resolve-identifier

# resolveIdentifier Resolves a single bibliographic identifier to canonical CSL JSON metadata via the Scholar Sidekick resolver chain (Crossref → PubMed → DataCite → arXiv → ADS → ISBN → WHO IRIS, with deterministic fallback order). ## When to use - The user provides a single DOI (including a shortDOI alias like `10/aabbe`), PMID, PMCID, ISBN, ISSN, arXiv ID, ADS bibcode, or WHO IRIS URL and wants the underlying metadata. - An agent needs structured fields (author list, title, container, year, identifiers) before formatting or exporting. ## Inputs - `identifier` (string, required) — DOI like `10.1038/nphys1170`, PMID like `34812345`, ISBN, etc. Detection is automatic. A shortDOI alias (`10/aabbe`, from shortdoi.org) is accepted anywhere a DOI is, and expanded to the full DOI before resolving. ## Outputs CSL JSON with at least `title`, `author[]`, `issued`, `container-title`, `DOI`/`PMID`/`PMCID`/`URL` (depending on source). Errors return `{ ok: false, code, error }`. ## Underlying surfaces - **REST**: `POST /api/format` with `text: "<identifier>"` and `output: "json"` returns the resolved item alongside the formatted string. - **MCP tool**: `resolveIdentifier` in [`scholar-sidekick-mcp`](https://github.com/mlava/scholar-sidekick-mcp). ## Example ```bash curl -sS -X POST "https://scholar-sidekick.com/api/format" \ -H "Content-Type: application/json" \ -d '{"text":"10.1038/nphys1170","style":"vancouver","output":"text"}' ``` ## See also - `formatCitation` for rendering, `verifyCitation` for fabrication detection. - [`/llms.txt`](https://scholar-sidekick.com/llms.txt) for the full service description.
