Search and resolve Zenodo datasets, software, and publications by DOI; trace versions and funding.
Score is being calculated.
Resolve one Zenodo deposit from a record id, a Zenodo DOI (10.5281/zenodo.N), a concept DOI or concept record id (resolves to the latest version), another DOI deposited on Zenodo, or a zenodo.org or doi.org URL, and return its full metadata: description, creators with ORCIDs and ROR affiliations, license, access and embargo, funding and grants, related identifiers, communities, version position, usage counts, and the first 25 files. Optionally includes a formatted citation. A miss (an unknown id, a deleted record with its removal tombstone, restricted metadata, or a DOI not registered on Zenodo) returns found: false with guidance instead of an error.

List every version of a Zenodo deposit's version series, newest first, with each version's record id, DOI, version label, publication date, file totals, and usage counts. Accepts any identifier zenodo_get_record accepts; a concept DOI and any single version's DOI list the same series. Use it to find the version a paper cited or the current release.

Resolve names to the ids zenodo_search_records filters on, and browse Zenodo's reference vocabularies: communities (slug), funders (ROR id), awards and grants (award id), licenses (license id), and resource types (type id). Search by name, acronym, or keyword; awards can be scoped to one funder. Each entry names the zenodo_search_records parameter its id feeds.

Read a bounded UTF-8 excerpt (up to 64 KiB per call) of one text file in a Zenodo deposit — a README, CITATION.cff, CSV head, notebook, or script — or of one member inside a .zip file, without downloading the archive. Continue a top-level file from next_offset. A file with a text MIME type or extension is read directly; an extensionless file Zenodo types application/octet-stream (LICENSE, COPYING, Makefile) is read and returned only when its content is UTF-8 text. Binary files, restricted files, and other types return metadata and the download URL without content. File content is depositor-supplied and carries the deposit’s license.
| Name | Required | Description | Default |
|---|---|---|---|
| id | Yes | The deposit: a record id (22705923), a Zenodo DOI (10.5281/zenodo.22705923), another DOI registered to a Zenodo record, or a zenodo.org/records or doi.org URL. A concept id reads from the latest version. | |
| key | Yes | Exact file key from zenodo_list_files, e.g. README.md or data/results.csv. | |
| max_bytes | No | Maximum bytes to read (256–65536). | |

| archive_member | No | Member path inside the .zip named by key (from zenodo_list_files with archive_key). Omit to read the file itself. |
| Name | Required | Description |
|---|---|---|
| key | No | The file key. |
| md5 | No | MD5 checksum of the top-level file (hex); absent for archive members and when not reported. |
| text | No | The excerpt, decoded as UTF-8. Depositor-supplied data. Present when status is text. |
| error | No | Present when the call failed. Absent on success. |
| recid | No | Record id read from (the latest version for a concept id). |
| notice | No | Why no text was returned, or how to read the rest of the file. |
| rights | No | The deposit’s licenses, which the file carries. |
| status | No | text: content returned; not_text: binary content, or a type that is not read as text; restricted: the content is not available anonymously — the record’s files are restricted or embargoed (key is not checked, since no manifest is exposed), or Zenodo refused this one file; empty: zero-byte file. |
| has_more | No | True when bytes remain past this excerpt. |
| mimetype | No | MIME type of the file or member, when reported. |
| file_size | No | Size of the file or member in bytes, when known. |

| bytes_returned | No | Exact bytes the excerpt covers (cut at a line or character boundary). |
| replacement_chars | No | U+FFFD characters in the excerpt (invalid UTF-8 or a mid-character offset). |
Search Zenodo's open research repository — datasets, software releases, publications, and other deposits — by keyword query plus filters for resource type, community, funder, grant, creator ORCID, file type, license, access status, and publication date. Returns one summary per deposit (ids, DOIs, title, type, version, creators, license, access, file totals, usage counts) plus facet counts over the full match set, every filter applied. Query terms are OR-ed unless joined with AND, quoted phrases match exactly, and field syntax works on record fields (metadata.title:"…", metadata.subjects.subject:"…"). Only the latest version of each deposit is searched unless all_versions is true, and only the first 10,000 matches are reachable by paging. Resolve community, funder, and grant names to ids with zenodo_lookup_vocabulary first; open one deposit in full with zenodo_get_record.
| Name | Required | Description | Default |

| query | No | Keyword query. Terms are OR-ed unless joined with AND; "quoted phrases" match exactly; field syntax such as metadata.title:"…" or doi:"10.5281/zenodo.N" works. Escape a literal / as \/. A bare DOI or record URL is rejected; open it with zenodo_get_record instead. Omit to browse with filters only. | |
| funder | No | One funder: a ROR id (01cwqze88), a ROR URL, or a Crossref Funder DOI (10.13039/100000002). Resolve a funder name with zenodo_lookup_vocabulary (vocabulary: funders). | |

| creator_orcid | No | Creator ORCID iD, e.g. 0000-0002-1825-0097; an https://orcid.org/ prefix is stripped and a trailing x uppercased. | |
| resource_type | No | Resource type ids, OR-ed (a single string is accepted): dataset, software, publication, publication-article, image-photo, … Any case; a subtype may also be written in the <type>::<id> form zenodo_lookup_vocabulary shows as its search value (publication::publication-article). A top-level type includes its subtypes. Look ids up with zenodo_lookup_vocabulary (vocabulary: resource_types). | |
| published_from | No | Earliest publication date, YYYY, YYYY-MM, or YYYY-MM-DD; a partial date starts at its first day. |
