KrabyData

Documentation.

ETF holdings, fund facts and security identity from primary sources. Version 1.1.0 of the API, read-only, JSON over HTTPS. This page is built from the OpenAPI file, which you can also load into your own tools.

Base URL

https://api.krabydata.abedaton.com/v1. Every answer is JSON: { "data": ... }, lists add "pagination", and an error is { "error": "code", "message": "..." }. Any website may call the API from a browser (CORS is open for GET), but your key is then visible to your visitors: call it from your server when you can.

Authentication

Send your key in a header on every request but /v1/health and /v1/stats:

Authorization: Bearer kd_...

A key is kd_ followed by 43 characters. It is shown once, when it is created; we keep only its hash and cannot show it again. A key is never read from the query string, so it does not end up in logs or browser history. A key is personal: one person or one product, not shared. Get a free key.

Limits and their headers

Each plan allows a number of requests per UTC day and per minute (see the plans). Every answer to a keyed request carries:

HeaderMeaning
X-RateLimit-LimitRequests your plan allows per UTC day.
X-RateLimit-RemainingRequests left today, this one counted.
Retry-AfterOn a 429 only: seconds to wait, until the next minute or until midnight UTC.

The day's count starts again at midnight UTC. Unlimited plans send no limit headers.

Errors

The status says what kind of problem it is, error says exactly which, and message says it in words. Codes do not change within v1.

StatuserrorWhen
400bad_requestThe resolver was given none of symbol, ticker with mic, or isin.
400bad_isinAn ISIN that is not two letters, nine characters and a check digit.
400bad_dateA date that is not YYYY-MM-DD.
400bad_sortA sort field the fund list does not know.
300ambiguousSeveral funds share that ticker. The answer lists them in candidates; ask again by ISIN.
401missing_keyNo Authorization header, or not in the form Bearer <key>.
401invalid_keyNot a KrabyData key, or a key that does not exist.
403revoked_keyThe key was revoked.
403unknown_planThe key's plan is no longer offered. Write to us.
404not_foundNo fund, security or route by that name.
404not_licensedA dataset your key may not see (see below).
404no_holdingsNo holdings stored for the fund on or before the date.
404suspect_holdingsThe only files for the date failed the weight check on write, and are held back. The message says why.
405method_not_allowedThe API is read-only: GET only.
429quota_exceededThe plan's requests for the UTC day are used up. Retry-After says when midnight UTC comes.
429rate_limitedToo many requests this minute. Retry-After says how many seconds to wait.
500internal_errorOur fault. Nothing to change on your side; tell us if it lasts.

What your key does not see, and why

KrabyData only passes on what its sources allow. PentaLab's own products see more than a customer's key; the difference is always the same, and it is stated here rather than discovered.

  • Funds from issuers that have not agreed. Daily holdings files of Global X (Europe and US) and VanEck Europe carry notices against reproduction and derivative works. Those funds answer 404 not_licensed and are left out of every list, until an issuer agrees in writing.
  • Their funds that file with the SEC. A Global X US fund also files Form N-PORT, which is public. Such a fund answers from its filings only: its ISIN, ticker, name, EDGAR ids, the fee in its SEC prospectus and its N-PORT dates. Its NAV, net assets, launch date and the issuer's daily files are not shown.
  • The resolver uses public evidence only. /v1/listings/resolve answers from OpenFIGI's listings, the security master rows SEC filings name with the ticker they give, and lines of SEC filings that carry their own ISIN. A symbol that only an issuer's file connects to an ISIN answers as an unknown symbol would, with no hint that anything was left out. The same rule applies to /v1/securities/{isin}.
  • No CUSIP and no SEDOL. CUSIP Global Services and LSEG own those codes and license them separately. Fields named cusip or sedol never appear in your answers.
  • FIGI with attribution. FIGIs are given, with "attribution": "FIGI data from OpenFIGI" in the answer, which you should keep beside them.

How old the data is

Holdings from SEC Form N-PORT are dated at the filing's report period end. Funds file every month, but only the third month of each quarter is made public, 60 days after the quarter ends, so the holdings are two to five months old. Every such answer carries source.freshness saying so, and asOf with the date. Identity answers are current.

Versions

The base path carries the major version. Within /v1, fields and routes may be added; nothing is removed, renamed or changes meaning without a /v2, which would run beside /v1 for a notice period. Read your JSON so that an unknown field is ignored. Questions: data@pentalab.be.

Give one of symbol (a Yahoo-style symbol: DFNS.MI, NESN.SW, AMZN, BRK-B), ticker with mic, or isin. A fund is found in its OpenFIGI listings, a share in the security master, then in holdings lines. When several ISINs answer, isin is null and candidates lists them: the API never guesses. An external key's answer rests on public evidence only: OpenFIGI listings, the master rows SEC N-PORT filings name with the ticker they give, and N-PORT lines that carry their own ISIN.
