The platform includes global airline content via accreditation, loyalty content, and rich booking workflows (search, book, changes, cancellations), with client libraries (Node.js, Python, Ruby), a JavaScript CLI, and prebuilt components like seat selection and payments. Pricing is available per component with a combination of per-order fees, monthly charges, and variable commissions, plus enterprise options and bespoke pricing for scaled usage.
