How this service works
Keyword & Entity Extraction: extract keywords, entities and topics from text Executed deterministically by the AmanChain node against live consensus state (real blocks, pools, balances) — paid per call via x402, settled in USDC on Base. Input: JSON body {"serviceId":"aman-keywords","request":"<input>"}. No account, no API key.
Output
A structured response containing extracted keywords (important terms), named entities (people, organizations, locations, products, etc.), and identified topics found within the input text.
Example use cases
Tag news article for content indexing
“Extract all the keywords, entities, and topics from this news paragraph so I can index it: 'The European Central Bank raised interest rates by 25 basis points on Thursday, citing persistent inflation across the eurozone. President Christine Lagarde said further hikes are possible.'”
Enrich product reviews with key terms
“Pull out the main keywords and any named entities from this customer review: 'The Sony WH-1000XM5 headphones have incredible noise cancellation but the carrying case feels cheap compared to Bose.'”
Identify topics in research abstract
“What are the key entities and topics in this abstract? 'Researchers at MIT and Stanford have developed a novel CRISPR-based therapy targeting BRCA1 mutations, showing a 40% reduction in tumor growth in murine models.'”

POSThttps://preview-chat-701ec510-82d7-4ee3-ae9d-8fdb8c4f421b.space-z.ai/api/x402/aman-keywordsWhen to prefer
Choose this endpoint when you need lightweight, pay-per-call keyword and entity extraction without managing API keys or subscriptions. Ideal for agents processing arbitrary text in automated pipelines where cost predictability (fixed USDC micro-payment) matters. Best suited for single-document NLP enrichment tasks rather than bulk batch processing.
Side effects
- Empty or very short input text may yield few or no results
- Non-English text may produce lower-quality extractions
- Payment failure via x402 will block the call
- Malformed JSON body or missing serviceId field returns an error
- Extremely long inputs may be truncated or cause timeouts
