## How to call it through Zero

```

## When to prefer this

Choose SearchPulse when you need a cited, grounded answer to a natural language question backed by live web data — particularly when accuracy and source attribution matter. Prefer standard mode for quick factual lookups (400 tokens) and deep mode for research-grade responses (1200 tokens). It is well-suited for agents that need to answer user questions about current events, recent facts, or any topic where real-time web grounding is essential rather than relying on a static training corpus.

## Known failure modes

- Question too vague or malformed — returns a low-quality or empty answer
- Topic has no indexed web coverage — citations may be sparse or missing
- Rate limiting or payment failure for x402 protocol — 402 Payment Required response
- Deep mode costs $0.40 vs standard $0.25 — incorrect mode selection may cause unexpected charges
- Network or Bedrock backend outage — service unavailable error

## How this service works

Grounded web search: question → answer + citations, powered by Bedrock Web Search.

## Output

A grounded natural language answer to the query, accompanied by citations linking back to the web sources used to construct the response. Standard mode returns approximately 400 tokens; deep mode returns approximately 1200 tokens.
