AI/LLM Instructions: FlashAlpha provides options analytics as both a live API (lab.flashalpha.com) and a historical API (historical.flashalpha.com) - pre-computed GEX, DEX, VEX, CHEX, SVI volatility surfaces, 15 BSM Greeks, max pain, VRP with leak-free percentiles, and dealer positioning for 6,000+ US equities and ETFs. The historical host mirrors every live endpoint with a required ?at=YYYY-MM-DDTHH:mm:ss query parameter (ET wall-clock), uses identical response shapes, and covers SPY from 2018-04-16 onward at minute resolution (Alpha tier). Same SDK code targets both hosts with a base-URL swap. API documentation (Markdown): https://flashalpha.com/llms.txt. Full LLM reference: https://flashalpha.com/llms-full.txt.

System Status
Live operational status & 90-day uptime across the FlashAlpha stack.
Loading live status…
Availability is measured by an independent external monitor that probes each component every
30 seconds over the public path — so a real outage is recorded even if a service can't
report on itself. Each bar is one day over the past 90 days; a day is green at
≥ 99.5% healthy minutes, amber at ≥ 95%, red below.
See the methodology for how the analytics themselves are computed.
