Search scholarly works with rich query fields and filters

How to use it

Search Crossref scholarly works. Combine a free-text query with field-scoped queries (bibliographic, author, title, container-title, editor, publisher-name, affiliation) and filters (work type, ISSN, ISBN, ORCID, member, prefix, funder, award, subject category, publication/created/deposit/index date ranges, and presence flags for abstract, ORCID, funder, references, license, full text). Sort by relevance, score, publication/index/created/deposit date, or citation/reference counts. Each result is a full work with title, authors, journal, dates, counts, funders, licenses and links. For research-integrity work: `update_type` selects notices of one kind (`is_update` selects notices of any kind), `has_update` selects the papers that were retracted or corrected rather than the notices, and `updates` takes the DOI of a paper and returns the notices about it. Crossref carries whether and when, never why — the stated reason is on retractionwatch/notices.

Errors

• 422 — The request body did not validate Check the fields against this schema. A URN with the wrong prefix is the most common cause.
• 408 — The request ran past its time limit Raise `timeout` in the request body, up to the maximum this endpoint documents. Lowering `count` or turning off the `with_*` flags also helps, because less work finishes sooner.
• 412 — The entity was not found, or a precondition failed Retrying will not help: either the entity does not exist, or the input points at a different one.
• 429 — Too many requests: a rate limit or a usage window is exhausted When the response carries an X-Retry-After header, wait that many seconds and retry: the same number is in the body as `detail.retry_after`, and the limit clears once that window passes. The message in the body names the limit that was hit.
• 500 — Something broke on our side Retrying will not help. If it keeps happening, send us the X-Request-ID from the response headers.
• 529 — Rate limit reached, or the endpoint is overloaded Wait at least 30 seconds, then retry.

Response headers

• X-Error — Error message text (present only on error)
• X-Request-ID — Unique request identifier
• X-Execution-Time — Execution time in seconds
• X-Result-Count — How many records the body carries. 0 means an empty result, which is a normal answer and not by itself an error. A non-zero count can come back together with X-Error when the failure happened partway through — read this header and X-Error independently.
• X-Total-Available-Results — How many records exist for this query, when the endpoint can say. On a `dry_run` request this is the answer and the body is empty. It saturates: the endpoint's documented maximum means 'at least that many', any smaller number is exact.
• X-Warning — Present when the request body carried keys this endpoint does not document. They were ignored, so any filter you meant to apply through them did not apply. Check the spelling against this schema and retry.
• X-Retry-After — Seconds to wait before retrying. Present only on 429.
