SplitSMS

For vibe coders

SMS API built for Cursor, Bolt & AI-assisted dev

You build at the speed of prompts. SplitSMS gives you OpenAPI, copy-paste code, sandbox keys, and AI-ready docs so your agent ships OTP, notifications, and bulk SMS — without carrier negotiations or registry rabbit holes.

Works with your stack

Brand logos via Simple Icons (MIT). Bolt uses StackBlitz; v0 uses Vercel mark.

How SplitSMS helps vibe coders

Less time reading carrier PDFs. More time shipping features your users feel on their phone.

Ship in one sitting

You describe the feature in Cursor; SplitSMS gives the API shape, env vars, and working snippets so the model does not invent endpoints.

Fail cheap, learn fast

Sandbox mode means broken auth or bad payloads never burn credits. Fix integration errors from real JSON responses in request logs.

Ghana-ready by default

Sender IDs, +233 numbers, Paystack-friendly flows, and pricing in GHS — built for the market you are actually shipping to.

From prototype to production

Same API from hackathon to launch. Swap sk_test_ for sk_live_, top up wallet, and keep your code paths identical.

Vibe-coder toolkit

Everything public or one sign-in away in the developer portal.

OpenAPI + llms.txt

Point Cursor, Claude, or ChatGPT at machine-readable specs. Fewer wrong endpoints, faster first send.

OpenAPI JSON

Code generator

Pick Next.js, Express, SDK, or cURL — copy .env and starter files in one click. No boilerplate hunting.

Generate code

AI prompt library

Ready-made prompts for OTP login, webhooks, WooCommerce, Connect, and debugging — paste into your AI editor.

Browse prompts

Sandbox keys

sk_test_ keys validate every request without live SMS or credit charges. OTP verify always accepts 123456.

cURL-first docs

Every endpoint with copy-paste curl. Test from terminal before you wire UI — works in any stack.
