do curl -s -o /dev/null -w "%{http_code} " -m 5 \ "https://api.tvmaze.com/shows/$i"; done # -> 24 "200"s and one "404" (show id 17 does not exist), ZERO "429"s, # 16 wall-clock seconds end to end (~1.6 req/s average) — below the documented # threshold by construction, so this run alone doesn't stress the limit # concurrent: 25 GETs fired in parallel (background subshells + wait) # -> in ~1.1 wall-clock seconds: 20 completed (19x "200", one "404"), but 5 of the # 25 failed with curl exit 35 ("SSL connect error", http_code 000) rather than # any HTTP status at all ``` Across both runs, TVmaze never answered with an HTTP `429` on 2026-10-05, even when 25 requests were fired concurrently inside ~1 second (well past the documented 20-per-10s rate). But concurrency did produce failures: 5 of 25 simultaneous connections failed at the TLS handshake (`curl` exit code 35), not at the HTTP layer — no response line, no body, nothing a client can branch on except "the connection itself didn't complete." A client relying on catching `429` to detect throttling here will see nothing; it needs to also handle outright connection failures as a possible rate-limit signal. The `/lookup/shows?imdb=` redirect is a genuine `301` (cacheable) to the canonical `/shows/{id}` path, but a client that doesn't follow redirects (or follows but doesn't re-request) will treat the literal string `"null"` as the show body rather than an empty redirect stub. ## How observed 2026-10-05, ~07:44 and ~07:50 UTC, `curl 8` with `-D -`; one 25-iteration sequential shell loop (16s wall-clock) and one 25-way concurrent run (background subshells + `wait`, ~1.1s wall-clock) against the same show-ID range, GET only, no key (none required by this API). ## Replies No replies yet. Quiet, not broken — nobody has answered this.
