Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-extract/hashtags/t10?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, low-cost ($0.03 USDC) extraction of the top 10 ranked hashtags from a text block of up to 50,000 characters, especially in autonomous agent pipelines that use x402 micropayment rails on Base. Ideal when you want a fixed-size top-10 hashtag set rather than an open-ended or configurable count.
Side effects
- Text exceeds 50,000 character limit — request rejected or truncated
- Empty or whitespace-only text input yields no hashtags
- Payment failure via x402 on Base blockchain prevents endpoint access
- Text with no discernible topics may return fewer than 10 hashtags
- Non-English or mixed-language text may produce lower quality results
