How this service works
Index scores for trading agents — how strong is each major index right now? One read returns the scored index row per book: S&P 500 (SPY) and Nasdaq-100 (QQQ) plus the macro and BTC/ETH crypto books — 0-100 opportunity score, percentile, green/yellow/red light and entry state for each index, with every book's regime verdict alongside. The cheapest top-down read of the whole tape. Refreshed ~5 min in market hours, timestamped. Research, not advice.
Output
Returns one scored row per book: S&P 500 (SPY), Nasdaq-100 (QQQ), macro, and BTC/ETH crypto. Each row includes a 0-100 opportunity score, percentile rank, green/yellow/red signal light, entry state, and regime verdict. Data is refreshed approximately every 5 minutes during market hours and includes a timestamp.
Example use cases
Pre-market regime check across tape
“Before the open, pull the Coil index scores for SPY, QQQ, macro, and crypto — I want to see the opportunity scores and regime verdicts so I know whether the tape is risk-on or risk-off heading into the session.”
BTC and equity signal comparison
“Grab the latest Coil scores for the crypto book alongside SPY and QQQ — show me the opportunity scores, percentiles, and green/yellow/red signals so I can see if crypto and equities are aligned or diverging right now.”
Entry state check before sizing up
“Check the Coil index scores for SPY and QQQ right now — are they in a buy entry state, what are their opportunity scores and percentile ranks, and what does the regime verdict say before I add to my positions?”

Endpoint

Use this endpoint when you need a fast, cheap top-down read of the entire market tape across the four major books (S&P 500, Nasdaq-100, macro, crypto) in a single call. Prefer this over single-name or sector endpoints when doing regime-level or index-level assessment before drilling into individual stocks or sectors.
Side effects
- Payment not included or insufficient (402 Payment Required)
- Service temporarily unavailable during off-market hours (data may be stale)
- Network timeout if endpoint is slow to respond
- Malformed response if data feed is interrupted
