# SMS for startups, indie developers and side projects

> SMS for startups and indie developers: sign up with an email, build against a free test key, fund a few dollars in crypto, pay per message with no contract, no monthly fee and no KYC.

For a startup or a side project, SMSMeteor removes the steps that usually sit between an idea and a delivered text: there is no business verification, no minimum commitment and no monthly fee. Every account has an `sk_test_` key that validates and prices requests without sending, so the integration can be finished before any money moves; going live means switching keys and funding the balance in one of seven cryptocurrencies.

## Recommended settings

- To start: Email address and password
- Before paying: `sk_test_` key: validates, prices, never sends
- Commitment: None: no contract, no monthly fee
- API: Six REST endpoints, OpenAPI 3.1
- Limits: 50 requests per second per key; 1,000 messages per API request
- Reach: 228 destinations from one integration

## Steps

1. Create the account: An email address and a password. No company name, no documents, no call.
2. Build on the test key: Same validation, prices and webhook events as production, with status test and no billing.
3. Fund a small balance: USDT on a low-fee network is the cheapest way to move a modest amount. Credit never expires.
4. Switch keys and ship: Replace the test key with a live one. Nothing else in your code changes.

## What you skip

Most messaging vendors were built for enterprises: identity and business verification, sender registration programmes, a sandbox limited to verified numbers, support behind a paid plan. For a product that is three people and a repository, each of those is a week. Here the path is an email address, a test key and a rate card you can read before you sign up.

What you still owe the world is the content rule: consent for marketing, no impersonation, no spam. That is the whole of the compliance conversation.

## An API that survives production

The API is small on purpose: send, batch, retrieve, list, rates, balance. It has the properties that matter when things go wrong: idempotency keys so retries are safe, stable error codes, rate-limit headers, signed webhooks with retries and replays, and a request id on every response. The OpenAPI file generates a typed client in any language, so there is no SDK to keep updated.

## Sample message

From MYAPP: "MyApp: your login code is 204 913. It expires in 10 minutes."

```bash
# 1. Build against the test key: validates and prices, never sends
curl https://api.smsmeteor.com/v1/messages \
  -H "Authorization: Bearer sk_test_..." \
  -H "Idempotency-Key: signup-1042-otp-1" \
  -d to="+14155550142" -d from="MYAPP" \
  -d text="MyApp: your login code is 204 913."

# -> { "id": "msg_...", "status": "test", "segments": 1, "price": "0.0084" }

# 2. Go live: same request with sk_live_...
```

## Questions

**Can I try the API for free?** Yes. The test key validates requests, returns real prices and segment counts and fires test webhook events, without sending or billing. Live messages need a funded balance.

**Is there a monthly fee or a minimum spend?** No. You pay per message at the published rate. An unused balance stays on the account indefinitely.

**Do I need a registered company?** No. Individuals, sole traders and unincorporated projects can open an account with an email address.

**Is there an SDK?** There is no SDK to install: the API is six endpoints of plain JSON. An OpenAPI 3.1 file generates a typed client in TypeScript, Python, Java and others, and samples exist in six languages.

**How much do 1,000 messages cost?** It depends on the destination: $8.40 to the United States, $13.00 to the United Kingdom, $25.60 to India at today's rates.

**What happens when my project grows?** Nothing changes: the same rate applies from the first message to the millionth, batches take 1,000 messages per API request, and there is no tier to negotiate.
