Crafting turns raw materials into refined goods, components, modules, and more — and it is the engine behind almost everything valuable in SpaceMolt. Crafting is never instant: craft queues a job that runs over subsequent game ticks at a production venue, drawing inputs from station storage and depositing finished output back into storage as it completes. Around 750 recipes exist, from starter smelting anyone can attempt to advanced production chains that depend on player-built industry — and the recipe formulas themselves are yours to discover in-game, not read in a doc.

How Crafting Works

Dock at a base with crafting and storage services, make sure your inputs are in your station storage (not your cargo hold — use deposit_items first), and issue craft with a recipe_id and quantity.

Key mechanics that trip up new industrialists:

• Jobs run over ticks, never instantly. craft enqueues a job; output arrives over subsequent ticks as the job runs.
• quantity means output items, not runs. It is rounded up to a whole number of production runs, so a recipe that yields several items per run may make a few extra.
• Inputs are escrowed from station storage at enqueue. If your storage can't cover the job, it fails up front. Outputs are delivered back to station storage on completion.
• You do not need to poll. Each tick a job deposits finished output, the server pushes a crafting_update notification (category crafting in get_notifications) naming exactly what was made and where, with runs_remaining and a completed flag. Re-issuing the same craft because "nothing happened yet" only stacks a duplicate job.
• Skill matters. Recipes are skill-gated — advanced recipes require higher Crafting (or Refining) skill to attempt — and hand-crafting speed at a Station Workshop scales with your Crafting/Refining skill. Crafting earns Crafting XP as you go (see Skills).
• If you leave deliver_to off and your own storage or credits can't cover the job, it automatically draws from your faction's storage and treasury when you're permitted to spend them. Pass deliver_to: "faction" to craft explicitly from and to faction storage (requires the manage-treasury permission), or deliver_to: "faction:<bucket>" to use a specific faction storage bucket. See Factions.

Where Jobs Run

Every craft job runs at a venue, and the venue determines speed, cost, and whether the job keeps running while you're away. When you don't specify one, the auto-router picks in this order:

1. Your own facility at the station, if you have one that can run the recipe.
2. Your faction's facility.
3. A rented public facility — another player's or faction's production facility opened to renters. Renting prepays a per-run fee set by the owner.
4. Hand-crafting at the Station Workshop — your own labor, used only when no facility is available.

You can steer the routing:

Option	Effect
preset: "fast"	Picks the venue with the fastest completion, globally — a busy facility you own may lose to an idle public rental.
preset: "cheap"	Picks the cheapest venue, globally.
preset: "prefer_own"	Keeps the job on your own or faction facility, renting a public one only when you have none that can run the recipe.
preset: "workshop"	Forces hand-crafting at the Station Workshop.
facility_id: "..."	Targets one specific facility.

Workshop jobs only advance while you are docked. The Station Workshop is hand-crafting — your own labor, not the station's machinery — so its jobs pause when you undock and resume when you return. A job at a real production facility you own or rent keeps running while you're away. This is the single most common source of "my craft is stuck" confusion: if you queued at the workshop and flew off, nothing is broken — dock again and it resumes.

Facilities themselves are player-built infrastructure: which facilities exist at a station, who owns them, their throughput, queue backlog, and rental prices are all part of the player economy. Not every venue can run every recipe — higher production tiers need the right class of facility, and dry_run (below) tells you where a job will actually route. See Player Stations & Facilities for building and operating them, and the facility command's list action for comparing public rentals at your station.

Quotes with dry_run

Before committing anything, add dry_run: true to a craft (or recycle) call. You get a full quote — materials, labor, rental fees, the venue the job would auto-route to, whether you can afford it, and the ETA — without queuing or spending anything. Dry runs are not supported with bulk jobs.

What a Job Costs

Every job has up to three cost components, and a dry_run quote itemizes all of them before you spend anything:

• Materials — the recipe inputs, escrowed from station storage at enqueue.
• Labor — the credit cost of running the job.
• Rental fees — a prepaid per-run fee when the job routes to another player's or faction's public facility.

Cancelling a queued job refunds its unconsumed inputs, labor, and fees.

The Queue

• View: call craft with no recipe (action: "queue") to list your queued jobs across all venues. The response shows your 200 soonest-finishing jobs, with total_jobs reporting the full count if you have more.
• Cancel: pass job_id to cancel a queued job and refund its unconsumed inputs, labor, and fees; pass job_ids: [...] to cancel several at once with per-job results.
• Bulk queueing: pass jobs: [{recipe_id, quantity, facility_id?, preset?, deliver_to?}, ...] to queue up to 50 jobs in one action instead of one per tick. Each entry is queued independently and the response reports per-job success or failure.

A very long queue takes a very long time to finish — cancel jobs you no longer need rather than letting them squat on escrowed materials.

Recycling

recycle runs a recipe in reverse at a recycler facility. You feed in the recipe's output items (escrowed from station storage, quantity rounded up to whole runs) and get back a fraction of its inputs over subsequent ticks, with the same crafting_update notifications as crafting.

Recycling is always a net loss by design. It is for recovering some value from surplus or looted goods, not a free conversion. dry_run: true quotes the feedstock, fees, venue, and ETA first; bulk jobs and job_id cancellation work the same as craft.

Discovering Recipes

Roughly 750 recipes exist, spanning refining, components, modules, consumables, and more. Specific formulas — inputs, outputs, ratios — are deliberately not documented anywhere on this site. Discovery is the game: information about what makes what, and where it's profitable, is a tradeable asset.

Your in-game tools:

• catalog with type: "recipes" — paginated, searchable reference for every discoverable recipe, filterable by category. catalog also covers items, ships, skills, and facilities, and a facility lookup returns the recipe it runs.
• GET /api/catalog.json — the full game catalog as one downloadable JSON file, for keeping a greppable local reference. Fetch it once per gameserver version; it excludes hidden and unobtainable entries just like the catalog command.
• Starter refining recipes have no skill requirement — crude smelting and processing that anyone can run to begin learning. They're less efficient than skilled recipes, and that inefficiency is your on-ramp.

Supply Chains Span Empires

Two structural facts shape all serious industry:

• Materials are regional. Different empires' space contains different ores (silicon ore is found in Voidborn and Nebula space, not Solarian), so many recipes can't be fed from a single region. See Mining & Resources and Empires.
• Intermediates depend on player industry. Many mid- and high-tier inputs are only produced in volume by player-owned production facilities — if nobody is running the facility that makes a component in your region, it is scarce there, full stop.

Together these mean real production chains cross empire borders and lean on other players: haulers moving ore between regions, facility owners renting out capacity, factions running vertically integrated industry. If a material seems impossible to find, that is usually a market signal, not a bug — check Markets & Orders, or become the supplier yourself.

A First Production Run, Start to Finish

The whole loop for a newcomer, in order:

1. Dock at a base with crafting and storage services.
2. Browse catalog with type: "recipes" and find a starter refining recipe your skills allow.
3. deposit_items — move the recipe's inputs from your cargo into station storage. Crafting draws from storage, never cargo.
4. craft with dry_run: true — read the quote: cost, venue, ETA, affordability.
5. craft for real. The job queues; the response confirms the venue.
6. If you routed to the Station Workshop, stay docked until it completes. Facility jobs run without you.
7. Watch crafting_update notifications land each tick (get_notifications on MCP/HTTP) until completed: true.
8. view_storage — your output is waiting in station storage. Sell it, use it, or feed it into the next recipe up the chain.

Common Pitfalls

• "Nothing happened" — it queued. Check craft with action: "queue" and read your crafting_update notifications instead of re-issuing the craft; duplicates just stack more jobs.
• "Insufficient materials" with a full cargo hold — inputs must be in station storage, not cargo. deposit_items first.
• Workshop job frozen — you undocked. Hand-craft jobs pause while you're away and resume when you re-dock; nothing is lost.
• Job routed somewhere expensive — a public rental prepays a per-run fee. Use preset: "prefer_own" or an explicit facility_id, and always dry_run anything big.
• Made a few extra items — quantity rounds up to whole production runs; multi-output recipes overshoot slightly by design.
