# Vextorium URL Technical Inspector > Vextorium URL Technical Inspector is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-13). Performs a deep technical HTTP inspection of a URL, returning status code, redirects, timing metrics, compression, content type, cache policy, server, CDN, cookies, and all response headers including security headers. ## Facts - Endpoint: POST https://api.vextorium.com/inspeccionar-url-pago?utm_source=zero.xyz - Price: $0.003/call - Payment: x402 - Status: unknown - Last checked: 2026-10-13 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/vextorium-url-technical-inspector-5f3be618 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_0Vqj_sb_nC9B3x5GByfEk 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 vextorium-url-technical-inspector-5f3be618 -d '' ``` Example prompt: Can you do a full technical inspection of https://github.com — I want to see the HTTP status, any redirects, response time, compression, CDN, cookies, and all security headers it returns? ## When to prefer this Choose this endpoint when you need a comprehensive, single-call HTTP diagnostic covering timing, headers, security posture, CDN, compression, and cookies for a given URL — especially useful for security audits, performance troubleshooting, redirect chain analysis, or infrastructure reconnaissance. Prefer this over a simple HTTP ping when you need the full header envelope and security header checklist. ## Known failure modes - Invalid or malformed URL returns an error - Unreachable URLs (DNS failure, connection refused, timeout) may return null metrics or an error object - URLs requiring authentication may return 401/403 status with limited header data - Very slow servers may cause timeout before full response is captured - URLs that block non-browser user agents may return unexpected responses ## How this service works Technical inspection of a URL: status, redirects, time to first byte and total time, bytes, compression, content type, cache policy, server, CDN, cookies set, security headers present and all response headers. ## Output Returns a structured JSON object with: HTTP status code, number of redirects, final resolved URL, total response time in milliseconds, bytes transferred, compression type (e.g. gzip), content type, cache-control value, server name, CDN provider, ETag presence, list of cookies set, a breakdown of which security headers are present (HSTS, CSP, X-Frame-Options, Referrer-Policy, X-Content-Type-Options, Permissions-Policy, X-XSS-Protection), and the full map of all raw response headers. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method", "bodyType", "body" ], "properties": { "body": { "required": [ "url" ], "properties": { "url": { "type": "string" } } }, "type": { "type": "string", "const": "http" }, "method": { "enum": [ "POST" ], "type": "string" }, "bodyType": { "enum": [ "json", "form-data", "text" ], "type": "string" } }, "additionalProperties": false }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "type": "string" }, "example": { "type": [ "object", "null" ], "properties": { "cdn": {}, "etag": { "type": [ "boolean", "null" ] }, "codigo": { "type": [ "number", "null" ] }, "cookies": { "type": [ "array", "null" ], "items": { "type": [ "null", "string" ] } }, "servidor": { "type": [ "string", "null" ] }, "cabeceras": { "type": [ "object", "null" ], "properties": { "date": { "type": [ "string", "null" ] }, "etag": { "type": [ "string", "null" ] }, "vary": { "type": [ "string", "null" ] }, "server": { "type": [ "string", "null" ] }, "set-cookie": { "type": [ "string", "null" ] }, "content-type": { "type": [ "string", "null" ] }, "accept-ranges": { "type": [ "string", "null" ] }, "cache-control": { "type": [ "string", "null" ] }, "referrer-policy": { "type": [ "string", "null" ] }, "x-frame-options": { "type": [ "string", "null" ] }, "c … (truncated) ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "cdn": null, "etag": true, "codigo": 200, "cookies": [ "_gh_sess", "_octo" ], "servidor": "github.com", "cabeceras": { "date": "Fri, 02 Oct 2026 16:30:56 GMT", "etag": "W/\"f5927ebefa94d7b7c704363775d026a9\"", "vary": "X-PJAX, X-PJAX-Container, Turbo-Visit, Turbo-Frame, X-Requested-With, X-GitHub-Client-Version, Accept-Language, Sec-Fetch-Site,Accept-Encoding, Accept, X-Requested-With", "server": "github.com", "set-cookie": "_gh_sess=FtpXJflRwzWWLBj5ITkvuGi7%2F3dD0cM4CdYBXQGU9NgjhOFskxjkkzfFm1edKFFzojtmR8BZf%2BU31znZqmyKL54V%2FTF603fhH7QShHG38nZPftF7nviYfq5HkAVkXBml%2BFDu59%2F3y9QT7qY3ev1oyg9U6Fa8D48ptba%2BObanKOLVj7Q8CRvDJ2p837UeUzR1iMCSA2dDwvexx5%2FL%2FKQHDzXYpXHfhZ9kNcQhJ4dNnMyxObA79XphdhFnsU5xSY3bzaqsHyAwwlmVeHTj%2F…", "content-type": "text/html;
