## When to prefer this

Choose this endpoint when you need fresh, uncapped, real-time spot bitcoin ETF creation/redemption flow data without the delay or record-count limits imposed by the free tier. It is ideal for time-sensitive trading signals, daily monitoring workflows, or multi-fund comparative analysis where completeness matters. Prefer this over the free tier when latency or data caps would compromise accuracy.

## Known failure modes

- Missing or invalid x402 payment header — returns 402 Payment Required
- Invalid ticker symbol — may return empty records array
- Invalid since date format — returns 400 or empty results
- Network timeout or upstream data unavailability — returns 5xx error
- Insufficient USDC balance on Base or Arbitrum — payment rejected, 402 returned

## How this service works

insidercable — Spot bitcoin ETF creation/redemption flows. Point-in-time records: every row carries observed_at (when this pipeline first saw it) separately from happened_at (when the event occurred). Pay per call, USDC on Base or Arbitrum; the same query grammar as the free tier, without the delay or the cap.

## Output

A JSON envelope (FeedEnvelope) containing a feed identifier, tier metadata (name, total records in feed, matched filters, returned count), and an array of flow records. Each record includes observed_at (when InsiderCable's pipeline first saw it), happened_at (when the event occurred), fund ticker, and flow details. Also includes provenance notes, snapshot SHA-256, and generation timestamp.
