On-chain Forensics · alerts
Know the moment a token you hold gets riskier.
One email when a watchlist token's grade drops, or a red flag appears: readable supply lost, liquidity drained, holder concentration spiking. Plus a daily digest of what turned risky across Base and Ethereum. Same deterministic grading engine the verdict API runs, delivered instead of queried.
$29 / 30 daysDaily digest plus same-day red flags, up to 50 tokens on your watchlist.

What lands in your inbox
- Same day: a watched token drops a full grade. The subject line names it and says how far.
- Daily 07:00 CT: everything on your list that got worse, plus the wider feed's new F grades.
- Quiet by default: no email when nothing changed. No newsletter, no upsell spam.
How to subscribe
Payment is USDC on Base over x402, the same rail the rest of this API settles on. The email is required before payment, so you cannot pay for alerts we cannot deliver.
curl -X POST "https://api.onchainforensics.dev/functions/alertsSubscribe" \
-H "Content-Type: application/json" \
-d '{"email":"you@example.com","plan":"month","watchlist":["0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913"]}'
That returns a 402 challenge for $29.00. Pay it with any x402 client and you get back an alerts_key and an expires_at. Check status any time:
curl -X POST "https://api.onchainforensics.dev/functions/alertsSubscribe" \
-H "Content-Type: application/json" -H "X-Alerts-Key: fxa_..." \
-d '{"action":"status"}'
No custodial account, no card on file. USDC in, thirty days of alerts out. Renew by paying again with the same email; the subscription extends rather than stacking.
Why trust the grade
- Deterministic rules over live chain reads: readable supply, transfer activity, holder spread, mint and freeze authority.
- No LLM in the loop, so the same token grades the same way twice.
- Grades A to F with a 0 to 100 activity score, refreshed every five minutes for 400+ tokens.
