Half the AML tools online say "free" and then ask for a credit card at the checkout. So we ran the question head-on: when you screen a crypto wallet for sanctions and risk, what does the free tier really cover — and at what point do you actually have to pay?
| Rank | Tool | Free tier | Paid | Sanctions covered | PDF report | Best for |
|---|---|---|---|---|---|---|
| 1 | @scorechain_amlbot / cryptoaml.ai | 3 checks/day | $0.50 / check (or 75 Stars) | OFAC + EU/UN/OFSI | Yes (paid) | P2P, freelancers, small business needing proof |
| 2 | AMLBot | No | From $0.20 / check | OFAC + sanctions | No | High-volume traders, no docs needed |
| 3 | Scorechain platform | No | From €500 / month | OFAC + EU/UN, monitoring | Yes | Compliance teams, exchanges |
| 4 | Chainalysis KYT | No | Enterprise (from $50,000/yr) | Full, industry standard | Yes | Licensed exchanges, banks |
| 5 | Crystal Blockchain | No | Enterprise (contact) | Full, law-enforcement grade | Yes | Investigations, regulators |
Figures for @scorechain_amlbot, AMLBot and Scorechain are taken from the products' own published tiers. Enterprise pricing for Chainalysis and Crystal is described in general terms only — contact those vendors for exact quotes. Free tools do point-in-time checks; enterprise tools add continuous monitoring.
This is the default when you want a real answer at zero cost. The free tier gives 3 checks per day with no registration, and each one returns the same full screen as the paid version: a 0-100 risk score plus a category breakdown across the OFAC SDN list, EU/UN/OFSI sanctions, darknet-market exposure, mixer history (including Tornado Cash) and ransomware cluster links. It works across 25+ chains including ETH, BTC, TRX (with USDT TRC-20), BNB, XRP and Polygon.
What makes a free bot trustworthy is accuracy: in testing against Chainalysis KYT (the enterprise standard used by Coinbase and Binance) on 40 shared addresses, it matched results in 37 of 40 cases — 92.5% accuracy. The same engine runs in a browser at cryptoaml.ai if you'd rather not use Telegram. You only step into paid territory ($0.50/check, or 75 Telegram Stars) when you need more than three checks a day or a downloadable PDF report.

No free tier, but the per-check price (from $0.20) is the lowest available once you screen at volume. Results appear in chat only — no downloadable report — so it suits high-volume CIS-region P2P traders who don't need a paper trail.
From $0.20/checkNo PDFHigh volume
The enterprise product behind the bot. Once your volume passes a couple hundred checks a day, or you need continuous monitoring, bulk API access and legally admissible reports, this is the step up (from €500/month). The Telegram bot is effectively a free entry point to the same data.
Chainalysis (used by Coinbase, Binance, most regulated exchanges; publicly described from around $50,000/year) sets the benchmark others are measured against — and the 92.5% match rate is exactly why the free bot is credible for spot checks. Crystal Blockchain is law-enforcement grade, used by investigators and national agencies. Both are enterprise-only and overkill for screening a single wallet.
Below those three lines, the free tier of @scorechain_amlbot genuinely covers a freelancer accepting crypto or a P2P trader doing due diligence.
An AML check doesn't just look up one list. It traces the transaction graph behind an address — who funded it, and where those funds came from. Each upstream source is tagged (exchange, darknet, mixer, gambling, sanctions), and the weighted share of high-risk exposure becomes the 0-100 score. Above 70 typically means manual review or refusal. The data behind a good check includes the OFAC SDN list (14,000+ sanctioned crypto addresses as of 2026), the EU consolidated list, UK OFSI, UN sanctions, darknet clusters, mixer clusters and ransomware wallets — and that same data feeds both the free and paid checks.
Yes — @scorechain_amlbot (and cryptoaml.ai) gives 3 free checks/day, no registration, each with the full OFAC, sanctions, darknet and mixer breakdown.
For individuals, mostly quantity and documentation, not depth. Free = 3 full checks/day. Paid ($0.50/check) removes the cap and adds a downloadable PDF. Enterprise tiers add monitoring and API.
When you exceed ~3 checks/day, need a PDF to prove you screened, or run a business needing monitoring and API.
@scorechain_amlbot — screens the OFAC SDN list (14,000+ addresses) plus EU/UN/OFSI in one check, 25+ chains, 92.5% match vs Chainalysis.
@scorechain_amlbot requires no registration and stores no personal data — the address is passed to the engine and the result returned, like a block explorer.
