# Humanoid FMEA Query — Decision Data Studio

> Humanoid FMEA Query — Decision Data Studio is a paid API for AI agents from api.ikoles.dev, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Queries a curated FMEA (Failure Mode and Effects Analysis) dataset for humanoid robots, returning ranked failure modes, risk priority numbers, and recommended controls filtered by subsystem, priority, or evidence type.

## Facts

- Endpoint: POST https://api.ikoles.dev/v1/humanoid-fmea-query
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

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 humanoid-fmea-query-decision-data-studio-d129b352 -d '<json body>'
```

Example prompt: Search the humanoid robot FMEA database for High-priority design-layer failure modes related to battery fire with an RPN of at least 30, and return up to 5 records.

## When to prefer this

Choose this endpoint when you need structured, curated FMEA data specifically for humanoid robots — covering both design-review and evidence-backed failure modes — with filterable risk priority numbers, subsystem tags, and recommended controls. Prefer it over generic safety databases when you need machine-callable, agent-friendly FMEA retrieval with per-record source attribution and hazard metadata. It is not a substitute for certified field reliability data or professional safety approvals.

## Known failure modes

- Query string too long (exceeds 200 characters) — request rejected
- minRpn out of range (below 0 or above 1000) — validation error
- limit out of range (below 1 or above 20) — clamped or rejected
- Invalid enum value for layer or priority — bad request error
- No records match the specified filters — empty records array returned
- Service unavailable or payment not processed — 402 or 5xx error

## How this service works

Local-first data and agent workflow tools from Decision Data Studio, plus verified EU tender shortlists and machine-callable utilities.

## Output

Returns a JSON object containing matched FMEA records for humanoid robots, each with: failure mode description, subsystem, function, local and system effects, hazard, severity/occurrence/detection scores, computed RPN, priority level, recommended controls, existing detection methods, verification tests, evidence type and strength, source URL and title, and a single-point failure candidate flag. Also includes metadata: total matched records, returned count, dataset version, generation timestamp, active filters, and a CC BY 4.0 license notice with a disclaimer that results are preliminary research data, not professional safety certification.
