How this service works
Hallo Welt der Nexari GmbH: kleinster bezahlter Test-Endpunkt, gibt Gruß, Zeit und gezahlten Betrag zurück. Hello world from Germany: smallest paid x402 smoke test, returns greeting, timestamp and paid amount. Voraussetzung/required: accept_terms_hash, business_name (B2B) – /legal/terms.json
Output
Returns a JSON object containing a greeting string, the current server timestamp, and the amount paid for the call. Confirms the x402 payment was processed successfully.
Example use cases
x402 integration smoke test
“I just set up my x402 wallet and want to verify everything works — can you call the Nexari hello endpoint for my company 'TestCorp GmbH' with my accepted terms hash and confirm I get a greeting and timestamp back?”
Cheapest paid API call verification
“Run the smallest possible paid API call on Nexari to confirm my agent can handle x402 micropayments — use business name 'Beta Labs GmbH' and include the terms hash from /legal/terms.json.”
B2B agent payment capability check
“Before I deploy my agent fleet, can you do a $0.001 test call to Nexari's hello-world endpoint acting on behalf of 'Startup AG' to confirm the x402 payment and response handling is all working?”
Technical details
Endpoint
GEThttps://x402.nexari.cloud/hello?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the cheapest and simplest way to verify that an x402 micropayment client is correctly configured — it is the minimal viable paid call in the Nexari ecosystem. Prefer it over other Nexari endpoints when the goal is integration testing, not actual business data retrieval. Ideal for developers or agent builders confirming end-to-end x402 payment flow before deploying more expensive capabilities.
Side effects
- Missing or invalid accept_terms_hash returns an error — must be SHA-256 of /legal/terms.json
- Missing business_name query parameter causes rejection since it is required for B2B calls
- Payment failure or insufficient USDC balance results in 402 Payment Required with no data
- Invalid HTTP method (POST, PUT, etc.) returns method-not-allowed since only GET/HEAD/DELETE are accepted
- Expired or mismatched terms hash may be rejected if terms have been updated
