About the Text Summarizer API

Text Summarizer works by analyzing the text provided and generating a concise summary. It uses advanced algorithms and ai models to identify key points and generate a summary that captures the essence of the text.

What people use it for

Content Summarization: Use the Text Summarizer API to summarize content for easy reading. Use the data to generate summaries, extract key points, and condense information
Information Extraction: Summarize information by using the Text Summarizer API to extract key points. Use the data to identify important details, highlight key insights, and condense data
Document Summarization: Summarize documents by using the Text Summarizer API to generate summaries. Use the data to condense text, extract key information, and summarize reports
Text Analysis: Analyze text by using the Text Summarizer API to generate summaries. Use the data to study language patterns, identify themes, and classify content

Ways to call it

One endpoint, many ways in — REST with JSON, XML, YAML and CSV, plus GraphQL and an MCP interface for AI agents.

JSON: Default REST response
XML: Markup format
YAML: Human-readable
CSV: Tabular export
GraphQL: Query language
MCP: For AI agents

Give it to an AI agentConnect over MCP and your agent calls it as a native tool — Claude, Cursor, ChatGPT.on VerveKit Google Sheets or ExcelA =VERVE() formula fills a column — no script, no export, recalculates in place.on VerveSheets

Questions.

Common questions about the Text Summarizer API.

Read the docs →

What does the Text Summarizer API do?

Text Summarizer is a simple tool for summarizing text. It returns a summary of the text.

How do I authenticate Text Summarizer API requests?

Pass your API key in the x-api-key header over HTTPS. One key works across all 300+ APIVerve APIs — there are no per-endpoint credentials.

How much does the Text Summarizer API cost?

Each call spends 20 credits from your shared pool. The free tier includes 200 credits every month, and paid plans add more headroom.

How fast is the Text Summarizer API?

Response time depends on the endpoint — the p50 through p99 latency for this API is published on this page. Requests are served over HTTPS through a global edge network.

What response formats does the Text Summarizer API support?

JSON by default, plus XML and YAML via the format parameter. GraphQL and an MCP interface for AI agents are available across the catalog.

What HTTP method does the Text Summarizer API use?

POST over HTTPS, following standard REST conventions with a consistent { status, error, data } response envelope.

Request parameters — POST /v1/textsummarizer

Sent as JSON in the request body. Premium parameters are accepted on every plan but only take effect on plans that include them. Anything not listed here is dropped rather than passed through.

Required

Parameter	Type	Example	Description
`text`Required	string	`Artificial intelligence is transforming industries worldwide. Machine learning algorithms can now process vast amounts of data to identify patterns and make predictions. This technology is being applied in healthcare, finance, transportation, and many other sectors.`	The text to summarize (up to 5000 characters) length 0-50000

Optional

Parameter	Type	Example	Description
`sentences`Optional	number	`3`	The length of the summary (number of sentences) default 3

Example request

curl -X POST "https://api.apiverve.com/v1/textsummarizer" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text":"A news article can include accounts of eyewitnesses to the happening event. It can contain photographs, accounts, statistics, graphs, recollections, interviews, polls, debates on the topic, etc. Headlines can be used to focus the reader'\''s attention on a particular (or main) part of the article. The writer can also give facts and detailed information following answers to general questions like who, what, when, where, why and how.","sentences":2}'

Authentication

Send your key in the x-api-key header. That is the only auth step — no token exchange, and no per-endpoint scope to configure.

Header	When	Value
`x-api-key`Required	Every request	Your API key. Header names are case-insensitive, so `X-API-Key` is the same header.
`Authorization`Alternate	Instead of the above	`Bearer <key>` — for clients that only expose bearer auth. Resolves to the same account and the same billing.
`content-type`Required	POST body	`application/json`

401 is the only auth verdict

A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.

Response — POST /v1/textsummarizer

Every APIVerve endpoint returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape.

Sample response

{
  "status": "ok",
  "error": null,
  "data": {
    "originalWords": 67,
    "summaryWords": 30,
    "percentDifference": 44.78,
    "summary": "Headlines can be used to focus the reader's attention on a particular (or main) part of the article. A news article can include accounts of eyewitnesses to the happening event."
  }
}

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Field	Type	Example	Description
`originalWords`Premium	number	`67`	Total word count in the original text input
`summaryWords`Premium	number	`30`	Total word count in the generated summary output
`percentDifference`Premium	number	`44.78`	Percentage reduction from original to summary text
`summary`	string	`"Headlines can be used to focus the reader's attention on a particular (or main) part of the article. A news article can include accounts of…`	The condensed text summary capturing key points

Response headers

Every response carries your balance, so your own code always knows where it stands without polling anything. All four are exposed to browsers through CORS.

Header	What it carries
`x-api-remaining-credits`	Credits left in the current cycle
`x-api-credits-used`	Credits spent in the current cycle
`x-api-max-credits`	The allowance for the cycle
`x-api-version`	Version of the endpoint that answered

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change.

Status	Meaning	What to do
`400`	Input was rejected	Read `error`; it names the parameter that has to change.
`401`	Key missing or invalid	Check the header name and the key value.
`403`	Key valid, but not permitted here	A key restriction or an IP allow-list — never a bad key.
`429`	Rate limited, or out of credits	Read `error` to tell them apart, then back off or top up.

What a call costs — 20 credits per call

Credits are shared across every APIVerve API — one balance, one key, one bill. Failed requests never count against it, so a rejected input costs nothing.

Plan	Per month	Credits	Text Summarizer calls	Per 1,000 calls
Free	Free	200	10	Free
Starter	$29.99	200,000	10,000	$3.00
Pro	$99.99	1,000,000	50,000	$2.00
Mega	$299.99	4,000,000	200,000	$1.50

Calls are what the credits buy at this API's rate — spend them here, on any of the other APIs, or across both. Nothing is reserved per endpoint.
