Best alternatives to apiCEP in 2026
Imagine getting a bank transfer receipt from a stranger online — a screenshot, a photo, a PDF — and having to decide in seconds whether it's real or a clever fake. That's the problem apiCEP solves for businesses across Mexico that get paid by bank transfer instead of a credit card. It works a bit like a notary for digital payments: you hand it a receipt, and within about ten seconds it tells you whether the money actually moved, checking directly against Mexico's central bank records and catching doctored amounts, made-up transactions, and receipts that were never real to begin with. Technically, apiCEP is a REST API built around Mexico's CEP (Comprobante Electrónico de Pago) system, the official proof-of-payment record maintained by Banxico. Clients submit a receipt image or PDF; the service applies OCR to extract the transaction's key fields (amount, date, sender/receiver bank details, tracking key) and cross-references them against Banxico's SPEI records to confirm the transfer is genuine rather than just well-formatted. Successful lookups return a confirmed CEP document in machine-readable XML plus a downloadable PDF that businesses can archive for compliance or dispute resolution. It's aimed at high-volume transfer-based checkouts — e-commerce, fintech neobanks, PropTech, WhatsApp-based sales, ticketing platforms — where manually eyeballing receipts doesn't scale.
