OSTI.GOV API (U.S. DOE research results)

Use in your agent

Load OSTI.GOV records for a search into pandas and Parquet. Checked against the provider's documentation on Nov 3, 2026.

Access

• No key or account.
• Endpoint https://www.osti.gov/api/v1/records with q, field filters, rows and page; send Accept: application/json (or application/xml, application/x-bibtex).

Request

curl -H 'Accept: application/json' 'https://www.osti.gov/api/v1/records?q=grid-scale+battery+storage&publication_date_start=01/01/2025&rows=100&page=1'

Format

A JSON array of records with osti_id, title, product_type, publication_date, doi, authors, research_orgs, sponsor_orgs, description and links (citation and fulltext). X-Total-Count and Link headers carry paging.

Load into pandas and Parquet

Needs Python 3 with requests, pandas and pyarrow.

"""OSTI.GOV records (DOE-funded research) -> pandas -> Parquet. No key."""
import requests
import pandas as pd

params = {"q": "grid-scale battery storage", "publication_date_start": "01/01/2025", "rows": 100, "page": 1}
r = requests.get("https://www.osti.gov/api/v1/records", params=params,

    "url": next((l.get("href") for l in x.get("links", []) if l.get("rel") == "citation"), None),
} for x in recs]

df.to_parquet("osti_records.parquet", index=False)
print(len(df), "records on this page; X-Total-Count:", r.headers.get("X-Total-Count"))

Run by us on 2026-11-03 (python 3.13.5 | pandas 3.1.0 | pyarrow 26.0.0 | requests 2.34.2). Result: 100 records on this page; X-Total-Count: 1892

Limits

• 20 records per page by default; set rows and page, and follow the Link header rel=next.
• A request rate limit is not stated.

Quirks

• The v1 API is a release candidate and may change before the official v1 release.
• Date filters use MM/DD/YYYY, for example publication_date_start=01/01/2025.

Terms and attribution

• Material may be read, downloaded and analyzed under the Government's reserved rights; doing more needs permission from the authors or publishers.
• OSTI asks AI/ML/LLM projects to contact apis@osti.gov first.
