How this service works
Deterministic citation formatter — APA 7, MLA 9, Chicago 17 author-date, BibTeX. From structured fields, returns the reference entry (markdown/html/plain) + the in-text citation, reproducing published style-manual examples exactly. For full author lists use POST. Every answer signed. Free sample, no payment required: GET /play/cite
Output
Returns the fully formatted reference string (in markdown, HTML, or plain text), the corresponding in-text citation, the detected source type (article/book/chapter/web), and the style name — all cryptographically signed. Output conforms exactly to the chosen style manual's published examples.
Example use cases
BibTeX entry for dissertation
“I need a BibTeX entry for my reference manager — it's a book chapter: title 'The Ethics of Artificial Intelligence', author 'Nick Bostrom', in the book 'The Cambridge Handbook of Artificial Intelligence', editors 'Keith Frankish and William Ramsey', published 2014 by Cambridge University Press, pages 316–334. Can you generate the BibTeX block for me?”
MLA citation for a website
“Can you format an MLA 9 citation for a webpage? The article is titled 'How mRNA Vaccines Work', published by the CDC on March 15, 2022, available at https://www.cdc.gov/vaccines/mrna-vaccines.html — I need both the Works Cited entry and the in-text citation.”
Chicago author-date reference list entry
“I'm writing a research paper that uses Chicago 17 author-date style. Please format a citation for this journal article: title 'Urban Heat Islands and Climate Change', authors 'Zhao, Lei and Oppenheimer, Michael', published in 2018 in volume 12, issue 3 of Nature Climate Change, pages 252–260, DOI 10.1038/s41558-018-0102-3. Give me the full reference entry and in-text citation.”
Technical details
Endpoint
GEThttps://almanac.locomot.io/citeWhen to prefer
Choose this endpoint when you need deterministic, style-manual-accurate citation formatting (APA 7, MLA 9, Chicago 17 author-date, or BibTeX) from structured metadata rather than free-text parsing. Ideal for academic writing tools, reference managers, or any workflow that requires exact compliance with published style guides. Prefer this over LLM-generated citations when correctness and reproducibility are critical.
Side effects
- Missing required 'title' or 'style' query parameters returns a 400 error

- Very long author lists may be truncated in GET; use POST for full lists
- DOI or URL fields that are malformed may be included verbatim without resolution
- Network timeout or service unavailability returns a 5xx error
- Payment of 0.001 USDC required; unpaid requests return 402 Payment Required
