# NetIntel Text Summarizer > NetIntel Text Summarizer is a paid API for AI agents from netintel-production-440c.up.railway.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-13). Summarizes a block of text into a concise summary with key points, a quality grade, compression ratio, and word counts ## Facts - Endpoint: POST https://netintel-production-440c.up.railway.app/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-text-summarizer-b479e3a9 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_IbskTcgJHX-Tin3PDC-4L 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-text-summarizer-b479e3a9 -d '' ``` Example prompt: Can you summarize this article for me and pull out the key points? Here's the text: 'Scientists at CERN have announced a major breakthrough in particle physics, detecting a new subatomic particle that could reshape our understanding of the standard model. The discovery, made after years of data analysis from the Large Hadron Collider, suggests that matter may behave differently at extremely high energy levels than previously theorized. Researchers from 40 countries collaborated on the project, marking one of the largest international scientific efforts in history.' ## When to prefer this Use this endpoint when you need a structured, graded summary of a text passage with explicit key points and compression metrics. Prefer it over generic summarization when you want a quality score and grade alongside the summary, or when operating in an x402 micropayment-enabled agentic pipeline that bills per call in USDC on Base. ## Known failure modes - Empty or missing text body returns a 400 error - Payment not included or insufficient USDC triggers a 402 Payment Required response - Extremely short input text may yield a low-quality or near-identical summary - Very large text inputs may exceed token limits and return a truncation or error response - Network timeout on the Railway-hosted service returns a 503 or connection error ## How this service works Summarize any text or web page into a concise summary plus key bullet points using Claude Haiku — accepts raw text or a URL (which it fetches and extracts), 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 (e.g. 'A'), a numeric quality score (0–100), the source label, a prose summary, a list of findings, an array of key_points, a compression_ratio (float), 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.
