How this service works
What is the actual answer to this question, according to the live web right now? Runs a multi-engine search, reads the top pages, and returns one synthesised answer with inline [1][2] citations and the source URLs behind them — the whole search-read-summarise loop in a single paid call instead of a dozen
Output
A JSON object containing a synthesized natural-language answer with inline citation numbers, the search engine used (DuckDuckGo), a list of up to 8 source URLs with titles mapped to citation numbers, and the underlying LLM provider name.
Example use cases
ERC-20 token safety check
“Look up whether the ERC-20 token contract 0xdAC17F958D2ee523a2206206994597C13D831ec7 has been flagged for any honeypot behavior or rug-pull risks — check up to 6 sources and give me a concise answer.”
OFAC sanctions wallet screening
“Search the web and tell me if the crypto wallet address 0x7F367cC41522cE07553e823bf3be79A889debe1B appears on any OFAC sanctions lists or known blacklists — keep the answer under 300 words.”
DeFi protocol TVL and yield lookup
“What are the current total value locked figures and best yield opportunities on Aave and Compound right now? Pull from up to 8 sources and give me a thorough answer.”
Technical details
Endpoint
POSThttps://eltociear-tokenguard.hf.space/llm/answerWhen to prefer
Choose this endpoint when you need a synthesized, cited natural-language answer about crypto/DeFi topics — especially ERC-20 token safety, OFAC sanctions screening, or DeFi analytics — and want live web evidence rather than a static database lookup. Prefer it over raw search APIs when you need the answer synthesized into prose with citations, and over static on-chain data APIs when you need broader contextual or news coverage.
Side effects
- Query too vague or off-topic returns a low-quality or generic answer
- max_sources set to 0 or invalid integer may cause a parameter error
- Live web search may return stale or inaccurate information for rapidly changing on-chain data
- Payment failure (HTTP 402) if x402 micropayment is not properly authorized before the call
- Rate limiting or Hugging Face Spaces cold-start latency may cause timeouts
- Contract addresses not indexed by public web may yield no useful sources
