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

fundraiseup 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.

Pagination Best Practices

All list endpoints use cursor-based pagination:

  1. Initial Request: Set limit parameter (1-100)
  2. Next Page: Use the last item's id in starting_after
  3. Previous Page: Use the first item's id in ending_before
  4. Sorting: Records sorted by creation date (newest first), then by ID (Z to A)
