Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability neural-interface-event-metrics-e94c5a9e -d '<json body>'
```

Example prompt: Score these 50 labelled time intervals and 80 command events from our synthetic BCI dataset — the session ran for 120000 milliseconds, data class is synthetic, and there are no participant identifiers — and give me the false activation counts, missed trial rates, wrong commands, and first-correct response times.

## When to prefer this

Choose this endpoint when you need to compute standardized performance metrics (false activations, missed trials, wrong commands, first-correct response times) for brain-computer interface or neural interface event data using only public or synthetic metadata — not raw EEG signals. Ideal for BCI researchers, neurotechnology developers, and simulation pipelines that need reproducible scoring of command event sequences without transmitting any personally identifiable participant data.

## Known failure modes

- Exceeding 128 command events or 64 intervals returns a validation error
- Submitting raw EEG data or participant identifiers is rejected
- dataClass must be 'public' or 'synthetic'; any other value is invalid
- noParticipantIdentifiers must be set to true; omitting or setting false causes rejection
- durationMs outside 1–86400000ms range is invalid
- Empty intervals array (minItems:1) causes rejection

## How this service works

Score up to 64 labelled time intervals and 128 command events: rest false activations, missed trials, wrong commands and first-correct response times. Public or synthetic event metadata only. No raw EEG, participant identifiers, live control, diagnosis or human-enhancement claim. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

## Output

Returns computed performance metrics for the submitted neural interface event data, including false activation counts for rest periods, missed trial counts, wrong command rates, and first-correct response times for each scored interval and event batch. Results are retained for 24 hours with minimal receipt metadata retained for 90 days.
