Agent-Service Metering & Marketplace Economics

Note (dated 2026-08-04): a chain composes independent computations performed in an analytical order. No step's output is carried into the next step by the execution model; each step computes from its own declared inputs. This is true of every chain on this site, including chains whose per-step copy below reads as a data handoff.

W-D. Metering + marketplace unit economics (ART-63) -> x402 settlement cost/finality (art-03) -> usage/billing anomaly monitoring (ml-03). Models the economics of an agent-service micropayment marketplace. Educational estimator.

Question: Our metering feed watches for billing anomalies. If the series carries six injected spikes, how many periods get flagged? Run the AINumbers MCP tool `run_chain` with {"chain":"agent-economy-metering"} and read `ml-03-timeseries-anomaly-detector.anomalies_flagged`. Re-run with `inputs` for `ml-03-timeseries-anomaly-detector`, reusing the values that result echoed, with `nAnomalies` set to 6. Compare the same field. Verify: call `verify_execution_hash` (https://mcp.ainumbers.co/mcp) with `claimed_hash` set to `composite_execution_hash` and the full `composite_artifact`. Ledger, for a human re-check: https://ledger.ainumbers.co/ PII rule: send synthetic or anonymised inputs only. The MCP server runs these kernels and logs no payloads.
