find_by_id
Find a paper by any external identifier: OpenArx ID (oarx-…), DOI, arXiv ID, Semantic Scholar Corpus ID, DBLP ID. arXiv-style DOIs (10.48550/arXiv.) are auto-resolved to the underlying arxiv_id even if the doi field is not stored. An identifier resolves to one specific version of a document, not to a mutable current state, so a reference cannot silently come to mean different text.
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| doi | No | DOI (e.g. 10.1234/...). arXiv-style DOIs (10.48550/arXiv.1706.03762) are auto-resolved to arXiv lookup; non-arXiv DOIs require the doi to be present in externalIds. | |
| s2_id | No | Semantic Scholar Corpus ID | |
| run_id | No | Optional. The active methodist run_id (as returned by the methodist diagnose / get_current_dose door). Pass it whenever you call this tool while working inside a run, so the call is attributed to that run for the §8 usage crosscheck — attribution is run-anchored, so it stays correct even if your access token refreshes mid-run. Must be YOUR run: a run_id owned by a different principal, or a non-existent run_id, is rejected. | |
| dblp_id | No | DBLP key like "conf/iclr/HuSWALWWC22" or "journals/corr/abs-1706-03762" | |
| oarx_id | No | OpenArx ID (e.g. oarx-f629d9b6a1c2e3d4). Legacy 8-hex ids (oarx-f629d9b6) are also accepted and resolved by prefix. | |
| arxiv_id | No | arXiv ID (e.g. 1706.03762) |
