Request body
JSON, posted to this endpoint.
- promptstring
what is the capital of australia and why
The question or prompt for Microsoft Copilot to answer using Bing web search.
- requireFieldsarray
Optional; omit it and routing is unchanged, with the cheapest source serving. Name the output fields this request must be able to return, for example `answerMarkdown`, `inlineCitations` or `tables`, and it is served only by a source that returns every one of them. Fields you do not name are still returned whenever the serving source has them. This can raise your price: when the cheapest source cannot return a named field, a dearer source serves, and you are quoted and charged its price. A named field can still be absent on an answer that genuinely lacks it. Naming a combination that no single source returns together is refused as invalid input, with no charge.
Response
JSON, one example value per field.
The answer and its sources, or null when Copilot returned no answer.
- additionalSectionsstring[]can require
Text of answer sections Copilot rendered outside the main answer, such as a section heading or a card, kept so nothing it showed is lost. null means the source that answered cannot report them.
- answerstring
Copilot's answer as text. Citation markers Copilot places inline can appear as numbers or source names next to the words they support. Populated whenever the provider has data for the entity.
- answerMarkdownstringcan require
Copilot's answer in Markdown, keeping its bold text, lists and tables. null means the source that answered returns plain text only; name answerMarkdown in requireFields to be served only by a source that returns it.
- completebooleancan require
Whether Copilot finished the answer. false means the answer may be cut short. null means the source that answered cannot report it, which is not the same as true.
- promptstring
The prompt Copilot answered.
Sources Copilot cites for the answer, in the order it lists them. Populated whenever the provider has data for the entity.
- domainstringcan require
Host of the source page as Copilot shows it, e.g. blog.salesflare.com. null means the source that answered cannot report it.
- snippetstring
Excerpt of the source page Copilot shows. null when Copilot shows none or the source that answered cannot report it.
- titlestring
Source page title, empty when Copilot shows none.
- urlstring
Source page URL. Populated whenever the provider has data for the entity.
Each claim in the answer that Copilot ties to a source, with the source it cites. null means the source that answered cannot report them.
- textstringcan require
The sentence of the answer the citation supports.
- titlestring
Title of the cited source, empty when Copilot shows none.
- urlstring
URL of the cited source.
Products, brands or options Copilot recommends in the answer, each with the sentence that recommends it. null means the source that answered cannot report them.
- namestringcan require
Name of the recommended product, brand or option.
- textstringcan require
The sentence of the answer that recommends it.
Pages Copilot searched while researching the answer. A different list from citations: a page here was read but is not necessarily cited. null means the source that answered cannot report them.
- snippetstring
Excerpt of the page Copilot shows, null when it shows none.
- titlestring
Title of the page, empty when Copilot shows none.
- urlstring
URL of the page.
Tables in the answer, e.g. a comparison table. null means the source that answered cannot report them.
- captionstringcan require
Table caption, null when the table has none.
- headersstring[]can require
Column headers.
- rowsstring[][]can require
Table rows, each a list of cell texts in column order.
- foundboolean
Whether Copilot returned an answer.
- reason"not_found"
Present only when `found` is false, and says why there is no result. `not_found`: the source states the target does not exist, or returned nothing for it. A `found: false` answer is a successful call, not an error, and `costUsd` is what it actually cost.
