Sec Api Rate Limits

SEC API (sec-api.io) governs throughput with per-second request limits that scale by subscription tier, plus a monthly free data-download allowance. On the Personal & Startups tier the Query API is limited to 20 requests/second; on Business Internal Use the Query API rises to 40 requests/second and the Full-Text Search API is limited to 20 requests/second. The Free Trial is a one-time 100-call allocation rather than a per-second limit. Enterprise rate limits are customizable. The real-time Filing Stream API is a push WebSocket and is not governed by a per-request rate limit. Numbers were grounded against the sec-api.io pricing page on 2026-07-11; verify current values before relying on them.

Policies

Backoff Strategy
On a 429 response, back off with exponential delay and jitter before retrying, and stay within your plan's per-second limit.
WebSocket Keepalive
The Filing Stream server sends a ping every 25 seconds and expects a pong within 5 seconds; respond to pings (most libraries do so automatically) to avoid disconnection.
