Bitnodes API v1.0

All API endpoints are available for public use without any authentication required. Requests originating from the same IP address is limited to a maximum of 300 requests per day.

Requests made using authenticated API key is limited to a maximum of 50,000 requests per day. Authenticated API key access is available to users on PRO plan only. Python code sample to perform authenticated API request: sample-bitnodes-auth-api-client.py

The remaining limit you have available for the day is included in the ratelimit-remaining response header. Subsequent request after ratelimit-remaining: 0 will result in HTTP 429 Too Many Requests response with retry-after response header containing waiting time in seconds before your daily limit is restored.

Available endpoints:

List snapshots
List nodes
List addresses
Node status
Node latency
Leaderboard
Node ranking
List data propagation
Data propagation
DNS seeder

New snapshot is generally available approximately every 10 minutes, so it is recommended that periodical requests are made at most every 10 minutes. Timestamps used in requests and responses are in Unix time in seconds unless specified otherwise in the documentation below.

Parameters:

field (optional) - Specify field=coordinates to get the list of unique latitude and longitude pairs or field=user_agents to get the list of unique user agents instead of the full information listed below.

Pagination parameters are not available for this endpoint, as it simply returns the raw snapshot from the export directory used by the crawler. Values in each array in the response represent the following information:

DNS Seeder

Get a list of reachable nodes to bootstrap your Bitcoin client connection to the Bitcoin network. The DNS records are generated using seeder.py.

DNS <RECORD> <PREFIX>seed.bitnodes.io

IPv4 nodes are returned via A records, IPv6 nodes are returned via AAAA records and .onion nodes are returned via TXT records.

seed.bitnodes.io returns a list of reachable nodes with NODE_NETWORK (1) service bit set. Prefix x[hex] is accepted to filter nodes by specific services. For example, x409.seed.bitnodes.io returns a list of reachable nodes with services set to 1033 (hex(1033) = '0x409'), i.e. NODE_NETWORK (1), NODE_WITNESS (8), NODE_NETWORK_LIMITED (1024).
