API Access

JSON API

Access RPKI data programmatically. Current snapshots are free; historical data requires an Organization tier API key.

Route Validation (RFC 6811)

GET /any53/rpki/api/validate/?prefix=193.0.0.0/21&asn=3333
curl -sS "https://www.any53.com/any53/rpki/api/validate/?prefix=193.0.0.0/21&asn=3333" | jq .
{
  "prefix": "193.0.0.0/21",

  }
}

List ROAs by ASN

GET /any53/rpki/api/roas/?asn=3333
curl -sS "https://www.any53.com/any53/rpki/api/roas/?asn=3333" | jq .

Covering/Contained Prefixes

GET /any53/rpki/api/roas/covering/193.0.0.0/24/
# Less-specific (covering) ROAs
curl -sS "https://www.any53.com/any53/rpki/api/roas/covering/193.0.0.0/24/" | jq .

# More-specific (contained) ROAs
curl -sS "https://www.any53.com/any53/rpki/api/roas/contained/193.0.0.0/16/" | jq .

ROA Change History

Track when ROAs were added, removed, or modified. Requires Organization tier.

About RPKI

Resource Public Key Infrastructure (RPKI) enables network operators to cryptographically attest to the IP prefixes they are authorized to originate.

A Route Origin Authorization (ROA) binds an IP prefix to an AS number, allowing routers to validate BGP announcements and reject hijacks.

Trust Anchor Coverage

Data sourced from the five Regional Internet Registry trust anchors.
