API Ninjas

@api-ninjas check if support@tempmail.io is a disposable email address before I add it to our beta tester list

The Check Disposable Email tool reports that support@tempmail.io is flagged as a disposable email provider. This domain is commonly used for temporary inboxes that expire after a short period. In this illustrative example, the MCP would return a boolean flag indicating the email's disposable status, helping you filter out addresses unlikely to receive long-term communications.

This example highlights the MCP's email validation capability, useful for cleaning signup forms or CRM imports. Requires an API Ninjas API key with sufficient quota. The tool checks against a known list of disposable providers but cannot detect all temporary email services or newly launched domains.

@api-ninjas what are the DNS records for example.com? I need to verify the MX and TXT entries for our domain migration checklist.

The DNS Lookup tool retrieves current records for example.com. In this illustrative response, you'd see MX records pointing to mail servers (e.g., mail.example.com with priority 10), TXT records including SPF and DKIM entries for email authentication, and A records mapping the domain to its IP address. This snapshot helps confirm your DNS configuration matches migration requirements before cutover.

This example demonstrates a read-heavy diagnostic use case common in DevOps workflows. The tool performs a live DNS query, so results reflect real-time state. Be aware that DNS propagation delays mean recent changes may not appear immediately, and the API key must have access to the DNS Lookup endpoint.

@api-ninjas pull the latest earnings call transcript for AAPL Q1 2024 and summarize the key product announcements and revenue guidance mentioned by the CFO

The Earnings Call Transcript tool fetches the full text of Apple's Q1 2024 earnings call. In this illustrative example, the AI would parse the transcript and extract highlights such as iPhone revenue growth of 6% year-over-year, services segment reaching $23 billion, and forward guidance indicating cautious optimism for Q2 amid supply chain stabilization. The summary condenses a multi-page document into actionable insights for investment research or competitive analysis.

This example pairs the MCP's data retrieval with the AI's synthesis capability, turning raw transcripts into digestible summaries. Transcripts are only available after earnings are released, not for upcoming calls. API rate limits may apply if querying multiple tickers in quick succession, so batch requests carefully during earnings season.

When API Ninjas beats a full fraud suite for small e-commerce

A 6-person DTC brand processes 200 orders a day and sees 8% of signups bounce from disposable emails. They don't need Stripe Radar's $0.05-per-transaction tier yet. API Ninjas gives them BIN lookup to flag prepaid cards and disposable email checks to block throwaway addresses—both in one workspace, no separate vendor contracts. The team runs these checks in Switchy during order review, tagging suspicious transactions before they hit fulfillment. This works until you cross 1,000 orders a day or need real-time scoring at checkout; then you graduate to a dedicated fraud API. For pre-scale validation where a human still eyeballs each flag, API Ninjas keeps fraud tooling inside your existing workflow without adding another SaaS bill.

Why this MCP is overkill for pitch prep but perfect for diligence

A 3-person startup is building their Series A target list and needs to know which VCs just raised new funds. They don't need Bloomberg terminals. API Ninjas' earnings calendar and ETF info tools let them pull public fund filings and check which firms are deploying capital this quarter—all from the same Switchy workspace where they're drafting outreach emails. The crypto and commodity price tools are dead weight here, but the DNS lookup catches typos in investor domain research, and the transcript tool helps them prep for partner calls by reading what those VCs asked portfolio companies last quarter. This breaks down if you need historical data older than 2 years or want to automate daily alerts. For one-time research sprints where a founder is manually connecting dots, API Ninjas consolidates 4 separate data subscriptions into 18 API calls you actually control.

When disposable email checks belong in your support workflow

A 5-person customer success team onboards 30 new accounts a month and loses 12% to fake signups that churn in week one. They're not engineers, so building a validation pipeline is off the table. API Ninjas' disposable email check runs inside Switchy when a CSM reviews a new signup—one click to flag throwaway domains before they send onboarding docs or provision seats. The BIN lookup tool adds a second layer: if the trial card is prepaid, the CSM knows to ask for a company card before investing time in a demo. This stops working when you hit 200 signups a month and need automated pre-provisioning checks; then you need Clearbit or a Zapier integration. For teams where a human still touches every new account and you want validation without writing code, API Ninjas turns fraud prevention into a CSM task, not an engineering sprint.
