# Matrix Homeserver Check

> Matrix Homeserver Check is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Probes a Matrix homeserver's federation delegation, client discovery, server software/version, and registration/login flows via well-known endpoints

## Facts

- Endpoint: GET https://intel.rallylive.ca/dev/matrix-server
- 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/matrix-homeserver-check-8bab995a
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_nu4oLU-n_X9we8R5DFx7f

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 matrix-homeserver-check-8bab995a
```

Example prompt: Can you check the Matrix homeserver at matrix.example.org and tell me what server software and version it's running, whether federation is properly configured, and what login flows it supports?

## When to prefer this

Use this endpoint when you need to programmatically inspect a Matrix homeserver's configuration, software stack, or federation readiness — especially useful for Matrix server operators, federation troubleshooting, or building directories of Matrix homeservers. Prefer this over generic HTTP probing tools when you specifically need Matrix protocol semantics (well-known delegation, federation version API, login flow enumeration).

## Known failure modes

- Domain does not host a Matrix homeserver — well-known endpoints return 404 or non-JSON
- Federation endpoint unreachable on delegated host — network timeout or firewall block
- Well-known endpoints return malformed JSON — parsing errors reported
- Server uses non-standard port or certificate issues causing TLS failures
- Rate limiting or IP blocking on the target server preventing probe

## How this service works

Matrix homeserver check: reads /.well-known/matrix/server (federation delegation) and /.well-known/matrix/client (client base URL, identity server), probes the federation version endpoint on the delegated host, and returns server software/version, whether federation and client discovery are configured, and registration/login flows advertised. $0.01 per server.

## Output

Returns the Matrix server software name and version detected via the federation version endpoint, whether /.well-known/matrix/server (federation delegation) and /.well-known/matrix/client (client discovery) are configured, the delegated federation host, client base URL, identity server URL, and the registration and login flows advertised by the server.
