How this service works
309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.
Output
A JSON object with ok: true and paid: true, plus a list of world countries (names and possibly codes or metadata), returned deterministically for every paid call.
Example use cases
Country dropdown for onboarding form
“Pull the complete list of countries so I can populate the country selector on my user registration form.”
Validate user-submitted country name
“I have a user who entered 'Deutchland' as their country — can you fetch the official countries list so we can check if it matches anything?”
Build a geography quiz dataset
“Fetch me all the world's countries so I can use them as answer options in a geography trivia game I'm building.”

Endpoint
GEThttps://x402-toolbox.shablony-pro.workers.dev/geo/countries-list?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, no-signup, pay-per-call reference list of world countries and don't want to manage API keys or subscriptions. Ideal for AI agents operating autonomously with USDC on Base via x402 protocol. Prefer over free alternatives when you need guaranteed determinism and micropayment-native access patterns.
Side effects
- Payment not included or insufficient — HTTP 402 returned, endpoint not served
- Invalid schema parameter — may return malformed or unexpected response
- Network timeout on Cloudflare Workers edge — transient, retry recommended
- No countries returned if underlying data source is misconfigured — check ok field
