+#!/usr/bin/env python3
+"""
+Probe every shape of ESPN request this repo makes, and say what is actually wrong.
+
+ESPN has no public API. Every endpoint the scoreboards use is undocumented and
+can change without notice, so "the ESPN plugins went blank" is a report we get
+periodically and can rarely act on: it arrives as a symptom, and the interesting
+question — *which* part broke — needs a machine that can reach ESPN to answer.
+This script is that answer. Run it from a host with normal internet access (a
+Pi running LEDMatrix, a laptop) and it reports, per endpoint, whether ESPN still
+serves what the plugins expect.
+
+The important trick is the second axis: each endpoint is tried under several
+``User-Agent`` values, because anti-bot filtering is the most common way an
+undocumented API "changes" and it discriminates on exactly that header.
+
+Do not assume which side of that filter is the safe one. This script originally
+tested for the familiar shape — a browser agent works, a script agent is
+refused — and reported "healthy" all the way through the 2026-08-04 outage,
+where ESPN had inverted it:
+
+* a browser string is refused unconditionally (no other header rescues it),
+* a bare custom token like ``LEDMatrix/1.0`` is refused when the request also
+  sends no ``Accept`` header,
+* honest client tokens (``python-requests``, ``curl``, ``Python-urllib``) and a
+  token carrying a project URL are accepted.
+
+So the profiles below are split into what the plugins actually send (``shipped``)
+and controls kept only to characterise the filter, and the verdict is
+direction-agnostic — it names which agents were accepted and which refused
+rather than assuming. The diagnosis:
+
+* every profile fails  -> ESPN moved or withdrew the endpoint; the URL needs work.
+* some accepted, some refused -> ESPN is filtering on User-Agent. It only breaks
+  the plugins if a *shipped* profile is on the refused side; the fix is then a
+  header change, not a URL change.
+* everything passes -> ESPN is fine; look at the plugin, the cache, or the
+  network in front of it.
+
+Usage::
+
+    python scripts/check_espn_api.py              # probe, non-zero exit if broken
+    python scripts/check_espn_api.py --verbose    # show every profile's result
+    python scripts/check_espn_api.py --json       # machine-readable report
