How this service works
108+ receipt-backed x402 work products for AI agents. Clear prices, spend caps, buyer metadata, and structured results over Base USDC.
Output
Returns a JSON object with: an array of filing rows matching the query window, a boolean spike flag indicating whether velocity is anomalous, the filings count in the last hour, the 24-hour mean filing rate, and a ratio comparing current to baseline velocity (e.g. ratio 3.8 means 3.8x normal rate).
Example use cases
Pre-market earnings anomaly alert
“Have there been any abnormal bursts of SEC 8-K filings in the last 12 hours? Show me up to 50 filings and flag it if the velocity ratio looks suspicious.”
Real-time market event surveillance
“I want to know if companies are filing an unusual number of 8-K material event reports right now — check the last 6 hours, up to 200 filings, and only flag items with an anomaly score of 0.7 or higher.”
Daily OSINT briefing on SEC activity
“As part of my morning briefing, check whether 8-K filing velocity over the past 48 hours is spiking above the 24-hour mean — use a limit of 100 and default anomaly threshold.”

Endpoint
POSThttps://agenttoll.dev/paid/osint/sec-8k-velocityWhen to prefer
Use this endpoint when you need real-time or near-real-time anomaly detection on SEC 8-K filing rates rather than retrieving specific filings by company or ticker. Prefer this over general SEC search APIs when the goal is velocity monitoring and spike detection across all filers, not document retrieval. Best suited for market surveillance agents, OSINT pipelines, or trading signal workflows that need a cheap ($0.03), pay-per-call trigger for abnormal disclosure activity.
Side effects
- Invalid hours value outside 1–72 range returns validation error
- Limit outside 10–200 range returns schema validation error
- min_score outside 0–1 returns validation error
- Payment failure via x402 returns 402 Payment Required
- Empty rows array returned when no filings match the window
- Service unavailable if SEC EDGAR upstream is down
