GET /api/anchors/catalog
Returns a list of active Stellar anchors with their capabilities and operational status.
Query parameters
Filter by country code (ISO 3166-1 alpha-2, e.g., “US”, “PH”). Case-insensitive.
Filter by anchor type: on-ramp or off-ramp
If true, only return anchors with operational: true (full SEP-10 and SEP-24 support)
Response
Array of anchor objects
Anchor home domain (e.g., “stellar.moneygram.com”)
ISO 3166-1 alpha-2 country code
Primary currency code (e.g., “USD”, “PHP”)
Anchor type: “on-ramp” (deposit) or “off-ramp” (withdraw)
Whether anchor is fully operational (has SEP-10 and SEP-24 endpoints)
Stellar Ecosystem Proposal support flags
SEP-10 authentication support
SEP-24 interactive deposits/withdrawals
SEP-6 programmatic deposits/withdrawals
SEP-31 cross-border payments
ISO 8601 timestamp of last capability check

Filtering examples
Operational US on-ramps
curl "https://api.payonproof.com/api/anchors/catalog?country=US&type=on-ramp&operationalOnly=true"
All Philippine anchors
curl "https://api.payonproof.com/api/anchors/catalog?country=PH"
SEP-24 enabled anchors
const { anchors } = await fetch('/api/anchors/catalog?operationalOnly=true')
.then(r => r.json());
const sep24Anchors = anchors.filter(a => a.sep.sep24);
Implementation notes
- Anchors are sourced from the Stellar anchor directory and Horizon network
- Capabilities are refreshed periodically via background jobs
operational: true requires both SEP-10 (authentication) and SEP-24 (interactive flows)- Invalid filter values (e.g.,
type=invalid) will exclude all results for that filter
- Country codes are normalized to uppercase for comparison
