[ COST / PER_AGENT_ATTRIBUTION ]

How do you track AI agent cost per agent?

Per-agent cost attribution means every dollar of LLM, API, and tool-call spend is tied to the specific agent that spent it, not lumped into a shared cloud bill. Centurian is CFO-grade evidence for AI spend, with x402 stablecoin attribution as a fast-follow for teams already on agentic payment rails.

The bill you have doesn’t answer the question

85% of enterprises lack real-time visibility into AI spend (IBM Institute for Business Value, n=2,000, fielded January-April 2026). That's not a reporting-cadence problem. It's a granularity problem. A cloud invoice or an LLM provider's usage dashboard totals spend by account or API key. When ten agents share a key, which is common, the invoice cannot answer "which agent is burning the budget," only "the account is."

Per-agent cost attribution requires the cost data plane to be built around agent identity from the start, not bolted onto a card or account number after the fact. That's why Centurian's cost attribution is downstream of agent identity: every agent has a registered identity before it spends a dollar, so every dollar has somewhere specific to land.

CFO-grade means the source is never null

Every cost record Centurian writes carries a cost_source tag: OBSERVED (a direct signal from the call itself), PLATFORM_IMPORTED (reconciled from a vendor invoice), AGENT_SELF_REPORTED (declared by the agent), or ESTIMATED (a bounded fallback when no direct signal exists yet). A finance team gets not just a number but a confidence level behind it, the difference between "we measured this" and "we estimated this," on every row.

FinOps for agentic AI is a named Gartner Hype Cycle profile, not a category Centurian invented, agent spend behaves differently from human-driven cloud spend because it can spike autonomously, in seconds, with no procurement step in between. For teams already running agent-to-agent payments, x402 stablecoin spend adds one more rail to the same per-agent record; annualized throughput was roughly $600M in early 2026, real but small next to model-API spend, which is why it's tracked as a fast-follow rather than the headline. See x402 FinOps for that rail specifically.

FAQ

How do you track AI agent cost per agent?

+
Per-agent cost attribution means every dollar of LLM, API, and tool-call spend is tied to the specific agent that spent it, not lumped into a shared cloud bill. Centurian is CFO-grade evidence for AI spend, with x402 stablecoin attribution as a fast-follow for teams already on agentic payment rails.

Why can't a standard cloud bill answer this?

+
85% of enterprises lack real-time visibility into AI spend (IBM Institute for Business Value, n=2,000, fielded Jan-Apr 2026). A cloud bill or an LLM provider invoice shows total spend per account or API key, not per agent, when ten agents share one key, the bill can't tell you which agent is burning the budget.

What does cost_source attribution mean?

+
Every cost record carries a non-null source tag: OBSERVED (direct signal from the call itself), PLATFORM_IMPORTED (reconciled from a vendor invoice), AGENT_SELF_REPORTED (declared by the agent), or ESTIMATED (a bounded fallback when no direct signal exists). A finance team reviewing agent spend can see not just the number but how confident that number is.

Is this a recognized category, or is Centurian inventing it?

+
FinOps for agentic AI is a named Gartner Hype Cycle profile, not a Centurian invention. The category exists because agent spend behaves differently from human-driven cloud spend: it can spike autonomously, in seconds, with no procurement step in between. Per-agent cost attribution is the FinOps primitive that category needs.

What about x402 stablecoin spend specifically?

+
x402 is the emerging HTTP payment protocol for autonomous agent-to-agent payment, and annualized throughput was roughly $600M in early 2026, real, but small next to model-API and tool-call spend. Centurian tracks it as a fast-follow rail for teams already using it, unified into the same per-agent cost record; see /x402-finops for the rail-specific detail.
