All projects on Base matching “http headers”

Audit a URL's HTTP security headers over a single body-free (HEAD) request. Grades Strict-Transport-Security, Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy and Permissions-Policy, flags information-leak headers (Server, X-Powered-By), and returns the parsed values plus advisory warnings. Clean JSON for security and pentest automation.

Sends a request to a web address you provide and reports back everything the server said in response: the status code, all the response headers, how many times it got redirected, and how long the whole thing took.

Fetch a site's robots.txt and evaluate crawl permissions: given a URL (plus optional extra paths) and a user-agent, return whether each path is allowed or disallowed, the rule that matched, the user-agent group, the crawl-delay and any declared sitemaps. Implements the Robots Exclusion Protocol (RFC 9309) with longest-match-wins, Allow-over-Disallow tie-breaking and * / $ wildcards.

Pay $0.01 USDC to make an outbound HTTP request through the proxy. Supports all standard HTTP methods, custom headers (including auth), and JSON or raw bodies. Responses are returned as text or base64-encoded binary. Max response size 10 MB, timeout 30s. Each request performs one upstream fetch and returns the final URL plus response metadata.

Detect the technologies a website runs — CMS, ecommerce platform, analytics, marketing/CRM, JS framework, hosting/CDN, chat and payments — straight from its public HTML and HTTP headers. No browser, no proxies, no login. Built for sales targeting and competitive research.

Return RDAP registration, subdomains, and HTTP headers for a domain.

Public domain DNS, mail configuration and HTTP security headers

A2A, MCP & HTTP 402 Endpoint SLA Compliance Auditor (/v1/x402-audit) — Audits any remote agent or MCP URL for JSON-RPC compliance, latency SLA, OpenAPI schema, and HTTP 402 settlement headers. (https://preflight.agentdiet.dev/v1/preflight/certify)

Deterministic HTTP status, redirects, latency and selected response headers for a public URL.

Full-domain intelligence report in one call: complete DNS sweep (A/AAAA/MX/NS/TXT/SOA/CNAME), RDAP registration data (registrar, dates, statuses), DNSSEC presence, mail posture summary (SPF/DMARC/DKIM selectors), TLS certificate snapshot (issuer, expiry, protocol), Certificate Transparency subdomain census, and HTTP probe (status, redirects, https enforcement, server header) — each section scored,

Fetch a public https CSV URL and parse it into headers + rows ($0.005 USDC via x402). https only — http, file, data, localhost, and private IPs are rejected. Caps: 1 MB body, ~10s timeout, max 5 redirects, max 5000 data rows (truncated with warning). Optional has_header (default true). Returns JSON { url, final_url, content_type, headers, rows, row_count, warnings }.

Schedules a delayed HTTP callback: give a public URL, an optional JSON body, optional headers and a delay of 60 seconds to 7 days (or an absolute time), and this host calls the URL at that time (POST when a body was given, otherwise GET), with one retry and a 10-second timeout. GET /later/<id> reports whether it fired and the status code the callee answered. A request that is refused is not charge

Domain OSINT, TLS Certificate & Security Headers Recon (/v1/domain-osint) — Inspects live IPv4/IPv6 DNS resolution, TLS certificate issuer/expiry, and HTTP security grade. (https://domain-osint.agentdiet.dev/v1/domain-osint)

Fetches a public http(s) URL (GET, up to 5 redirects, 10s timeout, body never read) and grades its security headers A+ to F. Returns score, present and missing headers, per-header findings with copy-paste fix values, and cookie flag issues.

Send an HTTP request to any URL from our servers and receive the full response — including the status code, all response headers, and the body content. Supports GET, POST, PUT, PATCH, DELETE, and HEAD. Automatically follows up to 3 redirects. Useful for testing endpoints, verifying servers are responding correctly, debugging redirect chains, or fetching raw data without needing a local setup.

Audit a public HTTPS x402 API without payment: HTTP 402 challenge metadata, Bazaar and well-known discovery, OpenAPI 3.1 operation schemas and payment declarations, redirects, latency, and security headers.

HTTP endpoint health audit for one URL: status and redirect chain, latency p50/p95 over repeated samples, TLS certificate expiry and issuer, the response headers that matter, and a list of detected anomalies (missing HSTS/CSP/X-Content-Type-Options, expiring cert, weak TLS, CORS wildcard, insecure cookies, version disclosure, slow p95, redirect loops). Private, loopback and link-local targets are

Cheapest real end-to-end test of your pay-per-call (HTTP 402) client: pay US$0.002, get back what was paid (payer, amount, network, timestamp) and the text you sent; the settlement receipt is in the PAYMENT-RESPONSE header. A free trial call returns paid_usd 0. Use it to check a wallet, a client library or a facilitator before buying something bigger.

Technical SEO audit of one page: HTTP status, redirect chain, title and meta description length, H1 count, canonical, robots meta, hreflang, Open Graph and Twitter tags, JSON-LD types, images without alt text, link counts, security headers (HSTS, CSP, X-Frame-Options), technology detection (CMS, framework, analytics, CDN) and a prioritised issue list with a 0-100 score. Static HTML only; honours r

Use ping when you need a pass/fail verdict that a URL serves expected content: expected HTTP status (default 200), a required body substring, and/or an exact match on one JSON field. One automated fetch at request time, signed receipt with per-condition results. POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header.
