Is this your product? Claim it to see how agents find it: lookups through the API, MCP and letme, the comparisons it's in, and what people search for in Markets. Free, and it never changes the grade. Or verify it, or log in if it's already claimed.
Assessment. Exchange-level tick and order book data metered per GB, with published per-IP rate limits, Retry-After on 429, dated release notes and clients in three languages. The HTTP API is still at major version 0, the status page lists two critical and several major incidents in 90 days, there is no OpenAPI document, and the legal pages were unreadable.

Plus $1,750 a month in licence fees, annual contract, external distribution and dedicated connectivity. Unlimited $4,500 a month in licence fees, annual contract, 16 or more years in all schemas.

- Legal entity
- Databento, Inc., per the about page footer and the GitHub organisation; the terms could not be read
Facts verified 3 November 2026 from vendor docs, repositories and package registries. JSON · Markdown
Strengths
- Per-IP rate limits published with numbers, 429 with Retry-After, and a documented error format with a code, a message and a docs link
metadata.get_costquotes a request before it is billed, batch jobs are billed once with 30 days of re-download, and a monthly historical spending limit can be set in the portal- Dated release notes per component with breaking changes and deprecations called out, and Python 0.85.0 to 0.89.0 released between 25 August and 28 October 2026
- Up to 100 named API keys per account with rotation, per-member permissions, and keys found in public revoked by the vendor
- $125 of credits at signup and metered historical pricing with no subscription; metadata and symbology calls are free
Weaknesses
- Two critical and several major incidents on the status page in the 90 days to 3 November 2026, mostly Historical API outages and batch job delays
- The HTTP API is at major version 0 and the docs say it is not considered stable
- No OpenAPI document; per-GB rates sit in the portal catalogue behind a login, and the pricing page shows plans only
- The terms and privacy policy are drawn by script and could not be read, and no security.txt, SOC 2 or ISO 27001 was found
- Live data and the Plus and Unlimited plans need a subscription on an annual contract by sales, and signup is in a browser
Before you call it notes for agents
- Call
metadata.get_costbeforetimeseries.get_range, and set a monthly historical limit in the portal; a duplicate streaming request is charged twice - Send the key as the Basic auth username (
-u $DATABENTO_API_KEY:) to hist.databento.com/v0; never put it in the URL or source code - On 429 wait for the Retry-After header; keep under 100 time series requests a second and 20 batch submissions a minute per IP
- Check status.databento.com before retrying a slow or 504 Historical request, since several incidents since August were API outages or batch delays
- Use batch download for requests over 5 GB, split by time range or
limit, and readschemaandstype_infrom the dataset page before querying

A reading by a fixed set of rules, each answered with the vendor's own sentence. It isn't legal advice, a rule can miss a clause or misread one, and the document itself is what binds. How it's read and scored.
Databento, Inc. is named in the about page footer and as the GitHub organisation's name. The legal pages at databento.com/legal, /legal/terms and /legal/privacy answer 200 with a script shell and no text, so the terms, privacy policy, legal entity details and any automated-access clause are unread.
databento.com/robots.txt disallows only /portal for all crawlers. status.databento.com and roadmap.databento.com allow reading.
RDAP for databento.com was refused (403 from rdap.org), so the registration date is unchecked.
/.well-known/security.txt returns 404.
The status page is an Atlassian Statuspage at status.databento.com with Portal, Historical, FTP and seven live-feed components.
Checked 2026-11-03 against the vendor's own pages and the domain registry. Provenance is half of Transparency & trust.

Researched 3 November 2026 from public pages. The about page names Christina Qi as Co-founder and CEO and lists the rest of the team by function (API, core, data and systems engineering, SRE, product, people, marketing) without naming any other co-founder, so only she is listed; the roster of founders may be incomplete. The page links no personal accounts. The about page gives the company's own LinkedIn, X, GitHub, YouTube and Slack links, and the support page gives support@databento.com and Intercom chat. Funding from the about page timeline (Series A in November 2021 with over $27 million raised in initial rounds, Series B in July 2026 for $97 million) and the Series B blog post, which names the lead and participating investors; a 2024 Series A+ post of $10 million exists on the blog but its body was not parsed, so its investors aren't attributed to that round.

Notable
- Rate limits per IP are published for the Historical API, 100 concurrent connections, 100 time series and 100 symbology requests a second, 20 metadata and 20 batch list requests a second, 20 batch submissions a minute, with 429 and a Retry-After header source

- Statuspage at status.databento.com with ten components. The 90 days to 3 November 2026 hold two critical incidents (portal and Historical API down on 6 August, live authentication timeouts in NY4 on 28 August), several major ones (batch job delays of about two days on 6 and 12 October, a six-hour GLBX.MDP3 delay on 6 October) and a Frankfurt outage opened on 2 November still in monitoring source
- Python client 0.89.0 released 28 October 2026, with 0.85.0 to 0.88.0 between 25 August and 21 October; Rust 0.64.0 and C++ 0.69.0 on 27 October source
- The terms and privacy policy at databento.com/legal/terms and /legal/privacy are drawn by script and returned no text to our reader, so they are unread (checked 2026-11-03)
- The about page lists the company's backers and a $97 million Series B of July 2026 led by New Enterprise Associates; the blog post names 12 participating funds source

Score breakdown methodology v0.7 · October 2026 research run

The incident feed for the 90 days to 3 November 2026 lists a critical outage of the portal and Historical API on 6 August lasting about eight hours, critical live authentication timeouts in NY4 on 28 August for about seven hours, major batch job delays of about two days each opened on 6 and 12 October, a six-hour GLBX.MDP3 delay in the Historical API on 6 October, and a Frankfurt outage affecting XEUR and XEEE opened on 2 November and still in monitoring. Several majors (0 of 30). Per-IP limits are published with numbers (15). 429 with a Retry-After header and a code to sleep on it; streams cut off aren't billed for unsent data, batch jobs are billed once (15).

Graded 60.3 C methodology v0.7
Fix list 18 items, the biggest gain first
Everything this grade says the listing lacks, from the reasons above, the checklist, the provenance checks, the deductions, what we couldn't check and what the review panel asked for, with the steps, ready to paste into a coding agent working on Databento. A fix counts at the next check, once it's public.
You're lucky. As part of the beta, your first month is free.
What we couldn't check
- unchecked: the terms and privacy policy at databento.com/legal/terms and /legal/privacy, which are drawn by script and returned no text, so the entity details, retention, subprocessors and any automated-access clause are unread
- Whether a card is needed at signup to use the $125 of credits
- The per-GB rates per dataset, which sit in the portal catalogue behind a login
- Whether an SLA exists for Plus or Unlimited customers, which the readable pages don't say
- unchecked: GitHub issue responsiveness and CI on databento-python, since the GitHub API rate limit was reached
- unchecked: the domain registration date, because rdap.org answered 403
