- [OpenAPI spec](https://firecrawl.dev/alexandria/agents/providers/pubmed-ncbi-nlm-nih-gov/openapi.json)

## Capabilities

- [Article](https://firecrawl.dev/alexandria/agents/providers/pubmed-ncbi-nlm-nih-gov/publications/article): One PubMed record in full from NCBI E-utilities efetch XML (ep-19): title, abstract (plain text plus labelled sections for structured abstracts), authors with affiliations and ORCID, journal and issue, publication date and history, language, publication types, MeSH headings with qualifiers and major-topic flags, keywords, chemicals, grants, conflict-of-interest statement, identifiers (PMID, DOI, PMCID, PII) and the reference list with PMIDs where PubMed has them. NCBI Bookshelf records (GeneReviews, StatPearls, LiverTox, LactMed chapters and whole books) return the same shape with the journal fields null plus a `book` object (book title, NBK accession, publisher, editors). Accepts a PMID or a `pubmed.ncbi.nlm.nih.gov/{pmid}/` URL. An unknown PMID is `not_found`.
- [Full text](https://firecrawl.dev/alexandria/agents/providers/pubmed-ncbi-nlm-nih-gov/publications/full_text): Full text of a PubMed Central article from the NCBI BioC RESTful service (ep-31, `pmcoa.cgi`), which serves the PMC Open Access subset: title, license, article ids, authors, year and every passage (abstract, section headings, paragraphs, table and figure captions) with its section type, in reading order. `availability` is `full_text` when body passages are present, `abstract_only` when the OA record has only front matter (typical for preprints), and `not_in_open_access_subset` when PMC knows the article but does not license its text for the service (then `sections` is empty and ids come from the PMC ID Converter, ep-25). Accepts a PMCID or a `pmc.ncbi.nlm.nih.gov/articles/PMC.../` URL; an unknown PMCID is `not_found`. `max_chars` truncates the concatenated text.
- [Related](https://firecrawl.dev/alexandria/agents/providers/pubmed-ncbi-nlm-nih-gov/publications/related): Articles linked to one PMID through NCBI E-utilities elink (ep-21): `similar` (PubMed's computed similar-articles list, `pubmed_pubmed`, the article itself removed), `cited_in` (PubMed articles citing it, `pubmed_pubmed_citedin`) or `references` (its references that are in PubMed, `pubmed_pubmed_refs`). Returns every linked PMID count, the first `limit` ids and, unless disabled, their document summaries via esummary (ep-18). An unknown PMID is `not_found`; a known article with no links of that kind is a valid empty list.
- [Resolve ids](https://firecrawl.dev/alexandria/agents/providers/pubmed-ncbi-nlm-nih-gov/publications/resolve_ids): Convert between PMIDs, PMCIDs, DOIs and NIHMS manuscript ids with the PMC ID Converter API (ep-25), up to 200 ids per call of one type. `idtype` is inferred when omitted (`PMC...` = pmcid, `10.x/...` = doi, digits = pmid). Each record carries every id PMC knows plus the PubMed and PMC page URLs; ids PMC does not know appear with `status: error` and in `unmatched`. When nothing resolves the result is `not_found`. Note the converter only knows articles that are in PMC: a valid PMID for an article without a PMC copy is reported as unmatched.
- [Search](https://firecrawl.dev/alexandria/agents/providers/pubmed-ncbi-nlm-nih-gov/publications/search): Search PubMed or PMC with the full PubMed query syntax (`crispr[Title] AND 2024[dp]`, MeSH terms, field tags) through NCBI E-utilities esearch (ep-17), then fetch document summaries for the page through esummary (ep-18): title, authors, journal, dates, volume/issue/pages, publication types and PMID/PMCID/DOI. Offset-paginated (`offset`, `next_offset`); `total_count` is the full hit count and `query_translation` shows how PubMed expanded the query. Empty results are a valid empty page.
- [Summaries](https://firecrawl.dev/alexandria/agents/providers/pubmed-ncbi-nlm-nih-gov/publications/summaries): Document summaries for up to 50 PMIDs (or PMCIDs with `db=pmc`) in one NCBI E-utilities esummary call (ep-18): title, authors, journal, publication and e-publication dates, volume/issue/pages, publication types, languages, PMID/PMCID/DOI, PMC cited-by count and record status. Ids PubMed does not know are listed in `missing`; when none resolve the result is `not_found`.

  "abstract": "In the past 20 years, sequencing technologies have led to easy access to genomic data from nonmodel organisms in all biological realms. Insect genetic manipulation, however, continues to be a challenge due to various factors, including technical and cost-related issues. Traditional techniques such as microinjection of gene-editing vectors into early stage embryos have been used for arthropod transgenesis and the discovery of Clustered regularly interspaced short palindromic repeats and CRISPR-associated protein (CRISPR-Cas) technologies allowed for targeted mutagenesis and the creation of knockouts or knock-ins in arthropods. Receptor-Mediated Ovary Transduction of Cargo (ReMOT Control) acts as an alternative to embryonic microinjections, which require expensive equipment and extensive hands-on training. ReMOT Control's main advantage is its ease of use coupled with the ability to hypothetically target any vitellogenic species, as injections are administered to the egg-laying adult rather than embryos. After its initial application in the mosquito Aedes aegypti, ReMOT Control has successfully produced mutants not only for mosquitoes but for multiple arthropod species from diverse orders, such as ticks, mites, wasps, beetles, and true bugs, and is being extended to crustaceans, demonstrating the versatility of the technique. In this review, we discuss the current state of ReMOT Control from its proof-of-concept to the advances and challenges in the application across species after 5 years since its development, including novel extensions of the technique such as direct parental (DIPA)-CRISPR.",

### Full text

- Capability: `publications/full_text`
- Description: Full text of a PubMed Central article from the NCBI BioC RESTful service (ep-31, `pmcoa.cgi`), which serves the PMC Open Access subset: title, license, article ids, authors, year and every passage (abstract, section headings, paragraphs, table and figure captions) with its section type, in reading order. `availability` is `full_text` when body passages are present, `abstract_only` when the OA record has only front matter (typical for preprints), and `not_in_open_access_subset` when PMC knows the article but does not license its text for the service (then `sections` is empty and ids come from the PMC ID Converter, ep-25). Accepts a PMCID or a `pmc.ncbi.nlm.nih.gov/articles/PMC.../` URL; an unknown PMCID is `not_found`. `max_chars` truncates the concatenated text.
- Instructions: Read the body of an open-access paper once you have its PMCID (from `search` with `db=pmc`, `summaries`, `article` identifiers or `resolve_ids`). Publisher-restricted articles only expose the abstract through `article`.
- Cost: 5 credits per call
- Capability file: [Full text](https://firecrawl.dev/alexandria/agents/providers/pubmed-ncbi-nlm-nih-gov/publications/full_text)

Accepted options:
- `max_chars` (number): Stop adding passages once the returned text reaches this many characters (`truncated` becomes true). Example: `200`
- `pmcid` (string): PMC identifier with or without the `PMC` prefix (e.g. `PMC3531190`). Pattern: ^(PMC|pmc)?[0-9]{1,9}$. Example: `<pmcid>`
- `url` (string): PMC article URL, e.g. `https://pmc.ncbi.nlm.nih.gov/articles/PMC3531190/`. Exactly one of `pmcid` and `url`. Example: `https://pmc.ncbi.nlm.nih.gov/articles/PMC3531190/`

Most submissions are made using the web-based BankIt or standalone Sequin programs, and GenBank staff assigns accession numbers upon data receipt. Daily data exchange with the European Nucleotide Archive (ENA) and the DNA Data Bank of Japan (DDBJ) ensures worldwide coverage. GenBank is accessible through the NCBI Entrez retrieval system, which integrates data from the major DNA and protein sequence databases along with taxonomy, genome, mapping, protein structure and domain information, and the biomedical journal literature via PubMed. BLAST provides sequence similarity searches of GenBank and other sequence databases. Complete bimonthly releases and daily updates of the GenBank database are available by FTP.

### Related

- Capability: `publications/related`
- Description: Articles linked to one PMID through NCBI E-utilities elink (ep-21): `similar` (PubMed's computed similar-articles list, `pubmed_pubmed`, the article itself removed), `cited_in` (PubMed articles citing it, `pubmed_pubmed_citedin`) or `references` (its references that are in PubMed, `pubmed_pubmed_refs`). Returns every linked PMID count, the first `limit` ids and, unless disabled, their document summaries via esummary (ep-18). An unknown PMID is `not_found`; a known article with no links of that kind is a valid empty list.
- Instructions: Expand from one paper to its neighbourhood: reviews on the same topic (`similar`), later work building on it (`cited_in`) or what it built on (`references`).
- Cost: 5 credits per call
- Capability file: [Related](https://firecrawl.dev/alexandria/agents/providers/pubmed-ncbi-nlm-nih-gov/publications/related)

Accepted options:
- `include_summaries` (boolean): When false, return ids only (one upstream request). Example: `false`
- `kind` (string): kind Example: `similar`
- `limit` (number): How many linked ids to return summaries for (and to list in `ids`). Example: `20`
- `pmid` (string, required): PubMed identifier, digits only (e.g. `37742320`). Pattern: ^[0-9]{1,9}$. Example: `37742320`

### Resolve ids

- Capability: `publications/resolve_ids`
- Description: Convert between PMIDs, PMCIDs, DOIs and NIHMS manuscript ids with the PMC ID Converter API (ep-25), up to 200 ids per call of one type. `idtype` is inferred when omitted (`PMC...` = pmcid, `10.x/...` = doi, digits = pmid). Each record carries every id PMC knows plus the PubMed and PMC page URLs; ids PMC does not know appear with `status: error` and in `unmatched`. When nothing resolves the result is `not_found`. Note the converter only knows articles that are in PMC: a valid PMID for an article without a PMC copy is reported as unmatched.
- Instructions: Turn a DOI into a PMID before calling `article`, or a PMID into a PMCID before calling `full_text`.
- Cost: 5 credits per call
- Capability file: [Resolve ids](https://firecrawl.dev/alexandria/agents/providers/pubmed-ncbi-nlm-nih-gov/publications/resolve_ids)

Accepted options:
- `ids` (string[], required): Identifiers of one type: PMIDs (`37742320`), PMCIDs (`PMC10755176`), DOIs (`10.1093/icb/icad123`) or manuscript ids (`NIHMS...`). Example: `["37742320"]`
- `idtype` (string): Type of every id in `ids`; inferred from their form when omitted. Example: `pmid`

Response schema example:
```json

### Search

- Capability: `publications/search`
- Description: Search PubMed or PMC with the full PubMed query syntax (`crispr[Title] AND 2024[dp]`, MeSH terms, field tags) through NCBI E-utilities esearch (ep-17), then fetch document summaries for the page through esummary (ep-18): title, authors, journal, dates, volume/issue/pages, publication types and PMID/PMCID/DOI. Offset-paginated (`offset`, `next_offset`); `total_count` is the full hit count and `query_translation` shows how PubMed expanded the query. Empty results are a valid empty page.
- Instructions: Start here to find PMIDs (or PMCIDs with `db=pmc`) for a topic, author or journal; then call `article` for the abstract and MeSH terms, `related` for similar/citing articles or `full_text` for open-access PMC text.
- Cost: 5 credits per call
- Capability file: [Search](https://firecrawl.dev/alexandria/agents/providers/pubmed-ncbi-nlm-nih-gov/publications/search)

Accepted options:
- `db` (string): Entrez database: `pubmed` (citations and abstracts) or `pmc` (PubMed Central full-text articles). Example: `pubmed`
- `include_summaries` (boolean): When false, skip the esummary call and return ids only (one upstream request instead of two). Example: `false`
- `limit` (number): Results per page (esearch retmax). Example: `20`
- `max_date` (string): Latest publication date, same forms as `min_date`. Requires `min_date`. Pattern: ^[0-9]{4}(/[0-9]{2}(/[0-9]{2})?)?$. Example: `min_date`
- `min_date` (string): Earliest publication date, `YYYY`, `YYYY/MM` or `YYYY/MM/DD` (esearch mindate with datetype=pdat). Requires `max_date`. Pattern: ^[0-9]{4}(/[0-9]{2}(/[0-9]{2})?)?$. Example: `<min_date>`
- `offset` (number): Zero-based index of the first result (esearch retstart). E-utilities cap offset + limit at 10,000. Example: `0`
- `query` (string, required): PubMed query; free text or field-tagged syntax exactly as accepted by the PubMed search box. Example: `<query>`
- `sort` (string): `relevance` (PubMed best match) or `pub_date` (newest first). Example: `relevance`

### Summaries

- Capability: `publications/summaries`
- Description: Document summaries for up to 50 PMIDs (or PMCIDs with `db=pmc`) in one NCBI E-utilities esummary call (ep-18): title, authors, journal, publication and e-publication dates, volume/issue/pages, publication types, languages, PMID/PMCID/DOI, PMC cited-by count and record status. Ids PubMed does not know are listed in `missing`; when none resolve the result is `not_found`.
- Instructions: Batch lookup of bibliographic metadata for known ids (from `search`, `related`, a reference list or a DOI resolved with `resolve_ids`). Use `article` when you need the abstract or MeSH headings.
- Cost: 5 credits per call
- Capability file: [Summaries](https://firecrawl.dev/alexandria/agents/providers/pubmed-ncbi-nlm-nih-gov/publications/summaries)

Accepted options:
- `db` (string): Entrez database: `pubmed` (citations and abstracts) or `pmc` (PubMed Central full-text articles). Example: `pubmed`
- `ids` (string[], required): 1 to 50 identifiers. Example: `[]`
