Everbread's Haystack provides online travel agencies as well as travel meta-search websites with a highly customizable airfare shopping engine and multi-source data solution tool.
The Haystack miniAPI offers a streamlined method for utilizing Haystack. You can build widgets, extensions, websites and other tools to display content from Haystack's data feeds which include low cost and traditional airline carriers. You can also receive up to 300 free API calls per day. The miniAPI does not allow you to book results.
The miniAPI utilizes a JSON-RPC protocol and returns are formatted in JSON.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
