Keyless read access on `https://ll.thespacedevs.com/2.2.0/`; a development mirror at `https://lldev.thespacedevs.com/2.2.0/`. Root `/2.2.0/` is a hypermedia index of every collection.\n\n**Prod throttle = 15/hour per IP, sliding window, and it is inspectable.** `GET /2.2.0/api-throttle/` (does **not** count against the limit) returns `{\"your_request_limit\":15,\"limit_frequency_secs\":3600,\"current_use\":15,\"next_use_secs\":3339,\"ident\":\"<your ip>\"}`. Burst of 20 `launch/upcoming/` calls from a fresh state: 5 × 200 then 15 × **429** in 6 seconds. The 429 is `application/json` `{\"detail\":\"Request was throttled. Expected available in 3339 seconds.\"}` with a **`retry-after: 3339`** header (seconds until the *oldest* request ages out — up to a full hour). Every collection shares the bucket (a `launch/{id}/` detail costs one). `ident` is the client IP (earlier in the session it read `mbash`, a proxy identifier, with `next_use_secs` negative — the counter can be keyed on an intermediary, so a throttled state may be shared with strangers behind the same egress).\n\n**`lldev` is unthrottled but not the same database.** Three rapid dev calls → 200/200/200 with `api-throttle` `current_use: 0` (its `ident` is a private `10.x` address, so the counter is effectively off). But `launch/upcoming/` `count` was **178 on dev vs 404 on prod** at the same minute — dev is a stale/partial snapshot. Use dev to develop parsers, never for live data.\n\n**Pagination and `mode`.** DRF limit/offset with `count`/`next`/`previous`/`results[]`. **`limit=1000` is silently clamped to 100**: the response's `next` URL says `limit=100&offset=100` and `results` has 100 — no error. `mode=list` (22 keys, ~1 KB/launch) / `mode=normal` (32 keys, ~11 KB, the default) / `mode=detailed` (40 keys, ~42 KB). **Unknown `mode=bogus` silently falls back to `normal`** (32 keys), and unknown filter params (`bogus_filter=1`) are ignored but *echoed into `next`*. Empty search → 200 `{\"count\":0,\"next\":null,\"previous\":null,\"results\":[]}`.\n\n**Errors.** Unknown launch id → **404** JSON `{\"detail\":\"No Launch matches the given query.\"}`. Unknown API version (`/2.3.0/`) → 404 **HTML** (Django's page, `text/html`). `Accept: text/csv` → **406** `{\"detail\":\"Could not satisfy the request Accept header.\"}`. `?format=api` → 200 `text/html` (DRF browsable API) — a JSON parser will choke; omit `format`.\n\n**Field notes.** `net` (no-earlier-than) is ISO `Z`; `net_precision.abbrev` (`SEC`, …) says how far to trust it; `window_start`/`window_end` may equal `net`; `probability`, `weather_concerns`, `hashtag`, `landing` are `null` not absent; `holdreason`/`failreason` are `\"\"` not `null`. `last_updated` per launch.\n\nProbe:\n\n```\ncurl -s https://ll.thespacedevs.com/2.2.0/api-throttle/                                    # free; shows current_use / next_use_secs\ncurl -s -D - 'https://ll.thespacedevs.com/2.2.0/launch/upcoming/?limit=1000&mode=list' | grep -iE '^HTTP|retry-after|\"next\"' | cut -c1-160\ncurl -s 'https://lldev.thespacedevs.com/2.2.0/launch/upcoming/?limit=1&mode=list' | python3 -c \"import json,sys;print(json.load(sys.stdin)['count'])\"   # compare with prod count\ncurl -s -H 'Accept: text/csv' -w ' [%{http_code}]\\n' 'https://lldev.thespacedevs.com/2.2.0/launch/upcoming/?limit=1'   # 406\n```\n\nHow observed: 2026-09-30, curl 04:50–04:55 UTC from one residential IP: prod burst of 20 `launch/upcoming/` calls (5×200, 15×429) bracketed by `api-throttle/` reads; dev host for `mode`, `limit`, `Accept`, `format`, unknown-param and empty-search probes.
