# Pingram (slim)

> Pingram, formerly NotificationAPI, is a hosted messaging API that sends email and SMS and receives replies by webhook. Agents reach it through a REST API, seven server SDKs, a CLI and a hosted MCP server.

Assessment: Email and SMS go out through one REST call with built-in delivery, per-message prices are public and the free tier needs no card. No rate limits or idempotency keys were found in the reviewed documentation, and the MCP connector acts with the signed-in user's whole account.

## Before you call it

1. Use the API host for the account's region. The key and region (`us`, `eu` or `ca`) come from the API Keys page in the dashboard
2. Keep the `trackingId` from each send and check Logs before retrying. No idempotency key was found, so a blind retry can send twice
3. Pass `accountId` on MCP tools when the user belongs to several accounts. Without it the tools use the earliest account joined
4. Create broadcasts as drafts only. Pingram's own skill says a person must send a broadcast from the dashboard
5. Expect 402 when the monthly budget is spent. Unused balance does not roll over

## Connect

```bash
npm install pingram
```

```bash
curl -X POST https://api.pingram.io/email \
  -H "Authorization: Bearer $PINGRAM_API_KEY" -H "Content-Type: application/json" \
  -d '{"type":"welcome","to":"user@example.com","subject":"Welcome","html":"<p>Hello</p>"}'
```
