AI Gateway Metering and Licensing
The
Prisma AIRS AI Gateway employs a
consumption-based metering model. All AI traffic, including MCP, LLM, and A2A
payloads routed through the Gateway is measured in
Tokens.
Token consumption calculation:
- Prompts (Request/Responses) - Token values returned by the LLM.
- MCP Tool calls - Industry-standard conversion rate of 1 Token per 4
plaintext (UTF-8) characters.
- A2A requests - Industry-standard conversion rate of 1 Token per 4
plaintext (UTF-8) characters.
This standard applies consistently across both SaaS and Hybrid deployment
environments.
Licensing Structure
In alignment with the broader Prisma AIRS portfolio (including AI
Runtime, Model Scanning, and Red Teaming), the AI Gateway utilizes
Software NGFW credits for
licensing. Total credit requirements are estimated based on your
organization’s anticipated token usage.
This model includes built-in tiered volume discounts, so as you
reach higher usage tiers, the cost per billion tokens decreases. The more
you scale, the fewer Flex Credits you'll spend on usage in those higher
tiers.
Self-Service Tool: Palo Alto Networks is building an
interactive Flex Credit Calculator to convert your projected token usage
into required credits instantly.
