Do We Have It API

Book "do we have it" can be queried by either ISBN or ASIN. There are plans to also support title.

Either an ASIN or ISBN can be submitted for the isbn key. The API will detect whether the value is an ASIN or an ISBN.

When the API request if received by the IA server, the server is looking for different identifiers that may be related to the queried identifier, for example: related ISBNs or ASINs, related items that exist in IA’s collections, etc.

Based on the data that the IA has on these related items, it calculates an response status and responds with the following fields:

{
  status: "ok",
  response: 0,
  message: "we have this book",
  ia_identifiers: 
    {
      ia_identifier: "lorem00ipsum",
      score: 1
    },
  response_time: 0.1064
}

status

response/message

response time - The time it took for IA’s server to generate the response
score - 1 if the book is an exact match, 0.5 if it's a related match
