Streaming LLM Usage Settlement Decision Procedure (K-2SO x402)
x402
Streaming LLM Usage Settlement Decision Procedure (K-2SO x402) is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-29).
Returns an LLM-generated prose decision procedure for agents evaluating how to settle streaming LLM usage costs, delivered as a paid x402 API on Base.

How this service works
Deterministic decision procedure for settling streaming LLM usage over x402/MPP. Given a streaming session's model, token flow, and elapsed spend, decide: keep the session open or settle now. Uses per-token cost drift gates (settle when projected session cost exceeds budget fraction or observed token rate diverges from quoted price by more than the drift threshold), interruption handling (mid-stream failure refund thresholds and retry-versus-settle rules), real-time cost visibility checks
Output
A JSON object containing a boolean success flag, payment confirmation, the provider name (K-2SO), a plain-prose decision procedure of 120+ words, the LLM model used to generate it, the topic, a generation source enum (llm/reasoning/deterministic), and an ISO-8601 timestamp of when it was generated.
Example use cases
Agent billing policy for LLM inference
“My autonomous agent uses a streaming LLM API and I need a clear decision procedure it can follow to determine when and how to settle those usage costs — can you fetch the K-2SO guidance on streaming LLM usage settlement?”
Auditing agent cost governance
“I'm building a compliance layer for my agent fleet and I need the official decision procedure text for streaming LLM usage settlement so I can embed it into our agent's cost-governance logic.”
Custom topic override for LLM billing policy
“Fetch the streaming LLM usage settlement decision procedure but override the topic to focus specifically on per-request micropayment settlement for real-time inference workloads.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/streaming-llm-usage-settlement-decision-procedur?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a ready-made, LLM-authored decision procedure specifically for streaming LLM usage cost settlement, payable per-call via x402 USDC micropayments on Base. Prefer it over static documentation when you want dynamically generated, agent-consumable prose that can be topic-overridden and is always fresh with a generation timestamp.
Side effects
- HTTP 402 returned when no payment or incorrect payment is provided — must settle exact USDC and retry with PAYMENT-SIGNATURE header
- Invalid or missing query parameters may yield an error or default behavior
- Network errors or agent merchant downtime at k2so.wrong.systems
- Malformed payment signature rejected by the x402 facilitator
- Topic override ignored if the service slug has a fixed deterministic procedure
