AI answers, as data.
One API returns the answers the consumer apps show for ChatGPT, Perplexity, Gemini, Microsoft Copilot, Grok, Google AI Mode, Google Search, and Google News — every source, citation and product card parsed into JSON. Request a country, or a US state.

Engines
Every answer engine, one schema
ChatGPT
The answer ChatGPT gives real users, with every cited source, the searches it ran, product cards and brand mentions.
PPerplexity
Perplexity's answer with its citations, related queries, the searches it ran, and any videos, images, places, hotels or shopping cards it showed.
GGemini
Gemini's grounded answer with its sources, inline citations and places.
CMicrosoft Copilot
Copilot's Bing-grounded answer with its sources, the searches it ran, shopping cards and map results.
GGrok
Grok's answer with its cited sources, including X posts, and the searches it ran.
AGoogle AI Mode
Google's conversational AI Mode answer with citation pills, places, shopping cards, inline products, videos and ads.
SGoogle Search
Structured Google results: organic listings, ads, People Also Ask, knowledge graph, local pack and the AI Overview.
NGoogle News
Google News results for any query, country and interface language, up to ten pages deep.
Why it matters
The model API is not what users see
Provider APIs return a completion. The consumer apps answer differently — they search the web, cite pages and show product cards. We capture the real experience, so you measure what customers actually read.
Provider API response
{ "choices": [{ "message": { "content": "For small agencies, the most…" }}] }
What the user saw
"For small agencies, the most recommended options are HubSpot, Monday and Notion…"

Agents
Give your agent the data
The hosted MCP server exposes every engine as a tool. One command and Claude, Cursor or any MCP client can ask ChatGPT or search Google mid-task.
$ claude mcp add --transport http answerline \
https://mcp.answerline.dev/mcp \
--header "Authorization: Bearer $API_KEY"How it works
Prompt in, structured data out
Send a prompt
Pick an engine, a prompt and a country. Call it synchronously or queue thousands of tasks at once.
We run it live
The prompt runs against the consumer product, routed through a proxy for the location you chose, and retries automatically if it has to.
Get structured JSON
Answer text, markdown, sources, search queries, shopping cards and entities, in the same shape every time.
Pay for successes
Credits are charged only when a result is delivered. Failed runs cost nothing.
Built for volume
Infrastructure, not a dashboard
Async batches
Submit up to 500 tasks per call with priorities, idempotency keys and webhooks — poll or get pushed results.
Fair queues
Every account has its own concurrency slots and queue, and accounts take turns for workers.
Geo-targeted
The API accepts 250 country codes on every engine, US states for AI assistants and city-level locations for Google; results reflect the location of the proxy the request is routed through.
Works with your tools
REST with an OpenAPI spec, a hosted MCP server for agents, SDKs for Python and TypeScript, n8n and Zapier.

Questions
Is this the official OpenAI or Google API?
No. Official model APIs don't return what the consumer apps show users: the web-search answers, citations, shopping cards and ads. This API returns what people actually see.
What happens if a request fails?
It is retried automatically. If it still fails, you get an error and no credits are charged.
Do unused credits roll over?
No. Credits reset at the start of each billing cycle.
