Software fabrication
sec-api.io is the established commercial EDGAR API: streaming, parsed filing bodies, XBRL, deep history. If you need those, buy them; this page will not pretend otherwise. But if what you actually need is alerts on new filings, the subscription floor (published plans start around $49/month as of mid-2026) is a lot of money for a watchlist that delivers a handful of filings a week. That slice is what SEC Filing Monitor API sells, at $5 per 1,000 filings with no subscription.
| sec-api.io | SEC Filing Monitor API | |
|---|---|---|
| Pricing model | Subscription; published plans from ~$49 to ~$239/month (mid-2026) | $5 per 1,000 filings returned; empty runs free; no subscription |
| A quiet month costs | The subscription | Cents, or nothing |
| Latency | Real-time streaming/push | Scheduled polling; EDGAR publishes in minutes, your schedule sets the lag |
| Data depth | Parsed bodies, sections, XBRL financials, bulk history | Filing metadata + links to the documents on sec.gov, stable JSON schema |
| Delivery state | You track what you have seen | Managed exactly-once delivery per named monitor |
| Auth | API key | Apify account; no SEC or vendor key |
| AI agents | REST API your agent must be taught | MCP tool via mcp.apify.com; schema-stable tool calls |
| Alerting | Webhooks/streams into your infra | Apify schedules + email/Slack/webhook integrations, no infra |
Choose sec-api.io for sub-minute streaming, parsed financial data, section extraction, or bulk historical research at volumes that justify the plan.
Choose the monitor for watchlists and phrase alerts on a schedule, spiky or occasional workloads, agent tool calls, and any case where a $49/month floor is the wrong shape: a daily 8-K watch on five tickers runs about $0.20-0.30 per month.
