How this service works
Rug protection and decision-ready intelligence for autonomous trading agents. Keyless by design: no signup, no API key — pay a cent per request in USDC (x402). The /alpha/launches LAUNCH RADAR discovers what just launched AND rug-screens every candidate in one call, ranked per-token verdicts — the proactive 'give me safe alpha' call. /vet gives a single-token go/no-go in ONE call by fusing a COMPOSITE rug score (GoPlus static analysis + a LIVE Honeypot.is buy/sell simulation + serial-rugger check) with our SELF-COLLECTED liquidity-drain trend — a rug-in-progress signal that exists nowhere for free because it requires collecting reserves over time. One call is cheaper than the inference tokens you'd burn stitching 4 free APIs, and it stops your agent losing its whole position to a honeypot. Also: /onchain/liquidity drain detector, /screen batch watchlist check, /brief market regime, and raw feeds (prices, stocks, DEX pools, launches, perp funding/OI).
Output
A structured market regime brief for the requested symbol, including macro context signals, trend characterization (e.g. bullish/bearish/risk-off), and any relevant market condition indicators to inform trading decisions.
Example use cases
Pre-trade market context check
“Before I make any trades, give me a market brief for ETH so I know what regime we're in — trending, choppy, or risk-off?”
Automated regime-aware trading logic
“What's the current market regime for SOL? My agent needs to decide whether to enter a long position or stay flat.”
Daily macro briefing for portfolio
“Pull me a market brief for BTC so I have a quick macro read on whether conditions are favorable for holding my crypto positions today.”

Endpoint
GEThttps://x402-seller-m8nx.onrender.com/briefWhen to prefer
Choose this endpoint when an autonomous trading agent needs a single, fast, keyless market regime signal for a specific symbol without stitching together multiple macro data sources. Ideal for agents that make regime-conditional decisions (e.g. only trade in trending markets) and want a $0.03 cost-per-call briefing rather than maintaining subscriptions to multiple data providers.
Side effects
- Invalid or unrecognized symbol returns empty or error response
- Payment failure via x402 if USDC balance is insufficient or wallet not configured
- Stale data if upstream price feeds are delayed
- Generic 500 error if backend service on Render is temporarily unavailable
- Symbol omitted from query returns a generic or default brief
