Where 7807 fits

7807 connects to 2 worlds: mathematics, technology.

Before it, every API invented its own error format, so a client had to learn a new one for each service it called.

7807is also used in ways where ordinary arithmetic doesn't apply — each listed below with what genuinely does and doesn't follow from it.

Mathematical number
A genuine quantity — its mathematical properties (prime, square, factors, and so on) are real facts about it.
A genuine quantity that ordinary arithmetic applies to — it can be prime, even, a perfect square, added to another number meaningfully, and so on.
Code
Also used as a code — HTTP status codes.
An assigned identifier from a fixed registry or standard — its digits don't represent an amount, and arithmetic on it is meaningless (HTTP status 404 + 1 is not a 'better' status; it's a different, unrelated code).

Documented appearance

Problem Details gives a machine-readable body to accompany the status code, which the code alone cannot convey.

RFC 7807 defines the application/problem+json media type with type, title, status, detail and instance members, giving APIs a shared structure for reporting failure.
