# netintel.dev Text Summarize > netintel.dev Text Summarize is a paid API for AI agents from netintel.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-13). Summarizes a block of text into a concise, graded summary with key points, compression ratio, and word counts ## Facts - Endpoint: POST https://netintel.dev/text-summarize - Price: $0.005/call - Payment: x402 - Status: unknown - Last checked: 2026-09-13 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/netintel-dev-text-summarize-79d5751f - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_DrXI9kfSRpbPa2xWYNw8k Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability netintel-dev-text-summarize-79d5751f -d '' ``` Example prompt: Can you summarize this article for me and pull out the key points: 'The James Webb Space Telescope has completed its first year of science operations, delivering breakthroughs across exoplanet atmospheres, the early universe, and stellar nurseries. Scientists say the data has already overturned several long-held assumptions about galaxy formation.' ## When to prefer this Choose this endpoint when you need a quick, graded prose summary with structured key points and compression metrics from arbitrary text. Prefer it over generic LLM summarization when you want a consistent JSON schema including grade, score, and compression ratio, and when cost-per-call micropayment pricing is acceptable. ## Known failure modes - Empty or missing text body returns a 400 error - Text too short to meaningfully summarize may return a low-quality or trivial summary - Payment not included or insufficient USDC triggers a 402 Payment Required response - Very long texts may exceed token limits and return a truncation or error response - Non-English or mixed-language input may degrade summary quality ## How this service works Text summarizer / summarization API — condense text, Markdown, or a URL into a TL;DR plus key bullet points using Claude Haiku. Accepts raw text or a URL (fetched and extracted), enforces an input cap, and returns a clean structured summary so agents can compress documents and articles in one call. ## Output Returns a JSON object with a letter grade (A-F), numeric score (0-100), the source label, a concise prose summary, an array of key points, a findings array, the compression ratio, summary word count, and original word count. ## Request schema (JSON Schema) ```json { "$schema": "https://json-schema.org/draft/2020-12/schema", "type": "object", "properties": { "input": { "type": "object", "properties": { "type": { "type": "string", "const": "http" }, "method": { "type": "string", "enum": [ "POST" ] }, "bodyType": { "type": "string", "enum": [ "json", "form-data", "text" ] }, "body": { "type": "object", "properties": { "text": { "type": "string", "description": "Raw text to summarize.
