Example use cases

Simplified to traditional conversion

Endpoint
GEThttps://china-trends-x402.onrender.com/v1/zh?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pay-per-call, no-signup Pinyin romanization service that also returns simplified/traditional variants and tone numbers in a single call, especially when integrating with x402 USDC micropayment flows on Base. Prefer it over subscription-based Chinese NLP APIs for low-volume, on-demand transliteration tasks where avoiding API key management is valuable.
Side effects
- Non-Chinese or empty text input may return unexpected results or an error
- Text exceeding 2000 characters is rejected by the schema
- Payment failure via x402 returns a 402 status before any data is served
- Network latency on Render free-tier hosting may cause timeouts under load
