Technical details
Endpoint
GEThttps://tradeapex.ai/x402/related?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, fast semantic concept expansion without the overhead of transformer-based embeddings. It is well-suited for finance and trading domain vocabulary, keyword enrichment, or any scenario where you want to discover conceptually related terms from a proprietary self-derived semantic model. Prefer it over general-purpose embedding APIs when cost per call and simplicity matter, and when the domain of interest aligns with TradeAPEX's training corpus.
Side effects
- Input term contains non-letter characters — only English letters are accepted
- Term is unknown to the model — returns empty or no results but is not charged
- k parameter out of range (must be 1–25) — request rejected
- Missing required 'term' query parameter — returns error
- Non-GET HTTP method used — unsupported method error
