follow the site's daily limits per IP. Need more checks for a launchpad or a wallet? Message @0xcoreum. The code is open source.
