Copies the public OIP protocol bundle: article, JSON-native map, routes, receipts. No owner token.

§SELF — protocol specification
## §SELF — OIP protocol specification

**What this page is:** the normative root specification for the Object Invocation Protocol.

**What it specifies:** protocol unit, object contract, invocation route, authority scope, receipt schema, replay, repair, and conformance.

**Read:** https://miscsubjects.com/a/oip-system-grok
**Machine bundle:** https://miscsubjects.com/api/articles/oip-system-grok/bundle?format=markdown
**Live object tree:** https://miscsubjects.com/api/dispatch?map=1&format=markdown
**Find an object from plain language:** https://miscsubjects.com/api/dispatch?ask=<what you want>
**Read one object:** https://miscsubjects.com/api/dispatch?key=<KEY>&format=markdown

**Proof rule:** an action is not proven by intent, description, or a 200. It is proven by the ledger and the OIP receipt for the invocation.

Grok / xAI

A generated article for one OIP shelf. It lists every operation in this API/CLI/MCP/device/model/core subsystem, links each leaf article, and gives the ledger path for proof.

This page is the operating article for one build subsystem. It is generated from live directory rows. If a task belongs to this subsystem, scan the operations below, open the matching capability article, run only the exact object named there, and verify by receipt.

Kind: model. Capabilities: 9. Machine system map: /api/dispatch?map=GROK&format=markdown. Root: /a/oip.

Operations

GROK_LEDGER_TAIL

Invokable OIP capability. Human article: /a/oip-capability-grok-ledger-tail. Machine doc: ?key=GROK_LEDGER_TAIL&format=markdown. Invocation history: /api/invocations?object_id=GROK_LEDGER_TAIL.

GROK_IMAGE

Generate an image from a text prompt. Returns a JSON url (grok-imagine-image-quality, $0.05/image). Use when: any "make/generate/create an image, picture, photo, or art" request. The whole body is the prompt. Arguments: prompt (free text). Human article: /a/oip-capability-grok-image. Machine doc: ?key=GROK_IMAGE&format=markdown. Invocation history: /api/invocations?object_id=GROK_IMAGE.

GROK_IMAGE_EDIT

Edit an image with natural language. Returns a JSON url Use when: you need to grok image edit Arguments: prompt|image_url. Human article: /a/oip-capability-grok-image-edit. Machine doc: ?key=GROK_IMAGE_EDIT&format=markdown. Invocation history: /api/invocations?object_id=GROK_IMAGE_EDIT.

GROK_VIDEO_START

Start a text-to-video job. Returns request_id. Poll with GROK_VIDEO_GET. Model grok-imagine-video ($0.05/sec) Use when: you need to grok video start Arguments: prompt|duration_seconds(1-15). Human article: /a/oip-capability-grok-video-start. Machine doc: ?key=GROK_VIDEO_START&format=markdown. Invocation history: /api/invocations?object_id=GROK_VIDEO_START.

GROK_VIDEO_GET

Poll a video job. status pending|done|failed|expired; when done returns video.url Use when: you need to grok video get Arguments: request_id. Human article: /a/oip-capability-grok-video-get. Machine doc: ?key=GROK_VIDEO_GET&format=markdown. Invocation history: /api/invocations?object_id=GROK_VIDEO_GET.

GROK_MODELS

List every model on the xAI API. No args Use when: you need to grok models Arguments: see content. Human article: /a/oip-capability-grok-models. Machine doc: ?key=GROK_MODELS&format=markdown. Invocation history: /api/invocations?object_id=GROK_MODELS.

GROK_TTS

Text-to-SPEECH (Grok). INVOKE: GROK_TTS]<text>|<voice_id>[/GROK_TTS] Use when: you need to grok tts Arguments: see content. Human article: [/a/oip-capability-grok-tts. Machine doc: ?key=GROK_TTS&format=markdown. Invocation history: /api/invocations?object_id=GROK_TTS.

GROK_STT

Speech-to-TEXT (Grok). INVOKE: GROK_STT]<public_audio_url>[/GROK_STT] Use when: you need to grok stt Arguments: $1. Human article: [/a/oip-capability-grok-stt. Machine doc: ?key=GROK_STT&format=markdown. Invocation history: /api/invocations?object_id=GROK_STT.

GROK_IMAGE_R2

Generate an image with Grok Imagine, re-store it to R2, and return a stable https://miscsubjects.com/img/ link. Use when: you need an image; prefer this over GROK_IMAGE because it returns a stable URL. Arguments: prompt. Human article: /a/oip-capability-grok-image-r2. Machine doc: ?key=GROK_IMAGE_R2&format=markdown. Invocation history: /api/invocations?object_id=GROK_IMAGE_R2.

system
The OIP article layer is generated from live directory rows, so it documents the objects that actually run the reference implementation.
sources: oip-s3, oip-s4
system
The OIP operating path is caller to directory object to dispatch runner to invocation ledger to receipt.
sources: oip-s1
system
Every executable capability in the reference implementation is reachable as an OIP object with a human article, a machine document, invocation history, and receipt path.
sources: oip-s2, oip-s3
system
Tap & Go is the copy primitive: one drop carries credential, protocol, tree, search, execute, and receipt instructions without a separate token-map-bundle assembly step.
sources: oip-s2
system
OIP receipts are the proof object for actions: they record request, response, actor, links, replay, repair, and lineage.
sources: oip-s2, oip-s5
