COMPARISON

Filingrail vs the free SEC EDGAR API

The SEC's EDGAR API is free, public-domain, and canonical — so the honest question isn't “which has better data” (it's the same data), it's “is the parsing worth $9 a month?” This lays out exactly what you build and maintain yourself against raw EDGAR, and what Filingrail hands you already done.

Plain facts in both columns. Where a value depends on the other provider’s current plan, we say so rather than pin a number that might drift — verify the live figures on their own pricing page before you commit.

AT A GLANCE

The short version

Both read from the same source — SEC EDGAR. The difference is labor: EDGAR gives you raw XBRL, submission JSON, and a rate limiter to respect; you write the parser, the deduper, the ticker-to-CIK resolver, and the Form 4 / 8-K / 13F extractors. Filingrail is that work already done, as one clean JSON envelope with a link back to the source filing on every response. If you enjoy owning the pipeline, EDGAR is free and yours. If you'd rather skip weeks of parser maintenance, that's the trade.

SIDE BY SIDE

Filingrail and SEC EDGAR API, dimension by dimension

Comparison of Filingrail and SEC EDGAR API.
Dimension Filingrail SEC EDGAR API
Price Free tier $0 (50 requests/day). Paid $9 / $49 / $199 per month for 5k / 50k / 500k requests. Free. Public-domain U.S. government data, no cost and no key.
What you build yourself Nothing — the parser, deduper, rate-limit governor, and ticker→CIK resolver are already built. An XBRL parser, a restatement deduper, a SEC fair-access rate limiter, ticker→CIK resolution, and Form 4 / 8-K / 13F extraction — all yours to write and maintain.
Response shape One consistent JSON envelope (data + meta) across all endpoints. Typed, USD-normalized. Raw XBRL company-facts JSON, submission JSON, and the frames API — each a different shape, mixed units, dimensional contexts to decode.
Insider trades / 8-K / 13F Parsed endpoints: Form 4 transactions, 8-K item codes, 13F holdings — one row each, ready to query. The raw filings are there, but you parse the Form 4 / 8-K / 13F documents yourself; EDGAR does not hand you structured rows.
Source traceability filing_url on every record (meta.source_filing_url on company financials) — a link straight to the filing on sec.gov. EDGAR is the source, so provenance is inherent — you just have to track which filing each number came from yourself.
Rate limits Per-tier request quotas metered by RapidAPI; no need to pace EDGAR yourself. SEC fair-access policy (~10 requests/second) with a required declared User-Agent — you implement the throttling.
Freshness Refreshed daily from EDGAR; meta.as_of on every response. Real-time — it is EDGAR. Newest filings the moment they are accepted.
MCP / agent support First-party MCP server (pip install filingrail-mcp) — drops into Claude Desktop, Cursor, or any MCP client. None — a raw REST/JSON surface; you write any agent integration.
Support Async email, same business day. Self-serve documentation only.

HONEST CALL

When each one is the better fit

Pick Filingrail when…

  • You'd rather not write and maintain an XBRL parser, a restatement deduper, and a SEC rate-limit governor.
  • You want Form 4 insider trades, 8-K events, and 13F holdings as structured rows instead of raw filings to parse.
  • You want one consistent JSON shape and a source-filing URL on every response.
  • You want to drop SEC data into an AI agent via MCP with no glue code.

Pick SEC EDGAR API when…

  • It's free and you're happy owning the full pipeline end to end.
  • You need a filing type or field Filingrail does not parse, and want direct access to the raw document.
  • You need real-time, the-instant-it-is-accepted freshness rather than a daily refresh.
  • Your volume or budget makes running your own EDGAR client the obvious call.

Common questions

Isn't the SEC EDGAR API free? Why pay for Filingrail?
Yes — EDGAR is free, public-domain U.S. government data, and if you already run your own EDGAR client you don't need Filingrail. What you pay for is the parsing: an XBRL normalizer, a restatement deduper, a fair-access rate limiter, ticker-to-CIK resolution, and Form 4 / 8-K / 13F extraction — built once and maintained for you. If that's a few weeks you'd rather not spend, $9/mo is the trade. If it isn't, EDGAR is free and the samples let you decide.
What does Filingrail do that EDGAR's API doesn't?
EDGAR gives you raw XBRL company-facts JSON, submission JSON, and the frames API — accurate but unnormalized, in mixed units, with dimensional contexts to decode. Filingrail normalizes financial statements to one consistent typed set of fields in USD, and adds parsed endpoints for Form 4 insider trades, 8-K item-coded events, and 13F holdings that EDGAR only exposes as raw filings. Every Filingrail record also carries a link to the filing it came from — filing_url per record, or meta.source_filing_url on company financials — so you can open the original.
Is it the same underlying data?
Yes. Filingrail reads from SEC EDGAR — the same canonical public filings — with a compliant User-Agent and inside SEC's fair-access limits. Nothing is invented or sourced from a third-party broker; every figure reconciles to the filing it came from, which is exactly why a source-filing link is on every record.
Can I use both — EDGAR directly and Filingrail?
Absolutely. Many teams use Filingrail for the normalized, high-frequency work (financials, insider, 8-K, 13F) and hit EDGAR directly for a niche filing type or a document Filingrail does not parse. They read the same source, so the numbers line up.
How fresh is Filingrail compared to EDGAR itself?
EDGAR is real-time by definition. Filingrail refreshes daily from EDGAR — new filings appear after the daily ingest window, and meta.as_of tells you exactly how fresh a response is. If you need the-instant-it-is-filed latency as a hard requirement, read EDGAR directly.
