# Fediverse NodeInfo Lookup

> Fediverse NodeInfo Lookup 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).

Fetches and parses the NodeInfo document for a Fediverse server, returning software name/version, supported protocols, user statistics, local post counts, registration status, and federation services.

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 fediverse-nodeinfo-lookup-3afea454
```

Example prompt: Can you pull the NodeInfo for mastodon.social and tell me what software it's running, how many active users it has this month, whether registrations are open, and what federation protocols it supports?

## When to prefer this

Choose this endpoint when you need structured, machine-readable intelligence about a specific Fediverse server — including its software stack, user activity statistics, protocol support, and federation configuration — particularly for instance vetting, federation research, or monitoring decentralized social network nodes. Prefer it over manual .well-known lookups or generic HTTP fetchers because it automatically follows the NodeInfo redirect chain, selects the newest supported schema, and normalizes the output.

## Known failure modes

- Server does not host a /.well-known/nodeinfo endpoint — returns error or empty result
- NodeInfo schema version not supported — may fail to parse newer or older schemas
- Server is offline or unreachable — connection timeout error
- Malformed or non-standard NodeInfo document — partial or empty data returned
- Rate limiting or firewall on the target server — request blocked

## How this service works

Fediverse NodeInfo for a server: follows /.well-known/nodeinfo to the newest schema and returns software name and version, supported protocols (activitypub…), total/active-month/active-half-year users, local posts, open registrations, and the server's inbound/outbound services. Instance vetting and federation research. $0.01 per server.

## Output

A structured JSON object containing the server's software name and version, list of supported protocols (e.g. ActivityPub), total registered users, monthly and half-year active user counts, total local posts, whether open registration is enabled, and the server's configured inbound and outbound federation services.
