A Cortex REST API skill for working with notes, search, graphs, data ingestion, compilation, bulk ingestion, and feedbacks through HTTP routes. REST is a common way for programs to communicate with web services using requests such as GET and POST.

Use it when writing curl commands or HTTP clients, changing FastAPI routes, inspecting OpenAPI documentation, troubleshooting logs, or keeping REST and MCP behavior aligned.

It provides the route locations, authentication rules, logging guidance, and shared behavior needed to work on or call the API. It also warns that many REST operations share logic with the MCP interface.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00044	$0.00520
Opus 5	$0.00022	$0.00260
Sonnet 5	$0.00009	$0.00104
Haiku 4.5	$0.00004	$0.00052

Security

Grade A, and why

cortex-api scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

What it actually says

Cortex REST API

Router: cortex/api/routes.py, mounted at /api/v1 in cortex/main.py.

OpenAPI: http://localhost:8420/docs

Authentication

When AUTH_METHOD is not none, protected routes require:

x-api-key: <API_KEY> when apikey, or
Authorization: Bearer <token> when oidc (API key also accepted as fallback)

Unprotected prefixes (cortex/auth/middleware.py):

/api/v1/health, /api/v1/login, /api/v1/auth/callback
/mcp, /.well-known/, /docs, /redoc, /openapi.json

Logging

Stream	Source	Example
stdout	`uvicorn.access`	`INFO: … "GET /api/v1/graph/stats" 200 OK`
stderr	`cortex.*` loggers	`INFO [cortex.api.routes] Bulk ingest request received: …`

Tail both: docker logs <container> 2>&1 | grep bulk

App logging configured in cortex/main.py via logging.basicConfig.

Shared logic with MCP

Many endpoints call the same functions as MCP (cortex/mcp/tools.py) or vault modules directly. Changing behavior usually requires updating both surfaces.

Endpoint summary

See reference.md for method, path, and tags.

Common request bodies

Feedback (POST /feedbacks):

{
  "content": "…",
  "tags": ["admin-review"],
  "related_paths": ["wiki/article.md"]
}

Bulk ingest (POST /bulk-ingest):

{
  "source_dir": "/ingest",
  "concurrency": 4,
  "force": false,
  "dry_run": false
}

source_dir must exist on the server filesystem (e.g. /ingest in Docker, not a host path).

MCP: cortex-mcp
Auth: cortex-auth
Compiler endpoints: cortex-compiler

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cortex-api is a skill published in the GitHub repository synpulse8-opensource/pulse8-ai-cortex-knowledge-vault (14 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 44 tokens to every session and 520 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
