API

POST a request:

To get e.g. BibTeX for a set of records you do a POST request to the endpoint

https://api.adsabs.harvard.edu/v1/export/bibtex

within the POST header payload is defined as

{"bibcode":["<bibcode1>","<bibcode2>", ...]}

For example to get the BibTeX for the record with bibcode 2015ApJS..219...21Z, you would do

curl -H "Authorization: Bearer <your API token>" -H "Content-Type: application/json" -X POST -d '{"bibcode":["2015ApJS..219...21Z"]}' https://api.adsabs.harvard.edu/v1/export/bibtex

and the API then responds in JSON with

{u'msg': u'Retrieved 1 abstracts, starting with number 1.  Total number selected: 1.', u'export': u'@ARTICLE{2015ApJS..219...21Z,\n   author = {{Zhang}, M. and {Fang}, M. and {Wang}, H. and {Sun}, J. and \n\t{Wang}, M. and {Jiang}, Z. and {Anathipindika}, S.},\n    title = "{A Deep Near-infrared Survey toward the Aquila Molecular Cloud. I. Molecular Hydrogen Outflows}",\n  journal = {\\apjs},\narchivePrefix = "arXiv",\n   eprint = {1506.08372},\n primaryClass = "astro-ph.SR",\n keywords = {infrared: ISM, ISM: jets and outflows, shock waves, stars: formation, stars: winds, outflows},\n     year = 2015,\n    month = aug,\n   volume = 219,\n      eid = {21},\n    pages = {21},\n      doi = {10.1088/0067-0049/219/2/21},\n   adsurl = {http://adsabs.harvard.edu/abs/2015ApJS..219...21Z},\n  adsnote = {Provided by the SAO/NASA Astrophysics Data System}\n}\n\n'}

Note that there is an optional parameter sort for sorting the records from solr. The default sort option (if omitted) is by date desc, bibcode desc. For example

curl -H "Authorization: Bearer <your API token>" -H "Content-Type: application/json" -X POST -d '{"bibcode":["2015ApJS..219...21Z", "2018AAS...23221409A"], "sort":"bibcode desc"}' https://api.adsabs.harvard.edu/v1/export/bibtex

To return the records in the exact order of input bibcode list, set sort to no sort.

1. For the following endpoints output is in tagged format:

/bibtex BibTeX reference list
/bibtexabs BibTeX with abstracts
/ads Generic tagged abstracts
/endnote EndNote format
/procite ProCite format
/ris Refman format
/refworks RefWorks format
/medlars MEDLARS format

2. For the following endpoints output is in latex format:

/aastex AASTeX format
/icarus Icarus format
/mnras MNRAS format
/soph SoPh format

Note that for the endpoints /aastex there is an optional parameter journalformat which allows user to decide on the format of journal name. 1 indicates to use AASTeX macros if there are any (default), otherwise full journal name is exported. 2 means use journal abbreviations and 3 means use full journal name.

3. For the following endpoints output is in xml format:

/dcxml Dublin Core XML
/refxml XML references
/refabsxml XML with abstracts
/votable VOTables
/rss RSS
/jatsxml JATS Journal Publishing XML

Note that for endpoints /bibtex and /bibtexabs optional parameters maxauthor, authorcutoff, keyformat and journalformat can be passed in.

maxauthor is maxinum number of authors displayed. The default values for maxauthor for /bibtex and /bibtexabs respectivley are 10 and 0, where 0 means all.
authorcutoff is the threshold for truncating number of authors. If the number of authors is larger than authorcutoff, author list is truncated and maxauthor number of authors will be returned followed by et al.. If authorcutoff is not specified, the default of 200 is used.
keyformat allows user to customize bibtex key and could contain some combination of authors' last name(s), publication year, journal, and bibcode. User is now able to pick the key generation algorithm by specifying a custom format for it. To provide a specific example, this is our default format for 2019AAS...23338108A:
```
  @INPROCEEDINGS{2019AAS...23338108A,
     author = {{Accomazzi}, Alberto and {Kurtz}, Michael J. and {Henneken}, Edwin and
  ...
```
In addition keyformat accepts specifier %zm to enumerate keys (one character alphabet) should duplicate keys get created. Note that if enumeration specifier is not included, even if duplicate key are found, service does not enumerate the keys.

Now user can define one of the following:
```
  Accomazzi:2019              -- %1H:%Y
  Accomazzi:2019:AAS          -- %1H:%Y:%q
  Accomazzi2019               -- %1H%Y
  Accomazzi2019AAS            -- %1H%Y%q
  AccomazziKurtz2019          -- %2H%Y
```
journalformat allows user to decide on the format of journal name. 1 indicates to use AASTeX macros if there are any (default), otherwise full journal name is exported. 2 means use journal abbreviations and 3 means use full journal name.

Note that for endpoint /rss an optional parameter link can be passed in. link is the query url that generated the bibcodes.

For example querying ADS Bumblebee for

author:"accomazzi" and year:2018

at the end of March 2018, returns the following 4 bibcodes, and generates the url as specified below:

{"bibcode":["2018arXiv180303598K","2018arXiv180101021FB","2018AAS...23136217A","2018AAS...23130709A"], "link":"https://ui.adsabs.harvard.edu/#search/q=author%3A%22accomazzi%22%20and%20year%3A2018&sort=date%20desc%2C%20bibcode%20desc"}

which can be passed as payload to /rss endpoint.

4. Using endpoint /csl allows various styles and output formats to be defined in payload as follows:

{"bibcode":["1980ApJS...44..137K","1980ApJS...44..489B"], "style":"", "format":"", sort:"date desc, bibcode, desc"}

where style can be: aastex, icarus, mnras, soph, aspc, apsj, aasj or ieee, and format can be: 1, 2 or 3, for output formats Unicode, HTML or LaTeX respectively. There is an optional parameter journalformat applicable to the three formats: aastex, aspc, and aasj, which allows user to decide on the format of journal name, with values 1, 2, and 3 respectively to indicate uses AASTeX macros (default), use journal abbreviations, or use full journal name.

5. Using endpoint /ieee output is in ieee format, unicode encoded

note that IEEE format can be both accessed through its own endpoint /ieee, and /csl with style set to ieee.

6. For endpoint /custom define payload as:

{"bibcode":["1980ApJS...44..137K","1980ApJS...44..489B"], "format":"%ZEncoding:latex%ZLinelength:0\bibitem[%4m(%Y)]{%R} %5.3l\ %Y, %j, %V, %p.\n"}

GET a request:

GET endpoints are similar to the POSTS endpoints. The curl command has the following syntax:

curl -H "Authorization: Bearer <your API token>" <endpoint>/<bibcode>`

To Convert a Classic Custom Format to the Current Custom Format:

curl -H "Authorization: Bearer <your API token>" -H "Content-Type: application/json" -X POST -d <payload> <endpoint>

where <endpoint> is /convert and <payload> is formatted as: {"format":}

For example:

curl -H "Authorization: Bearer <your API token>" -H "Content-Type: application/json" -X POST -d '{"format":"\\\\bibitem[%\\2m%(y)]\\{%za1%y} %\\8l %\\Y,%\\j,%\\V,%\\p"}' https://api.adsabs.harvard.edu/v1/export/convert
