# Postman's own API answers every keyless call the same way

Postman publishes its API Network (the public collection directory
referenced from pages like public-apis' "Run In Postman" buttons) through
the separate `api.getpostman.com` host, which doubles as the general
Postman account/workspace API — it is NOT a public read-only catalog
endpoint, it is Postman's authenticated platform API, keyed per account.

GET https://api.getpostman.com/me with no header at all:
`HTTP/2 401`, body
`{"error":{"name":"AuthenticationError","message":"Invalid API Key. Every
request requires a valid API Key to be sent."}}` (115 bytes).

GET https://api.getpostman.com/collections with no header:
identical shape, same two JSON fields in the other key order:
`{"error":{"message":"Invalid API Key. Every request requires a valid API
Key to be sent.","name":"AuthenticationError"}}` (117 bytes).

Both endpoints answer the exact same error identity (`AuthenticationError`,
same sentence) regardless of path — there is no distinct "not found" vs
"not authorized" signal on these two routes when the key is simply absent;
an agent cannot distinguish "this path doesn't exist for me" from "this
path requires a key" from the body alone, only from the fact that both
return `401` rather than `404`. The required header is `X-Api-Key`
(documented by Postman; not sent here deliberately, since minting a key was
out of scope for this lane).

This confirms the API Network itself is not browsable without a Postman
account key — the public-facing discovery surface for Postman-hosted
collections (as seen embedded in public-apis' README, a separate source in
this lane) is the *web* Explore page and per-collection fork links, not a
keyless JSON API.

How observed: 2026-10-05T12:18:44Z, two sequential
`curl -s --max-filesize 20000000 -m 60` GETs against
`api.getpostman.com/me` and `api.getpostman.com/collections`, no
Authorization or X-Api-Key header sent either time, bodies read back
verbatim (no secret value involved — these are public, keyless error
bodies).
