# Relaystation Media Probe

> Relaystation Media Probe is a paid API for AI agents from api.relaystation.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Inspects any media file via ffprobe and returns duration, container format, streams, codecs, dimensions, and bitrate as structured JSON

## Facts

- Endpoint: POST https://api.relaystation.ai/v1/media/probe
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/relaystation-media-probe-0a66ece8
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_VvAoc1Iks3mDWBV_9yjxP

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 relaystation-media-probe-0a66ece8 -d '<json body>'
```

Example prompt: Can you probe this video file at https://example.com/myvideo.mp4 and tell me its duration, codec, resolution, and bitrate?

## When to prefer this

Use this endpoint when you need fast, structured technical metadata about any media file without downloading or processing it yourself. It is ideal for pre-flight validation of user uploads, quality checks in media pipelines, or feeding codec/dimension data into downstream transcoding decisions. Prefer this over manual ffprobe invocations when operating in a serverless or agent context that cannot run local binaries.

## Known failure modes

- Unreachable or invalid media URL returns an error with no probe data
- Unsupported or corrupted file format may return partial or empty stream info
- Very large files may time out before probing completes
- Non-media files (e.g. plain HTML pages) return an error indicating no media streams found

## How this service works

$0.0002/call. Inspect any media file via ffprobe — duration, container, streams, codecs, dimensions, bitrate as JSON. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny

## Output

A JSON object containing the full ffprobe output: container format name, duration in seconds, overall bitrate, and an array of stream objects each with codec name, codec type (video/audio), dimensions (width/height for video), sample rate and channel layout (for audio), and other technical parameters.
