Space weather now from NOAA SWPC: geomagnetic Kp index (recent hours and max), storm level (G0-G5), latest solar X-ray flares, solar wind speed and active alerts. Affects satellites, GPS and power grids.

Test a regular expression against a text: every match with position, groups and named groups, plus the result of a substitution if you pass a replacement. Flags i, m, s, x. Time-limited, safe against catastrophic backtracking.

Takes a video and an audio file (for example a dubbed track from /v1/dub, a voice-over or music) and returns the video with the new sound: mode replace drops the original audio, mode mix keeps it at original_volume underneath. The new audio is trimmed to the video length or padded with silence, optionally delayed by offset_seconds. The picture is copied, not re-encoded. Output MP4 with AAC inline as base64, max 24 MB. Runs locally with ffmpeg. Fixed price per call.

Takes a video of up to 30 minutes and finds, in one pass, segments where the picture is black (blackdetect), where it freezes (freezedetect) and where the sound drops out (silencedetect), each with start, end and duration, using minimum lengths and thresholds you can set. A summary says whether the file passes with no finding longer than the limits. Leading and trailing black is reported separately because it is often intended. Runs locally with ffmpeg; nothing leaves this machine.

Takes a video (up to 24 MB) and returns one JPEG with columns × rows frames taken at evenly spaced times across the running time, each tile labelled with its timestamp, and the list of those times. Tile width, grid size and JPEG quality are selectable. Useful for a quick visual overview, for choosing a thumbnail, or as a single image to hand to a vision model instead of a whole video. Runs locally with ffmpeg; nothing leaves this machine. Fixed price per call.

Takes a video of up to 10 minutes and 24 MB and returns it as MP4 with H.264 and AAC and fast-start for web playback, or as WebM with VP9 and Opus, scaled down to max_width if larger (aspect ratio kept), at high, medium or low quality, optionally with the audio removed. Input and output facts — container, codec, resolution, frame rate, duration and size — are measured and returned with the size ratio. Output inline as base64, max 24 MB. Runs locally with ffmpeg; nothing leaves this machine.

Takes a video by URL or inline base64 and returns what an agent needs to work with it without watching it. The soundtrack is transcribed with paragraphs and timestamps; scene changes are detected with ffmpeg; chapters are cut at paragraph starts, preferring those within three seconds of a visual cut, at least min_chapter_seconds apart and at most 20.

Takes a video (up to 24 MB) and returns the part from start_seconds, up to 15 seconds long, as an animated GIF built with a palette computed for exactly this clip (much cleaner gradients than the default palette), or as animated WebP, which is smaller and true-colour but not supported everywhere. Width, frame rate and looping are selectable. Output inline as base64, max 12 MB; if the GIF would be larger, lower width or frame rate is suggested. Runs locally with ffmpeg. Fixed price per call.

Takes a video of up to 15 minutes, measures the integrated loudness, true peak and loudness range of its soundtrack, and normalises it to the chosen standard with two-pass linear loudnorm, so the dynamics are kept and the target is met closely. The picture is copied without re-encoding. Loudness is measured again on the result and both measurements are returned. Output MP4 with AAC audio inline as base64, max 24 MB. Runs locally with ffmpeg. Billing per started video minute.
