How this service works
100+ paid x402 MCP tools for AI agents. Prediction markets, SEC filings, federal data, OSINT, academic research, health, environmental. Pay per call in USDC on Base.
Output
Returns a JSON object with: a list of matching 8-K filing rows, the current velocity ratio (e.g. 3.8x above baseline), a boolean spike flag, the mean 24-hour filing rate, and the count of filings in the last hour. Allows agents to quickly determine if 8-K filing activity is statistically anomalous.
Example use cases
Pre-market corporate event alert
“It's 8am — check the last 6 hours of SEC 8-K filings and tell me if there's an abnormal spike that might signal a major corporate event. I want up to 50 results and flag anything with an anomaly score above 0.5.”
Overnight regulatory disclosure surge
“Did any unusual burst of 8-K filings happen overnight? Check the last 12 hours, limit to 100 filings, and only show me if the velocity ratio looks like a real spike.”
Real-time market surveillance trigger
“I'm running a trading watchlist — scan the last 1 hour of 8-K filings for velocity anomalies with a minimum score of 0.8 and tell me if a spike is detected so I can investigate.”

Endpoint
POSThttps://tollbooth.memerhuwhite.workers.dev/paid/osint/sec-8k-velocityWhen to prefer
Use this endpoint when you need real-time or near-real-time statistical anomaly detection on SEC 8-K filing rates rather than fetching individual filings. Prefer this over raw EDGAR search when the goal is surveillance, alerting, or detecting market-moving disclosure bursts — especially in automated trading, OSINT pipelines, or news event detection workflows. It is specifically designed for velocity analysis, not document retrieval.
Side effects
- Invalid hours value outside 1-72 range returns validation error
- limit below 10 or above 200 rejected with schema error
- min_score outside 0-1 range causes rejection
- No filings found returns empty rows array with spike:false
- Upstream SEC EDGAR data unavailability may return stale or error response
- Payment failure (insufficient USDC) blocks the call entirely
