The docs group the data into twelve datasets under a three-level hierarchy — companies own events, events contain content: companies, events, live audio, live transcripts, backlog audio, backlog transcripts, filings and reports, slide presentations, chapters, summaries, parsed documents and segments. They are bought individually or bundled, and each API key inherits its plan's permissions — a dataset outside it answers `403`. The combined endpoints are all-or-nothing about that: `/documents` needs reports, slides and transcripts together, `/live` needs both live datasets. ## Pricing Nothing is published. The pricing page gives Quartr API a contact-sales button and the phrase "Enterprise & bundle options" where a number would go. No self-serve signup, no free key. The standard terms do state the shape of the deal: a twelve-month initial period unless the order says otherwise, automatic renewal unless you give written notice 30 days before expiry, fees due 30 days from invoice, non-cancellable and non-refundable. Quartr may raise the fee at renewal on 30 days' notice, and a subscription period running past twelve months can be indexed annually — to US CPI-U in the two US contracts and to the EU-wide HICP in the two international ones — with no single adjustment exceeding eight per cent. A free evaluation period exists at Quartr's discretion, with the warranties and the indemnity switched off for it. ## Data & coverage 16,000-plus companies across 65 markets and 50m-plus documents, per the vendor's own API pages. Archive depth is not published anywhere. The docs describe the delivery SLAs as contractual: live content streamed and transcribed within five seconds of event start for 90% of events, transcripts for 95% within 45 minutes of the call ending, audio for 90% within 20 minutes, filings within 15 minutes of release, slides within 30 minutes, edited transcripts within a couple of hours. Snowflake shares refresh daily. Audio comes as MPEG and M3U8 from a CDN with no second authentication step, backlog transcripts as JSON, reports and slides as PDFs with parsed machine-readable text behind its own licensed permission. Live transcripts stream as JSON Lines with per-word timings, confidence scores and `[indiscernible]` markers. Companies match on ticker, ISIN, CIK or OpenFIGI, but only the companies endpoint returns those identifiers — everything else gives you `companyId` and expects you to map it. Default rate limit is 50 requests a second. ## Integrations Three routes to the same data: REST at version 3, signed webhooks for created, updated and deleted records, and a Snowflake private listing a Quartr representative provisions against your account identifier. There is no SDK in any language — the docs name none — so the integration is HTTP you write yourself. Quartr MCP is a Quartr Pro feature and not part of this product. ## Limitations - **Redistribution is a different contract, not a larger plan.** Quartr publishes four sets of API terms — internal use and redistribution, each in a US and an international version — and the one you sign decides what the data is for. - **Under internal use, quoting is metered by word count.** Derived work leaves your firm only if it is a meaningful transformation, no continuous verbatim excerpt from one document exceeds 250 words, and verbatim Quartr material does not exceed 20% of the total word count. - **Under redistribution, the data goes into one named product** set out in the order and nowhere else, a Quartr logo and link must appear wherever it is displayed, and where Quartr cannot measure usage itself you owe monthly reports of what each unique user accessed, when, and whether the interaction was retrieval, summarisation or generation. Your own end users inherit the 250-word and 20% limits through Quartr's downstream data-use terms. - **Neither contract lets you train on it.** No training, fine-tuning, evaluating or otherwise developing any AI or ML model on the data; an AI service may take it as input only if it does not retain the inputs or train on them. Scraping, bulk downloading, systematically caching and building a database or dataset out of the data are prohibited separately, beyond whatever the permitted purpose or the Approved Product allows. - **Nothing survives cancellation.** On termination you delete, destroy or return all Quartr data, and on Quartr's request provide written certification signed by an authorised representative that you did, keeping copies only as law or a bona fide retention policy requires. - **Transcripts exist only for events conducted in English** — a large hole in a 65-market product. Speaker identification is prioritised by client interest during earnings season, the name, role and company fields can be null, and older transcripts are never backfilled with it. - **No prices, estimates or financial statements.** This is documents and audio about companies, not numbers out of them, and the one structured financial dataset — segments — is marked Legacy, covers only the S&P 500 and is explicitly "not offered to new partners". - Support is your Quartr representative, 9:00–17:00 CET on weekdays, and nowhere public. The published API changelog's most recent entry is dated 18 December 2025. ## Alternatives [AlphaSense](https://stockmarketstack.com/tools/alphasense) sells a comparable corpus with an API and the same quote-only motion, plus broker research Quartr has none of. [Fiscal.ai](https://stockmarketstack.com/tools/fiscal-ai) adds the financial statements missing here, and [Daloopa](https://stockmarketstack.com/tools/daloopa) is the opposite trade — numbers extracted out of the same filings rather than the documents themselves. The sibling product, [Quartr](https://stockmarketstack.com/tools/quartr), is the app a human reads; this card is the feed. Compare it against the rest of the [fundamentals and research platforms](https://stockmarketstack.com/categories/fundamentals-research). ## FAQ ### Is the Quartr API included in a Quartr Pro subscription? No. It is a separate product on its own contract, and the two are listed as separate line items on the vendor's own pricing page. Quartr MCP is the one that comes with Pro; the API is sold to engineering teams building something else on the data. ### How much does the Quartr API cost? Quartr publishes no figure. The pricing page carries a contact-sales form and the words "Enterprise & bundle options" and nothing more. What the standard terms do fix is the shape of the deal — a twelve-month initial period, automatic renewal unless you give 30 days' notice, fees due 30 days from invoice, and no refunds. ### Can I show Quartr transcripts inside my own product? Only under the redistribution contract, which is a different document from the internal-use one. It licenses the data into one named product set out in the order, requires a Quartr logo and link wherever the data is displayed, and, where Quartr cannot track usage itself, obliges you to send monthly usage reports naming what each unique user touched, when, and how many authorised users you have. ### Can I train a model on Quartr data? No, under either contract. Both ban using the data to train, fine-tune, evaluate or otherwise develop any AI, machine-learning or large-language model. Passing data into an AI service as input is allowed only where that service does not retain the inputs or use them for training. ## Also from Quartr - [Quartr](https://stockmarketstack.com/tools/quartr.md) ## Also worth comparing - [BamSEC](https://stockmarketstack.com/tools/bamsec.md) — SEC filings and earnings transcripts, relabelled, searchable and downloadable to Excel. - [sec-api.io](https://stockmarketstack.com/tools/sec-api-io.md) — Every EDGAR filing since 1993 as JSON, plus a websocket push of new ones. - [SEC EDGAR](https://stockmarketstack.com/tools/sec-edgar.md) — Every US filing since 1994, free and keyless — the limit is ten requests a second. - [Daloopa](https://stockmarketstack.com/tools/daloopa.md) — Filings and slide-deck KPIs, machine-extracted and dropped into your own Excel model. - [Fiscal.ai](https://stockmarketstack.com/tools/fiscal-ai.md) — Filings, transcripts and 20-year financials, in a terminal or through an MCP server. - [GuruFocus](https://stockmarketstack.com/tools/gurufocus.md) — Thirty years of financials, a deep screener and 13F guru portfolios, sold by region.
