Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00035 | $0.01009 |
| Opus 5 | $0.00017 | $0.00504 |
| Sonnet 5 | $0.00007 | $0.00202 |
| Haiku 4.5 | $0.00003 | $0.00101 |
Grade A, and why
api-usage 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 2d 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.

Prizmad REST API
Prizmad provides a REST API for creating AI-powered video ads programmatically. The MCP server at /api/mcp is a thin agent-friendly wrapper on top of these endpoints — anything the MCP layer does, you can do with a curl loop.
Authentication
Three interchangeable ways to obtain a Bearer token. See /.well-known/agent-skills/oauth/SKILL.md for the full OAuth spec.
Option 1: API key (simplest)
Authorization: Bearer przmad_sk_live_...
Manage keys at https://prizmad.com/api-keys.
Option 2: OAuth 2.0 client_credentials (server-to-server)
curl -X POST https://prizmad.com/oauth/token \
-d grant_type=client_credentials \
-d client_id=my-app \
-d client_secret=przmad_sk_live_...
Returns access_token (HS256 JWT, 1 h, audience https://prizmad.com/api).
Option 3: OAuth 2.1 Authorization Code + PKCE + DCR (Connect flow)
The "Add custom connector" path used by Claude Desktop / Claude.ai / ChatGPT / Cursor. RS256 JWT bound to the MCP audience, refresh-rotated. Discovery: /.well-known/oauth-authorization-server.

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.
