I Built a Solana Token Risk API — Scan Any Token in 2 Seconds

#api #solana #webdev #security

If you build anything on Solana that touches tokens — a trading bot, a portfolio tracker, a DEX aggregator — you need a way to check if a token is safe before your users interact with it.

I built an API that scores any Solana token from 0-100 based on on-chain signals. One endpoint, JSON response, under 2 seconds.

What It Checks

Mint authority: Can the creator mint unlimited tokens? (-30 points)
Freeze authority: Can wallets be frozen? (-20 points)
Top holder concentration: Does one wallet hold 50%+? (-30 points)
Holder count: Fewer than 10 holders? (-10 points)
Jupiter verification: Listed and verified? (+0 to -15 points)

The API

GET https://devtools-site-delta.vercel.app/api/scan?mint=TOKEN_ADDRESS&key=YOUR_API_KEY

Response:

{
  "score": 72,
  "verdict": "RELATIVELY_SAFE",
  "flags": {
    "mintAuthority": false,
    "freezeAuthority": false,
    "topHolderPct": 15.2,
    "holderCount": 847,
    "jupiterVerified": true
  }
}

Pricing

Free tier: 10 scans/minute (no key needed)
Pro: 0.08 SOL (~) for 1,000 scans/day
Unlimited: 0.4 SOL (~) for 100K scans/day

Pay once in SOL, get an API key instantly. No KYC, no credit card, no monthly billing.

Who Uses This

Trading bot developers who need to filter tokens before auto-buying
Portfolio trackers that want to warn users about risky holdings
DEX frontends that want to show safety scores next to token listings
Anyone building on Solana who wants to protect their users from rugs

Get Started

Free tier works without a key — just hit the endpoint. Pro and Unlimited keys are issued instantly after SOL payment is confirmed on-chain.

Built this as part of a larger Solana trading toolkit. The same scanner runs inside @solscanitbot on Telegram where it has processed thousands of scans.
