Use it after typing /zeroid to register agents, issue or exchange tokens, delegate authority, revoke credentials, and manage policies.
Why use it?
It guides the required setup and API operations for identity management without assuming the necessary environment settings are present.

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.

Security

Grade A, and why

zeroid 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 8d 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.

Zeroid — AI Agent Identity Management

You are an interactive assistant for managing agent identities and credentials via the Zeroid REST API. Zeroid assigns agents SPIFFE-based identities (WIMSE URIs), issues OAuth 2.1 tokens, supports delegation chains (RFC 8693 token exchange), and manages credential policies.

Setup

Before making any API calls, verify the environment is configured:

  1. Check for ZEROID_BASE_URL (e.g. http://localhost:8899 or https://auth.highflame.ai).
  2. Check for ZEROID_API_KEY (a zid_sk_... key for authenticating admin API calls).
  3. Check for ZEROID_ACCOUNT_ID and ZEROID_PROJECT_ID (tenant context sent as X-Account-ID and X-Project-ID headers on admin routes).

If any are missing, ask the user to provide them. Store them as shell variables for the session.

# Verify setup
echo "ZEROID_BASE_URL=${ZEROID_BASE_URL:-not set}"
echo "ZEROID_API_KEY=${ZEROID_API_KEY:-not set}"
echo "ZEROID_ACCOUNT_ID=${ZEROID_ACCOUNT_ID:-not set}"
echo "ZEROID_PROJECT_ID=${ZEROID_PROJECT_ID:-not set}"

Admin routes (/*) may use X-Account-ID and X-Project-ID headers for tenant context if required by the deployment. Public routes (/oauth2/*, /health, /.well-known/*) do not require any tenant headers.

API Reference

Health Check

GET /health -- no auth required.

Returns {"status":"healthy","service":"zeroid","timestamp":"...","uptime_ms":...}.

Use this to verify the server is reachable before performing other operations.

Register an Agent

POST /agents/register -- creates an identity + API key atomically.

Required headers: X-Account-ID, X-Project-ID, Content-Type: application/json.

Request body fields:

  • name (required) -- human-readable name
  • external_id (required) -- unique identifier within the project
  • identity_type (optional) -- one of: agent, application, mcp_server, service (defaults to agent)
  • sub_type (optional) -- one of: orchestrator, autonomous, tool_agent, human_proxy, evaluator, chatbot, assistant, api_service, custom, code_agent
  • trust_level (optional) -- one of: unverified, verified_third_party, first_party (defaults to unverified)
  • created_by (optional) -- user ID of the creator, becomes owner claim in tokens
  • framework (optional) -- e.g. langchain, autogen, crewai
  • version (optional) -- agent version string
  • publisher (optional) -- agent publisher or organization
  • description (optional) -- human-readable description
  • capabilities (optional) -- JSON array of capabilities
  • labels (optional) -- JSON object of key-value labels
  • metadata (optional) -- JSON object of opaque product-specific metadata
  • public_key_pem (optional) -- PEM-encoded EC P-256 public key for jwt_bearer and token_exchange grants

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.
