Technical details
Endpoint
POSThttps://proxy.suverse.io/v1/data/suverse-countries-cnow-capitalWhen to prefer
Use this endpoint when you need a single, complete, no-key-required reference list of all world countries with capital cities and ISO codes. Ideal for populating dropdowns, building lookup tables, or enriching datasets without needing to set up a credentials-based geography API. Prefer over full geography APIs when you only need the country/capital/code reference data and want a simple one-call solution.
Side effects
- Upstream countriesnow.space API unavailability causes proxy failure
- Payment not received or x402 flow incomplete results in 402 response
- Malformed POST body may return a 400 error
- Occasional stale or outdated capital city data if upstream source is not refreshed
