Search and Ask

Retrieve normalized web results or get a fast, source-backed answer.

Overview

Reprompt offers two small, complementary web endpoints:

  • Search retrieves normalized web search results for a query. Use it when your application or agent needs the results themselves.
  • Ask retrieves search results and produces a fast, single-hop narrative answer grounded in those results. Use it when your user needs a concise answer with sources.

Both endpoints accept the same minimal body. There are no filters, modes, or structured search inputs at launch.

Ask is a fast grounded-answer endpoint, not a deep-research workflow. It does not perform multi-step research or replace source review for high-stakes decisions.

Authentication and base URL

Create an API key in Organization Settings → API Keys, then send it as a bearer token. Reprompt resolves the organization from the authenticated API key, so no organization identifier is required in the URL.

https://api.repromptai.com/v1

Send a natural-language query to POST /search. The response is a stable, normalized result list; it intentionally does not expose the underlying search-provider response.

curl --request POST \
  --url 'https://api.repromptai.com/v1/search' \
  --header 'Authorization: Bearer {YOUR_API_KEY}' \
  --header 'Content-Type: application/json' \
  --data '{
    "query": "What is the difference between a web search API and a research agent?"
  }'

Search response

{
  "query": "What is the difference between a web search API and a research agent?",
  "answer_box": {
    "answer": "A web search API retrieves ranked web results.",
    "url": "https://example.com/search-apis"
  },
  "results": [
    {
      "title": "Example result title",
      "url": "https://example.com/search-vs-research",
      "snippet": "A short excerpt describing the result.",
      "position": 1,
      "date": "2026-07-25"
    }
  ]
}

Each item in results has a stable normalized shape:

FieldTypeDescription
titlestringResult title.
urlstringCanonical result URL.
snippetstring, optionalSearch-result excerpt.
positionintegerOne-based rank in the returned result set.
datestring, optionalDate supplied by the result, when available.

The results array can be empty when no results match the query.

When the search provider supplies them, the response can also include:

  • answer_box — a direct answer or featured snippet with its source URL.
  • knowledge_graph — entity information such as a title, type, description, website, and scalar facts.

These objects are optional. Build agent logic around results unless it explicitly benefits from enriched search features.

Ask

Send the same query to POST /ask to receive a concise narrative answer plus the source objects used to ground it. Reprompt uses DeepSeek V4 Flash through OpenRouter for this endpoint.

curl --request POST \
  --url 'https://api.repromptai.com/v1/ask' \
  --header 'Authorization: Bearer {YOUR_API_KEY}' \
  --header 'Content-Type: application/json' \
  --data '{
    "query": "What is the difference between a web search API and a research agent?"
  }'

Ask response

{
  "query": "What is the difference between a web search API and a research agent?",
  "answer": "A web search API returns relevant documents for a query. A research agent typically uses search as one step in a larger, multi-step process that evaluates sources and synthesizes a response. [1]",
  "sources": [
    {
      "title": "Example result title",
      "url": "https://example.com/search-vs-research",
      "snippet": "A short excerpt describing the result.",
      "position": 1,
      "date": "2026-07-25"
    }
  ]
}

sources uses the same normalized source-object shape as Search results. Render the source URLs alongside the answer so people can inspect the evidence themselves.

Errors and retries

Both endpoints return JSON errors. Handle these status codes:

StatusMeaningWhat to do
401The API key is missing, invalid, or revoked.Create or use an active API key.
403The authenticated account cannot access the endpoint.Verify the feature is enabled for the account.
422The request is invalid, including a missing, blank, or extra input field; Ask also uses this when no web results are available.Correct the request; do not retry unchanged input.
429The account has exceeded a rate or usage limit.Retry with exponential backoff and respect Retry-After when present.
502Ask could not produce a citation-backed answer from the retrieved sources.Retry once or reformulate the query.
503A search or answer provider is temporarily unavailable.Retry idempotently with exponential backoff and respect Retry-After.
