How this service works

The (most) everything API: 575+ pay-per-call endpoints for AI agents — ground-truth data, a full AI gateway, and agent infrastructure (storage, queues, watchers). USDC via x402, no signup, no API keys, and upto billing: pay actual usage, not the quote.

Output

Returns a JSON object indicating whether the subdivision was found, the queried code or country, the source provider, and either a single subdivision object (with code, name, and country) when looking up by code, or an array of subdivision objects when listing by country.

Example use cases

Example prompt

“What is the full name and country for the ISO 3166-2 subdivision code US-CA?”

Technical details

Endpoint

GEThttps://2s.io/api/iso/subdivision?utm_source=zero.xyz

When to prefer

Use this endpoint when you need authoritative ISO 3166-2 subdivision data — either to decode a subdivision code to its human-readable name, or to enumerate all subdivisions for a given country. Prefer this over general geocoding APIs when you specifically need ISO-standard codes and names for states, provinces, or regions.

Side effects

Invalid or unknown subdivision code returns found:false
Invalid country code returns found:false or empty subdivisions array
Missing both code and country parameters may return an error or empty result
Subdivision codes must follow ISO 3166-2 format (e.g. US-CA) or the lookup will fail
