Platform

Six APIs. One key.
Zero switching costs.

Every service you'd otherwise stitch together from separate vendors — consolidated under a single dashboard and billing account.

01 — AUTH

Authentication

OAuth 2.0, magic links, passkeys, and MFA. Drop-in embeds for React, Vue, and plain HTML.

02 — PAY

Payments

Accept cards, UPI, and wallets in 180 countries. Smart retry and built-in fraud scoring.

03 — MSG

Messaging

Email, SMS, and push from one endpoint. Template management with A/B testing baked in.

04 — DATA

Data Enrichment

Turn an email into a full company profile. Firmographics, social, and tech-stack signals.

05 — GEO

Geo & IP Lookup

Resolve any IP to country, city, timezone, and currency. Edge-cached under 5ms globally.

06 — LOG

Audit Logging

Tamper-proof event log for every API call. Stream to S3, Datadog, or our hosted viewer.
