Pricing for point-in-time SEC fundamentals
Plans are priced per organization, not per seat, and billed in advance in U.S. dollars. Every plan gates on how many companies you can query, how fast you can query them and which capabilities are enabled. Any plan can query any as-of date.
Annual billing includes two months free.

One restatement, five ways to use it
Each example follows Axon Enterprise’s FY2024 10-K, filed in February 2025 and amended in May.
DeveloperRestatement alerts
Know what changed and whether it matters
Each restatement arrives by API or signed webhook with a delta for every metric and a materiality score, so a $680M reclassification stands out from a rounding fix.
GrowthUniverse snapshots
Compare a peer set as of one date
Up to 50 companies per request, resolved to one date with no look-ahead, under a single snapshot id you can cite in a backtest.
FreeMCP
Agents see what your pipeline sees
AI agents call the same as-of snapshot over MCP that your code gets over HTTP, down to the snapshot hash.
FreeAudit chain
Trace a figure to its source
Every metric resolves to its filing, the XBRL concept it was read from, how it was mapped and any override applied since.
FreeReplay tokens
Prove what a query returned
Run a query through the query endpoint and it returns a replay token. Hand it to a reviewer and Arche re-runs the query and confirms the result still matches.
Illustrative, in the Arche API’s field names. Amber is the figure as originally filed. Green is what Arche adds.

The guarantees do not change with the plan
Plans differ in coverage, throughput and capability class. Determinism, preserved history and point-in-time retrieval are part of the contract at every tier, including Free.
- Point-in-time retrieval
- Any as-of date, resolved by SEC filing date or by acceptance time.
- Every filing kept as filed
- A 10-K/A is its own filing; the original stays queryable as of its own date.
- Per-value provenance
- Each value carries its XBRL concept, its accession number, and whether it was reported or derived.
- Replay tokens
- A query run through the query endpoint returns a token that reproduces the response exactly.
- MCP access
- An agent calls the same snapshots over MCP that your code gets over HTTP.
- Sandbox keys
- A sandbox key reads the same data as production. Production keys, with their own coverage selection and billing, come with Developer and up.
Do I need a card to use the Free plan?
No. The Free plan needs no payment details and does not expire.
How do I choose the 25 companies on the Free plan?
By querying them. There is no list to fill in first: the first request that reaches a company claims one of your 25 slots, and it stays yours for 30 days after the last request that reached it, so an evaluation in progress never loses the companies it is built around. A company you stop querying frees itself. You can see what you hold, and hand a slot back early, from the coverage endpoints in the API reference.
Can I run a product on the Free plan?
No. The Free plan is for personal, non-commercial use, for evaluation, and for building and testing before you launch. Showing Arche data to the users of your own product, supplying it through an agent that others use, or using it in the course of a business needs a paid plan. The Terms of Service set out what each plan permits.
Can every plan query historical as-of dates?
Yes. Any plan can query any as-of date. Plans differ in coverage, throughput and which capabilities are enabled.
How does annual billing work?
Annual plans are billed once a year in advance at ten times the monthly price, which is two months free compared with paying monthly.
Are taxes included?
All prices are in U.S. dollars and exclude any sales tax or VAT, which is calculated at checkout based on your billing country.
How do renewals and cancellations work?
Paid plans renew automatically for the term you selected until canceled. Cancel at any time from Billing in the developer portal; access continues to the end of the period you have already paid for.
Who processes payments?
Payments are processed by Paddle.com Market Ltd, our merchant of record. See the Refund Policy and Terms of Service.
