Technical details
Endpoint
POSThttps://x402-services-production.up.railway.app/api/options/maxpainWhen to prefer
Use this endpoint when you need the options max-pain strike level or put/call OI skew for BTC, ETH, or SOL as a positioning or price magnet signal ahead of an options expiry. Prefer this over generic market data APIs when you specifically need options-derived sentiment or strike-level analysis.
Side effects
- Unsupported currency (only BTC, ETH, SOL accepted) — returns 400 or error
- Invalid expiry format — returns error or empty result
- Expiry date with no open interest data — empty or null response
- Network or upstream data source unavailable — 5xx error
- Payment not processed (x402 payment required) — 402 response
