About
Postcoder is an API from Allies Computing that gives developers a single endpoint for verifying and validating customer contact data at the point of entry. Used across sectors from healthcare to retail, it's built to drop into checkout, onboarding, and account creation flows with minimal friction.
What's included:
Address lookup – Postcode, partial address, or coordinate-based search across Royal Mail PAF, Ordnance Survey AddressBase, and 249 countries worldwide.
Bank validation – Real-time sort code and account number verification, with branch data and direct debit eligibility returned in the response.
Email validation – Domain and formatting checks with disposable address detection.
Mobile validation – Live network status checks across 200+ countries.
OTP verification – SMS-based one-time password delivery.
Clear documentation, multi-language sample code, and a straightforward REST structure mean integration is quick. 30 day free trial with no credit card required.

About
emailfinder.dev is a real-time email discovery API built for developers, sales teams, and recruiters who need verified professional email addresses without the overhead of expensive subscriptions or stale databases.
Every lookup performs live SMTP verification at the moment of the request. There is no pre-built database. When you search for an email, we check it against the actual mail server in real time. This means you get current, deliverable addresses — not months-old data that bounces.
Four endpoints cover every use case. Person lookup takes a name and company domain and returns a verified email. Company lookup takes a domain and returns up to 20 verified addresses at that organization. LinkedIn lookup extracts the email behind any LinkedIn profile URL. Decision maker lookup finds the right person by role — CEO, CTO, Head of Marketing, VP Sales, and more.
The API is simple. Standard REST with GET requests and Bearer token authentication.
