Plans include Free Plan at free, billed monthly, with 100 requests monthly; Starter Plan at $19.99 a month; and Pro Plan at $149.99 a month. APILayer targets individual developers and enterprise teams in fintech, e-commerce and SaaS.

Emailable verifies email addresses for cleaner mailing lists and better deliverability. Users can upload lists in bulk, customize exports, and view reports, or add a customizable widget that checks addresses in HTML forms as they are entered. Deliverability tools include inbox placement reports, blacklist monitoring, and checks for DMARC, SPF, and DKIM errors. Verification examines syntax, domains, and SMTP, and identifies disposable, accept-all, free, and role-based addresses among other risks. An HTTP API and client libraries for Node.js, Ruby, and Python support developer integrations, while the service lists connections with more than 50 apps. New accounts receive 250 free credits. The monthly subscription is $32.30 per month for 5,000 credits; pay-as-you-go costs $38 once for 5,000 credits. Credits never expire and are refunded for unknown results and duplicates after list verification. Usage is one credit per verification, 100 per inbox report, and five per blacklist check. Emailable states SOC 2 Type II, GDPR, and CCPA compliance, ISO 27001-certified data centers, 24/7 support, and at least 99.99% availability.
