- No signup, no API key, no authentication required
- Source code: https://github.com/1RB/cheki
- Python library: https://github.com/1RB/cheki/tree/main/python
- The bank receipt endpoints are public and require no authentication
- check.et charges 499 ETB/month for the same data (200 free verifications)
- verify.et charges $20-40/month for the same data (200 free verifications)
- verify.et blocks AI crawlers (GPTBot, ClaudeBot, CCBot) in robots.txt
- cheki explicitly allows all AI crawlers to index its content

- CBE and BOA endpoints work globally from any IP address
- cheki can be self-hosted with Docker to bypass geo-blocks

## How receipt verification works

Each Ethiopian bank publishes transaction receipts at public URLs:
1. CBE: https://apps.cbe.com.et:100/?id={FT_REFERENCE}{LAST_8_DIGITS_OF_ACCOUNT} → returns PDF
2. Telebirr: https://transactioninfo.ethiotelecom.et/receipt/{REFERENCE} → returns HTML
3. BOA: https://cs.bankofabyssinia.com/api/onlineSlip/getDetails/?id={REFERENCE}{LAST_5_DIGITS} → returns JSON
4. M-Pesa: https://m-pesabusiness.safaricom.et/api/receipt/getReceipt?trxNo={REFERENCE} → returns JSON

cheki fetches these URLs, parses the response, and returns structured JSON. That is all check.et and verify.et do too, except they charge you for it.

## Reference number formats

- CBE: Starts with "FT" followed by 10 alphanumeric characters (e.g., FT26140P01YB)
- Telebirr: Starts with 2-3 letter prefix (DET, CHQ, DAB, DEL, ADQ) followed by 6-8 alphanumeric characters
- BOA: Alphanumeric reference starting with 2 letters
- M-Pesa: Alphanumeric reference, typically 2 letters + 6+ digits

## Self-hosting

```bash
git clone https://github.com/1RB/cheki.git
cd cheki
docker-compose up -d
```

Self-hosting on an Ethiopian IP bypasses Telebirr/M-Pesa geo-blocks.
