Execution API usage
Request volume, errors and latency — and the two things Tessen cannot yet tell you.
Your own request volume, error rate, latency percentiles and per-key activity are real and readable. The endpoint is scoped to the caller; there is no user parameter.
Cost
The execution API's usage endpoint reports request volume, errors and latency, not cost. For the cost of model requests on Tessen's families, read the wallet ledger and the final streamed frame; see Wallet and usage.
Intelligence units
There is no normalized unit of Tessen intelligence, and raw provider token counts are not one. Nothing in this documentation converts an execution into units, and no multiplier or rate is published, because none is defined. Token counts are shown where they exist, labelled as the technical consumption they are.
