What it does

NodeInfo is a fixed two-hop, no-auth, pure-JSON handshake:

GET https://<host>/.well-known/nodeinfo → a links[] list pointing to a versioned NodeInfo document.
GET the highest-version document (2.1 › 2.0 › 1.x) → software name & version, protocols, services, registration policy, and real usage stats.

Give it a list of hosts; it runs both hops for each and returns one flat row per instance.

Input

{
  "instances": ["mastodon.social", "https://lemmy.world", "misskey.io"]
}

Field	Type	Description
`instances`	array (required)	Bare hostnames or base URLs. Each is normalized to its host and queried at `/.well-known/nodeinfo`.
`userAgent`	string	Optional custom User-Agent (some instances 403 a default UA).
`extraHeaders`	object	Optional extra HTTP headers for gated deployments. Never required for public instances; never logged.

Output

One dataset row per instance:

Column	Description
`host`	The instance host queried
`software_name` / `software_version`	e.g. `mastodon` / `4.6.3`
`software_repository` / `software_homepage`	Source links when advertised (2.1)
`protocols`	e.g. `["activitypub"]`
`services_inbound` / `services_outbound`	Federated services (e.g. RSS/Atom feeds)
`open_registrations`	Whether signups are open
`total_users`	Total registered users
`active_month` / `active_halfyear`	Monthly / half-year active users
`local_posts` / `local_comments`	Local content counts
`node_name` / `node_description`	Free-form instance metadata
`nodeinfo_version` / `schema_rel`	Which NodeInfo schema version was read
`_raw`	The lossless raw NodeInfo JSON

Example row (mastodon.social):

{
  "host": "mastodon.social",
  "software_name": "mastodon",
  "software_version": "4.6.3",
  "protocols": ["activitypub"],
  "open_registrations": true,
  "total_users": 3332491,
  "active_month": 268351,
  "active_halfyear": 704364,
  "local_posts": 180270111,
  "local_comments": null,
  "node_name": "Mastodon",
  "nodeinfo_version": "2.0"
}

Generic by design

Instances differ only in which optional fields they populate, and every field is read by key presence — so a server that omits activeMonth (Misskey serves it null), has no local_comments (Mastodon), or ships an empty metadata block (Lemmy) yields null for that column instead of failing. Unreachable hosts and non-NodeInfo servers are skipped with a warning and the batch continues.

Pricing

Pay-per-event: one charge per instance row returned.

Use cases

Fediverse census / research: compare software, versions, and activity across a set of instances.
Instance-picking: check registration status, size, and activity before joining or recommending an instance.
Monitoring: track a watchlist of instances' software versions and user growth over time.
Migration/federation planning: enumerate the software and protocols a peer set runs.
