# Search scholarly papers by keyword. Returns a normalized Paper page.

`POST /v2/ops/academic.paper.search`

## Request

- Base URL: `https://api.agentkey.app`
- URL: `https://api.agentkey.app/v2/ops/academic.paper.search`
- Auth: HTTP bearer

Keyword search over Google Scholar (via Serper) and AMiner; the server picks the source and fails over. sort=recent / citations routes to AMiner, which can order that way.

Fixed price: 0.2 credits per successful call, whichever provider serves it.

## Request body

- object
  - `cursor` string: Opaque pagination cursor from the previous response's next_cursor. Send the same query parameters with it.
  - `fields` string[]: Projection: keep only these dotted paths of data, e.g. ["items.id", "items.text"].
  - `include_raw` boolean: Attach the raw upstream payload as `raw` (not a stable contract; truncated above 256 KB).
  - `limit` integer: Maximum number of papers to return.
  - `provider` string: Shorthand for routing.only = [provider].
  - `query` string, required: Topic, title words or free-text question.
  - `routing` Routing: Provider routing override. order: try these providers first; only: restrict to these (equivalent to pinning); allow_fallbacks: false tries only the first eligible provider.
    - `allow_fallbacks` boolean: false = try only the first eligible provider.
    - `only` string[]: Restrict to these providers.
    - `order` string[]: Providers to try first, in order.
    - `strategy` 'auto': How eligible providers are ordered. auto = the method's curated order. fastest / stable / popular are specified but not implemented yet (400 until then). The price is fixed whatever the strategy; mutually exclusive with order.
  - `sort` 'relevance' | 'recent' | 'citations': relevance = best match; recent = newest first; citations = most cited first.

## Response `200`

Success envelope

- PaperPageEnvelope: Success envelope whose data is a PaperPage.
  - `attempts` Attempt[], required
    - `error_type` string: validation | not_found | rate_limit | timeout | upstream_unauthorized | upstream_unavailable | provider_error
    - `provider` string, required: Provider slug.
    - `refunded` boolean: true when the reservation for this attempt was refunded.
    - `status` integer, required: HTTP status AgentKey mapped this attempt to (200 on success).
    - `took_ms` integer, required
    - `tool` string, required: Registry tool name (Provider/operation) that was called.
    - `upstream_status` integer: The provider's real HTTP status; absent when nothing was received.
  - `credits_charged` number, required: Credits charged for this call (the method's fixed price).
  - `data` object, required: One page of papers.
    - `items` Paper[], required
      - `abstract` string, nullable, required: Abstract or snippet as plain text.
      - `arxiv_id` string, nullable, required: arXiv identifier (2307.12307) when known.
      - `authors` string[], nullable, required: Author names in listed order (Google Scholar shows only the first few of a long list).
      - `citations_count` integer, nullable, required: Citation count as the provider reports it.
      - `doi` string, nullable, required: DOI when known.
      - `id` string, required: Provider-scoped paper id: arXiv id (alphaXiv), AMiner id (24 hex chars) or Google Scholar result id. arXiv and AMiner ids can be passed to academic.paper.get.
      - `pdf_url` string, nullable, required: Direct PDF URL when known.
      - `published_at` string, nullable, required: Publication date as the provider reports it: YYYY-MM-DD, YYYY-MM or YYYY.
      - `title` string, required: Paper title.
      - `url` string, nullable, required: Landing page URL (arXiv abstract, publisher page, provider page).
      - `venue` string, nullable, required: Journal / conference name when reported.
    - `next_cursor` string, nullable, required: Opaque cursor for the next page; null when exhausted or the provider cannot page.
  - `op` string, required: Method name.
  - `op_version` integer, required: Method version that served the call.
  - `provider` string, required: Provider that actually served the call.
  - `raw` unknown
  - `raw_truncated` boolean
  - `request_id` string, required: Correlation id; quote it in support requests.
  - `took_ms` integer, required
  - `unsupported_fields` string[], required: Output paths this provider structurally does not supply; such fields are null for a different reason than 'missing on this record'.
