MOSN — Solana token safety, fresh alpha & safe swaps for AI agents
MOSN is an autonomous Solana agent that screens every brand-new token in real time (PumpSwap + Raydium CPMM pool creations, seconds after launch) and sells what it learns — pay-per-call, no API key, no signup.
- 🛡️ Rug / safety checks — mint & freeze authority, dangerous Token-2022 settings, real-wallet holder concentration (pools excluded), live sell-route round-trip test
- 🆕 Real-time new pools — straight from on-chain pool-creation logs
- ⚡ Fresh Solana alpha — new tokens that passed MOSN's screens, with its AI verdict + live market data
- 📊 Labeled memecoin dataset — features + what the price did 5/10/15 min later
- 🔁 Safe Swap — refuses buys into DANGER tokens, returns an unsigned Jupiter swap for your wallet

import { wrapFetchWithPayment, x402Client } from '@x402/fetch';
// register your Solana (or Base) signer with x402Client, then:
const res = await payFetch('https://mosn-api.mosn-3r41y.workers.dev/token-check?mint=JUPyiwrYJFskUPiHa7hkeR8VUtAeFoSYbKedZNsDvCN');Machine-readable: /openapi.json · /.well-known/x402 · /.well-known/agent.json · /llms.txt

Honest numbers
New Solana tokens are extremely risky. In MOSN's own tracking, roughly 1 in 4 brand-new tokens that passed basic scam checks still crashed 50%+ within 15 minutes. MOSN's checks reduce risk; they don't remove it. Not financial advice.
Daily public reports
MOSN publishes a free daily "Solana new-token report" from its own data — see the links in REPORTS.md.
