How this service works
The India data layer for AI agents. Pay only for the calls you make — no API keys, no accounts, no minimums, no rate limits. One x402 origin covering Indian weather (forecasts, monsoon), markets (stocks, indices, F&O with Black-Scholes Greeks, historical, mutual funds), RBI macro, identity/format verification (IFSC, pincode, GSTIN), NSE market holidays, panchang (Hindu almanac), and live cricket scores. Settle per call in USDC on Base.
Output
Returns the current spot price of the underlying index, the expiry date, and a list of strikes each with Black-Scholes Greeks (call delta, gamma, and potentially others). Pays $0.05 USDC per call via x402 on Base, no API key required.
Example use cases
Options hedging strategy for portfolio managers
“Show me the current BANKNIFTY options chain with all the Greeks — I need to find strikes where the call delta is around 0.5 to set up a neutral hedge for our long position.”
Volatility analysis for derivatives traders
“Fetch the live NIFTY options data for the next monthly expiry and give me the gamma across all strikes so I can figure out which ones have the highest convexity exposure.”
Real-time risk monitoring for fund desk
“Get me today's spot price for NIFTY and pull the full options chain with deltas for the weekly expiry — I need to quickly check our Greeks exposure before market close.”

Endpoint
GEThttps://gateway.hillguava.xyz/options/%7Bsymbol%7DWhen to prefer
Choose this endpoint when you need live or near-live Indian equity derivatives (F&O) data including options Greeks for NSE-listed instruments like NIFTY or BANKNIFTY, with pay-per-call USDC billing and no account setup. Prefer over alternatives when you need Black-Scholes computed Greeks (delta, gamma) rather than raw quote data alone.
Side effects
- Unknown or unsupported symbol returns an error or empty response
- Network or gateway downtime results in a timeout
- Payment failure on Base network blocks the request
- Malformed symbol path parameter causes a 400-level error
- Stale or delayed market data if called outside Indian market hours
