tx-verify 1.0.2

Transaction Verification API — Python library for verifying Ethiopian payment transactions (CBE, Telebirr, Dashen, Abyssinia, CBE Birr, M-Pesa).

tx-verify

Python library for verifying Ethiopian payment transactions across multiple providers: CBE, Telebirr, Dashen Bank, Bank of Abyssinia, CBE Birr, and M-Pesa.

Each verifier fetches the official receipt from the provider (PDF or HTML), parses it, and returns typed result objects. No headless browser is bundled — PDFs are parsed with pypdf and HTML with BeautifulSoup — so it runs anywhere Python does.

Quick Start

import asyncio
from tx_verify import verify_telebirr, verify_cbe

async def main():
    # --- Telebirr ---
    receipt = await verify_telebirr("CE12345678")
    if receipt:
        print(receipt.payer_name, receipt.settled_amount)

    # --- CBE ---
    result = await verify_cbe("FT23062669JJ", account_suffix="12345678")
    if result.success:
        print(f"Paid {result.amount} ETB to {result.receiver}")

asyncio.run(main())

Provider Reference

CBE — Commercial Bank of Ethiopia

CBE references are 12 characters starting with FT. You must supply the last 8 digits of the account number as a suffix. The bank returns a PDF that is fetched and parsed automatically.

from tx_verify import verify_cbe

result = await verify_cbe("FT23062669JJ", "12345678")
# result.success      → bool
# result.payer        → str | None
# result.receiver     → str | None
# result.amount       → float | None
# result.date         → datetime | None
# result.reference    → str | None
# result.reason       → str | None
# result.error        → str | None

Telebirr

Telebirr references are 10-character alphanumeric codes. The library scrapes the public Ethio Telecom receipt page.

from tx_verify import verify_telebirr

receipt = await verify_telebirr("CE12345678")
# receipt.payer_name, receipt.settled_amount, receipt.total_paid_amount, …

Dashen Bank

Dashen references are 16-digit numbers starting with 3 digits (e.g. 1234567890123456). The verifier fetches a PDF with built-in retry logic (up to 5 attempts).

from tx_verify import verify_dashen

result = await verify_dashen("1234567890123456")
# result.sender_name, result.transaction_amount, result.total, …

Bank of Abyssinia

Abyssinia references are also 12 characters starting with FT, but the suffix is the last 5 digits of the account number. The bank returns JSON rather than a PDF.

from tx_verify import verify_abyssinia

result = await verify_abyssinia("FT23062669JJ", "90172")
# result.payer, result.amount, result.date, …

CBE Birr

CBE Birr receipts are 10-character alphanumeric codes. You also need the wallet phone number in local Ethiopian format (e.g. 0911234567).

from tx_verify import verify_cbe_birr

result = await verify_cbe_birr("AB1234CD56", "0911234567")
# result.customer_name, result.amount, result.paid_amount, …

M-Pesa

M-Pesa references are 10-character alphanumeric codes. The verifier hits the Safaricom primary API.

from tx_verify import verify_mpesa

result = await verify_mpesa("UE20VG1GS8")
# result.payer_name, result.amount, result.service_fee, result.vat, …

Image verification (Mistral Vision)

Upload a receipt image (JPEG/PNG) and Mistral Vision AI will detect whether it is a CBE or Telebirr receipt, extract the reference, and optionally verify it automatically.

from tx_verify import verify_image

with open("receipt.jpg", "rb") as f:
    image_bytes = f.read()

# Detect only
info = await verify_image(image_bytes, auto_verify=False)
print(info.type, info.reference, info.forward_to)

# Auto-verify (account_suffix required for CBE)
info = await verify_image(
    image_bytes,
    auto_verify=True,
    account_suffix="12345678",
)
print(info.verified, info.details)

Requires MISTRAL_API_KEY environment variable and the mistralai package (installed automatically).

Universal — auto-route by reference format

Hand any reference to verify_universal() and it routes to the correct provider based on length and prefix:

Reference format	Routed to
16 digits starting with 3	Dashen Bank
12 chars starting with FT + 8-digit suffix	CBE
12 chars starting with FT + 5-digit suffix	Bank of Abyssinia
10 chars + phone_number	CBE Birr
10 chars (no phone)	Telebirr

from tx_verify import verify_universal

result = await verify_universal("CE12345678")
print(result.success, result.data, result.error)

---

Proxy Support

All receipt verifiers accept an explicit proxies argument. Environment variables are never read automatically — you must pass the proxy yourself.

Supported schemes:

Scheme	Description
http	Plain HTTP forward proxy
https	HTTPS proxy (CONNECT tunnel)
socks4	SOCKS4 proxy
socks5	SOCKS5 proxy (client resolves DNS)
socks5h	SOCKS5 proxy (proxy resolves DNS)

Authentication is embedded in the URL:

# Single global proxy
proxies = "http://user:[e-mail]:8080"

# Per-scheme mapping
proxies = {
    "http://":  "http://proxy.example.com:8080",
    "https://": "socks5://localhost:1080",
}

Pass it to any verifier:

from tx_verify import verify_telebirr, verify_cbe, verify_mpesa

# Telebirr through an HTTP proxy
receipt = await verify_telebirr("CE12345678", proxies="http://proxy:8080")

# CBE through SOCKS5
result = await verify_cbe("FT23062669JJ", "12345678", proxies="socks5://127.0.0.1:1080")

# M-Pesa with per-scheme mapping
result = await verify_mpesa("UE20VG1GS8", proxies={
    "http://": "http://proxy:8080",
    "https://": "socks5h://proxy:1080",
})

verify_universal and verify_image also forward proxies to the underlying provider automatically.

SOCKS tip: socks5h:// tells the proxy server to resolve hostnames, which is useful when the client cannot reach DNS directly.

Error Handling

All verifiers return result objects rather than raising for expected failures (network errors, missing receipts, parsing failures). Inspect result.success and result.error.

Telebirr may raise TelebirrVerificationError when a proxy returns an explicit error message. Catch it if you want to show the user a friendly message:

from tx_verify import TelebirrVerificationError, verify_telebirr

try:
    receipt = await verify_telebirr("INVALID_REF")
except TelebirrVerificationError as exc:
    print(f"Telebirr error: {exc}")
    if exc.details:
        print(f"Details: {exc.details}")

The library also provides a generic error handler for wrapping database or internal errors:

from tx_verify.utils.error_handler import AppError, ErrorType

---

Environment Variables

Variable	Purpose
MISTRAL_API_KEY	Required for verify_image()
LOG_LEVEL	DEBUG or INFO (default INFO)
