Resolve Identifier
resolveIdentifierResolve DOI, PMID, PMCID, ISBN, arXiv, ISSN, NASA ADS, or WHO IRIS identifiers into structured CSL JSON metadata for raw bibliographic data.
Instructions
Resolve scholarly identifiers to structured CSL JSON metadata (title, authors, journal, year, identifiers). Use when the user wants raw bibliographic data to inspect, transform, or feed into another tool — not a formatted citation. Common single-shot conversions: PMID → PMCID, arXiv → DOI, ISBN → CSL JSON, WHO IRIS URL → structured metadata. Accepts DOI, PMID, PMCID, ISBN, arXiv ID, ISSN, NASA ADS bibcode, or WHO IRIS URL, with or without prefixes (PMID:, arXiv:, ISBN hyphens, https://doi.org/...). Pass a single identifier or a comma/newline-separated batch — one round trip per call. Returns: a JSON array of CSL items, each with id, type, title, author[], issued.date-parts, container-title, DOI/PMID/PMCID/ISBN/ISSN/URL when available. Use formatCitation instead when the user wants a finished citation string in a specific style; use exportCitation when they want a downloadable bibliography file. Read-only and idempotent — safe to retry. Works anonymously against the public Scholar Sidekick API (rate-limited free tier); set SCHOLAR_API_KEY (a free ssk_ key from https://scholar-sidekick.com/account) for higher limits, or RAPIDAPI_KEY for paid RapidAPI tiers. Rate limits follow your tier; the underlying REST API caches repeated identical requests and surfaces cache state in the x-scholar-cache response header.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes | One or more scholarly identifiers to process — DOI (with or without https://doi.org/), PMID (with or without 'PMID:' prefix), PMCID (e.g. PMC7793608), ISBN (10 or 13 digit, hyphens tolerated), arXiv ID (with or without 'arXiv:' prefix; old-style hep-ph/0501023 also accepted), ISSN, NASA ADS bibcode (19 chars), or WHO IRIS URL. Pass identifiers verbatim — do not strip prefixes. Multiple identifiers may be separated by newlines or commas; mixed types in one batch are supported and resolved in a single round trip. |
