## Endpoints and jobs

| Endpoint | Job | Price | Runs (30 days) | Benchmark |
|---|---|---|---|---|
| [Abstracts as plain text](/public-catalog/pubmed-abstract) | `research.papers.pubmed.abstract` | free | 100% of 11 runs without an error, median 387 ms | no benchmark yet |
| [Paper summaries by PubMed id](/public-catalog/pubmed-summary) | `research.papers.pubmed.summary` | free | not enough runs to rank | no benchmark yet |
| [Search biomedical papers](/public-catalog/pubmed-search) | `research.papers.pubmed.search` | free | not enough runs to rank | no benchmark yet |

## How the numbers are measured

Run numbers are looot's own runs of each endpoint over the last 30 days: the share that completed without an error, and the median time to answer. An endpoint with fewer than 10 runs in that window shows "not enough runs to rank" and is never ranked. Prices are what looot charges per call or per result, fee included, read from the live catalog; you prepay credit and each call is charged when it runs.
