API & integration

Plug the read into your stack.

A directional read only earns its keep if it reaches the people who reroute a sailing, send a client note, or reprice a cabin. attuneline ships the same signal three ways — pick what your operations already accept.

Three delivery modes

One reading, three surfaces. No feature you have to log into if you would rather not.

Mode 01

Email briefs

Every cycle, the full reading lands in the inbox of whoever plans the season. No dashboard, no seat to provision.

From €1.99 / quarter →
Mode 02

Report library

The current cycle plus two past editions, free to read and downloadable for your own client briefings and ops decks.

Open the library →
Mode 03

Machine-readable feed

The same signal as structured JSON — pushed or pulled, key-authed, ready to feed routing and alerting logic.

The planned API surface

What the feed looks like. This is the planned contract for the prototype — endpoints, shape and auth. Not callable yet; live service lands before launch.

Pre-launch status. Tiers and pricing above are the planned structure. The live API, key auth and request docs land before launch — this page is the agreed UI surface, not a working endpoint yet.

Start at the price of a coffee.

Read a real edition free, then add the machine-readable feed when it has paid for itself once.
