An agent driving Blender made its concepts, meshes and render reviews
through a tool server of the game's own, which called this gateway; the
gateway's MCP server offered only the memory notes. It now offers
generate_image, generate_mesh, review_images, run_workflow, job_status and
gateway_status beside them, each only where a model for it is here.
Each tool makes its request of the client API as the caller, through the
handler Handler built, key check and all: allowlists, limits, licences
left out, budgets and accounting apply as to any request, and a job is
the caller's. What a tool makes is kept as the caller's file and answered
by id and download URL, since a server over HTTP cannot write to the
caller's disk; a picture comes with a 512 px preview, and whole where no
file can be kept. A picture to work from is a file id, a data URL or
base64; one sent to the vision model is shrunk to 1280 px.
A mesh takes minutes. A client that takes a stream is answered as
server-sent events, with notifications/progress for its token while the
job is queued, waiting for the GPU and running, and waits up to ten
minutes; one that does not waits 50 seconds and gets the job id, which
job_status asks after.

A model's catalog entry now says what its workflow takes and makes:
comfyui.inputs, each a placeholder of its name with a type (text, int,
float, bool, choice, image, mask, audio, video, file), bounds, choices
and a default; and comfyui.output, which gains video, audio and files
beside pictures and meshes. POST /v1/workflows/runs with {model, inputs}
checks a request against them before a job is written — a required input
left out, an unknown one, a number out of bounds, a song sent as a
picture, another owner's file id are each refused with what was wrong —
and the job worker replays it to a replica, where the files go into
ComfyUI's input directory, the workflow is filled and run, and the first
file of the model's output kind is the job's result. /v1/models lists
each ComfyUI model's workflow, so a client can build its form.
A PNG result carries the licence in an iTXt chunk, as a GLB does in
asset.extras. A file whose server named no type is typed by its name
before its bytes, so a WAV is audio/wav, not audio/wave.

LLMGWPrepareForMesh, llmgw's own ComfyUI node, written by the gate into
every replica's custom_nodes from the binary: TripoSR's own preparation
(tsr/utils.py) — the background taken away, by the picture's alpha where
it has one and by rembg (MIT; u2net, Apache 2.0) where it does not, the
object cropped to its bounds, set square at a ratio of the side (0.85),
on grey. A picture sent as it was had a white or black shell round the
object, whatever was behind it made into the mesh.
/v1/models listed only models with a replica up, so one that loads when
asked — triposr, flux-schnell — was invisible to the clients that would
have asked for it. Those are listed now, with loaded: false; every entry
says loaded.

/v1/openapi.json is the API clients use — OpenAI's endpoints, Anthropic's,
and what llmgw adds — in OpenAPI 3.1, generated from internal/clientapi's
route table by the generator the admin API's document comes from, now
told each document's title, server, token and error. A test reads the
router's mux.HandleFunc calls and refuses a route described and not
mounted, or mounted and not described. Asked for before there is a key,
so it needs none.
/docs/api shows it in Swagger UI 5.33.1 (Apache 2.0, served from the
gateway as the page's policy requires): Authorize takes a key, Try it out
sends to this gateway. Staff are offered the admin API's document too,
from /docs/api/admin.json, which nobody else is given.
