Tools it offers

57 tools, as the server itself reported during our check on Oct 31, 2026.

• art_schemaEvery key, range and word a print design may use. Call this first when designing a print. Costs no units.
• art_presetsThe canvas presets: shirt-front 4500x5400, shirt-pocket 1200x1200, sticker 2400x2400, poster 5400x7200, all at 300 DPI. Costs no units.
• art_materialsThe shipped material library: each id, a line on its look, and whether it is a metal. Any id here can fill a layer or be baked. Costs no units.
• art_starterA valid starting design for a canvas preset, ready to edit. Costs no units.
• art_checkChecks a design without rendering it: ok, or one sentence naming the first problem and where it is. Costs no units.
• art_renderRenders a design to a PNG with its DPI written in. Without width it renders the canvas at full print size (a shirt-front is 4500 x 5400). width renders a draft that many pixels wide. A render 1200 pixels wide or less cos
• art_swatchRenders one material (a shipped id, or a whole material document) as a lit square swatch PNG. size is 64 to 1024 (default 512); 512 or less costs 1 unit, larger costs 2.
• material_bakeBakes a material (a shipped id, or a whole material document) to its seven channels (albedo, normal, roughness, metallic, height, emissive, ambient occlusion) as PNGs at res pixels square: 64, 128, 256, 512 or 1024 (defa
• material_checkChecks a material document against the engine's strict reader: admissible, or the refusal. Costs no units.
• material_costWhat baking a material document costs at res pixels square (default 256): operations and bytes. Costs no units.
• material_applyApplies a batch of ops (set_material, add_node, remove_node, set_node_param, connect, disconnect, set_out, add_ramp_stop, remove_ramp_stop, set_ramp_stop, add_curve_point, remove_curve_point, set_curve_point, clear_nodes
• form_starterA blank form document for a generator kind (growth, rock, face, blades, canopy, masonry, lathe, sweep, truss, frond), named by id. Costs no units.
• form_checkChecks a form document against the sculptor's strict reader. Costs no units.
• form_applyApplies a batch of ops (set_form, set_generator, set_range, reset_range, clear_params) to a form document, whole or not at all. Costs 1 unit.
• form_buildBuilds a form (a shipped id such as scots-pine, oak or boulder, or a whole form document) at one variant and reports what the sculptor drew: the knob values for that variant and each level of detail's vertex and triangle
• character_listThe body kinds (person, dog, cat, rat, sheep), the levels of detail and each kind's gaits. Costs no units.
• character_generateGenerates a character from a seed. A person is one of the game's townspeople: sex, age, complexion, hair, build and working clothes are drawn from the seed, and the body is sculpted as one surface with a face, hair and c
• terrain_heightmapBuilds open country from a seed word and writes its ground as a greyscale PNG (row 0 is north; chunk (i, j) is 128 by 128 tiles). By default the picture is one chunk at 8 bits and black is its lowest tile, white its high
• city_planMakes a city from a seed number and a size (the side of a square, 300 to 2000 metres, 800 by default): streets at varied spacing, closer together toward the centre, some of them curving, some ending at a cross street so
• world_schemaThe ops world_apply accepts (add_zone, add_npc, add_quest, add_link, set_worldgen and the rest), each with its fields as JSON Schema: types, bounds, the closed lists of words and which keys are required. Printed from the
• world_starterA starter world document (two zones joined by a passage, a spawn, no quests) with the id and title given. The title passes the same scrubber world_apply uses: no markup, braces or web addresses. Costs no units.
• world_checkChecks a world document with the engine's strict reader and its spatial rules (every spawn, passage, item and character stands on open ground reachable from the spawn; no two zones overlap; no door is under water). Answe
• world_applyApplies a batch of ops (see world_schema) to a world document, in order. An op that cannot apply is rejected with its reason and changes nothing; if the result as a whole would not be a valid world, the whole batch rolls
• world_heightmapDraws the open country a world document generates (its worldgen block: seed, knobs, regions with their own relief, a ridge) as one greyscale PNG, row 0 north, so a world built with world_apply can be looked at before any
• voice_speakSynthesises a line of English as a 44.1 kHz WAV with the engine's own voice. The voices are synthesised by the engine, never cloned from a recording, and no voice can be uploaded. seed varies the voice; woman, age (0 to
• sound_listThe twenty-one sounds (steps on twelve surfaces, doors and stairs, blows, thunder, splashes, a siren, animal calls, notes and the rest) with what each of a, b and c does, and the seven beds an ambience is mixed from. Cos
• sound_effectRenders one sound from the engine's own synth as a stereo WAV, or an ambience of the beds mixed together. Give sound (a name from sound_list) with a, b and c as sound_list says, or give ambience: any of engine, air, surf
• video_schemaEvery key, range and word a scene document may use: the output, visual tracks of clips (designs, material fills, colours, gradients, titles and shots), the camera, audio (voices, sounds, music) and subtitles. Call this f
• video_presetsThe engine's frame presets (landscape 1920x1080, square 1080x1080, vertical 1080x1920 and their 720 versions) and frame rates. This service renders up to 1920 by 1080 either way up, 30 frames a second and 60 seconds. Cos
• video_examplesWithout a name, lists the example scenes (what each is, what it shows, its length, size and price in units). With a name, returns that scene whole, written inline as video_render wants it: copy the nearest one and change
• video_checkChecks a scene document with the engine's strict reader without rendering it: ok, or one sentence naming the first problem and the key it is at, with every other problem in the scene listed in result.errors (up to fifty)
• video_costReads a scene and reports what rendering it takes (frames, size, design renders, shot frames, audio seconds) and what it costs here: units, and whether it is within this service's limits (60 seconds, 1920 by 1080, 30 fra
• video_stillRenders one frame of a scene at t seconds as a PNG at the scene's size: the way to look at a moment (just after a transition, mid-reveal, the last frame) before rendering the whole video. Costs 1 unit, plus a shot's pric
• video_renderRenders a scene to video.webm (VP9 and Opus), video.wav (its sound) and video.vtt (when it has subtitles); with preview (the default) also video.contact.png, twelve moments on one sheet, and video.preview.gif, 480 pixels
• raster_schemaEvery key and range a shot document may use: the camera (keys or an orbit), the sun, the air and fog, and the subjects (forms, characters, animals, open country and primitives) placed by position or by time keys. The sam
• raster_checkChecks a shot document with the renderer's strict reader: its name, size, subject count and length, or the key that is wrong and why. Forms and materials are named by shipped id or written inline. Costs no units.
• raster_renderRenders a shot (a camera through the engine's world: forms from the sculptor, people and animals from the rig, open country, primitives, under the game's own sky, sun, shadow and haze) at t seconds as shot.png. width and
• pull_schemaEvery document the pull engine reads, with its keys: a session (its generators, their onsets on one integer-nanosecond clock, states, declared intentions, the follower's report and the sealed schedule), a schedule, a pre
• pull_preregReads a pre-registration (what is measured, the conditions, trials per session, sessions, alpha, power, the number of comparisons and the correction) and returns its hash, to record in each session's prereg.hash before t
• pull_analyseAnalyses the sessions of one condition (one session, a list, or {"sessions": [...]}) together, and each alone, and returns the report: its label (significant; null, with the smallest effect these sessions could have foun
