Common use cases
Quickstart
Every Zephiel API uses the same base URL, the same key header, and the same error envelope.

Yuki Tanaka
Backend Engineer
Good coverage for marine
We checked Marine & Agriculture Weather against our own marine reference data before committing. Coverage was better than the incumbent we were paying four times as much for.
Grace Mwangi
Head of Product
Documentation matched reality
Every sample in the Marine & Agriculture Weather docs ran unmodified. That sounds like a low bar until you have integrated something where it is not.
Mei Chen
Integration Engineer
Now handles irrigation scheduling too
We adopted Marine & Agriculture Weather for fishing and shipping operations and ended up using it for irrigation scheduling as well. Same key, no new contract, no second integration.
Peter Osei
DevOps Lead
Support answered properly
Asked Zephiel Labs about an edge case in Marine & Agriculture Weather and got an explanation from someone who had clearly read the code, not a link to the FAQ.
Rachel Kimani
Head of Integrations
Quietly reliable
Marine & Agriculture Weather has not surprised us once in eight months of production traffic. That is the highest compliment I can pay a dependency.
Chidi Nwosu
Head of Engineering
One key made the difference
Adding Marine & Agriculture Weather took ten minutes because the credential already existed. The vendor onboarding we skipped would have taken longer than the integration.
James O'Connor
Technical Director
Solved Fishing and shipping operations for us
We brought Marine & Agriculture Weather in for Fishing and shipping operations and it has not needed revisiting since. The response shape matched the documentation on the first call, which is rarer than it should be.
Aisha Suleiman
Digital Lead
Fast enough to sit in the request path
95ms median is quick enough that we call Marine & Agriculture Weather synchronously rather than queueing it. That removed a whole background worker from our architecture.
