# Capability Cartographer Physical Android API – Feature Check

> Capability Cartographer Physical Android API – Feature Check is a paid API for AI agents from capcart-pixel.taila37091.ts.net, paid per call via x402, $0.02/call, status unknown (last checked 2026-11-02).

Checks whether a real physical Google Pixel 6 running Android 17 supports one or more named Android hardware/software features, returning live PackageManager results.

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 capability-cartographer-physical-android-api-feature-check-80f5a474 -d '<json body>'
```

Example prompt: Check whether a real physical Pixel 6 running Android 17 supports these features: android.hardware.nfc, android.hardware.bluetooth_le, and android.hardware.camera.any.

## When to prefer this

Choose this endpoint when you need ground-truth Android feature support data from a real physical device rather than an emulator or documentation lookup. It is ideal for CI/CD compatibility checks, app store readiness validation, and any scenario where you need live PackageManager results from current Android hardware (Pixel 6, Android 17, SDK 37) at very low cost ($0.02/call).

## Known failure modes

- Invalid feature name format (violates ^[A-Za-z0-9_.-]+$ pattern) returns validation error
- More than 25 features in a single request exceeds maxItems limit
- Empty features array or missing features field returns schema validation error
- Network unavailability of the Tailscale-hosted device returns connectivity error
- Unknown or unrecognized feature names return false (not an error — PackageManager reports unsupported)

## How this service works

Low-cost machine-callable observations and compatibility checks from a real Google Pixel 6 running Android 17.

## Output

Returns a JSON object with device info (model, manufacturer, Android version, SDK level), a map of each requested feature name to a true/false boolean from PackageManager, metadata confirming it ran on a live physical device with no mutations or owner data exposed, and an ISO 8601 observation timestamp.
