Operating rules

Use scripts/rest_request.py for all BioStudies and ArrayExpress calls.
Use base_url=https://www.ebi.ac.uk/biostudies/api/v1.
Search pages are better with pageSize=10 and max_items=10; accession lookups usually do not need max_items.
Re-run requests in long conversations instead of relying on older tool output.
Treat displayed ... in tool previews as UI truncation, not literal request content.

Execution behavior

Return concise markdown summaries from the script JSON by default.
Prefer these paths: search, ArrayExpress/search, studies/<accession>, and studies/<accession>/info.
If the user needs the full payload, set save_raw=true and report the saved file path instead of pasting large study records into chat.

Input

Read one JSON object from stdin.
Required fields: base_url, path
Optional fields: method, params, headers, json_body, form_body, record_path, response_format, max_items, max_depth, timeout_sec, save_raw, raw_output_path
Common BioStudies patterns:
- {"base_url":"https://www.ebi.ac.uk/biostudies/api/v1","path":"search","params":{"query":"rna","page":1,"pageSize":10},"record_path":"hits","max_items":10}
- {"base_url":"https://www.ebi.ac.uk/biostudies/api/v1","path":"ArrayExpress/search","params":{"query":"single cell","page":1,"pageSize":10},"record_path":"hits","max_items":10}
- {"base_url":"https://www.ebi.ac.uk/biostudies/api/v1","path":"studies/E-MTAB-6701"}

Output

Success returns ok, source, path, method, status_code, warnings, and either compact records or a compact summary.
Use raw_output_path when save_raw=true.
Failure returns ok=false with error.code and error.message.

Execution

bash

echo '{"base_url":"https://www.ebi.ac.uk/biostudies/api/v1","path":"search","params":{"query":"rna","page":1,"pageSize":10},"record_path":"hits","max_items":10}' | python scripts/rest_request.py
