How fresh is it, and where does the data come from?

The fastest source behind this answer can change every 15 minutes, so every response carries a refresh_after timestamp — right now it would be 2026-09-22T12:15:00.000Z. Schedule the next call on that value rather than on a guess.

• SEC EDGAR (US federal public domain) — upstream: https://efts.sec.gov

Method version 0.1.0 · serving cache 0 days · every response carries a result_id you can resolve at /v1/provenance.

What should you call next?

• sec_earnings_recent — The releases themselves with their figures ($0.02)

When should you use it?

A polling loop that needs to know whether any issuer has reported, cheaply, before deciding to buy the feed.

What you skip building

• full-feed polling
• row parsing to discover nothing changed
• cursor bookkeeping against EDGAR

When should you not use it?

One-off questions about a named issuer — /v1/sec/earnings/latest answers those. Backfills — cursors are clamped to 7 days; fetch the feed instead.

Where else can you find this?

• Catalog entry (JSON, free)
• OpenAPI schema — input and output types, prices, the 402 flow
