What Datajud (BYOK) is for

Datajud (BYOK) lets an AI assistant read your own Datajud data through the Datajud API with a key you supply (Datajud public API key (the part after 'APIKey ')). Read-only: 7 tools (find_case_by_number, search_cases_by_class_and_unit, search_cases_by_class, search_cases_by_subject, search_cases_by_court_unit, search_cases_by_filing_date, page_cases_by_class_and_unit). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api-publica.datajud.cnj.jus.br. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Datajud. Datajud and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "Show case 00008323520184013202 in TRF1"
• "List tax enforcement cases of the DF tax enforcement court unit in TJDFT"
• "Find cases of class 1116 in TJSP"
• "Find cases with subject 6017 in TJDFT"
• "What cases does court unit 13597 of TJDFT handle?"
• "Which cases were filed in TJSP in January 2024?"

What it does

• find_case_by_number: Look up one court case by its unified CNJ case number (20 digits, no punctuation) in a given court. Returns class, subjects, court unit, filing date and the full list of procedural movements. Party names are not part of this data.
• search_cases_by_class_and_unit: Search cases of one procedural class (TPU code, for example 1116 Execucao Fiscal) handled by one court unit (vara or serventia code). Returns case summaries without movements.
• search_cases_by_class: Search cases of one procedural class (TPU code) in a court. Returns case summaries without movements.
• search_cases_by_subject: Search cases that carry one subject (assunto, TPU code) in a court. Returns case summaries without movements.
• search_cases_by_court_unit: Search cases handled by one court unit (vara or serventia code) in a court. Returns case summaries without movements.
• search_cases_by_filing_date: Search cases filed within a date range in a court. Returns case summaries without movements.
• page_cases_by_class_and_unit: Get the next page of cases of a class and court unit with search_after, ordered by index timestamp. Pass 0 for the first page, then the sort value (a number in milliseconds) found on the last hit of the previous page.

BYOK key

You bring your own Datajud Datajud public API key (the part after 'APIKey ') (https://datajud-wiki.cnj.jus.br/api-publica/acesso). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api-publica.datajud.cnj.jus.br over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Datajud (BYOK) — Privacy Policy

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Datajud (BYOK) is. Datajud (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Datajud data: Search metadata of Brazilian court cases (class, subject, court unit, filing date, movements) across federal, state, labour, electoral and military courts with the public Datajud API key. You bring your own Datajud Datajud public API key (the part after 'APIKey '); the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Datajud call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to api-publica.datajud.cnj.jus.br, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Datajud rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What Datajud receives. The request we make on your behalf, including the key and the arguments, under Datajud's own terms and privacy policy. Datajud acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Datajud gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your Datajud data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. Datajud (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at Datajud at any time to end all access.

Children. Datajud (BYOK) is a general-audience service operated by the adult using the assistant, under Datajud's own age rules.

Changes. We will post changes here with a new effective date.
