Cielo is one of the largest Brazilian card acquirers and a publicly traded company (B3:CIEL3), originally formed as a joint venture between Banco Bradesco and Banco do Brasil. The company processes credit, debit, Pix, QR Code, and boleto transactions for hundreds of thousands of merchants across Brazil, providing both in-person acquiring through its family of Cielo Smart (formerly LIO) Android POS terminals and Tap on Phone, and online payment processing through its e-Commerce API, Checkout, Payment Links, and Braspag gateway. Cielo exposes a broad developer surface through developercielo.github.io and the newer docs.cielo.com.br portal, including APIs for sales, queries, tokenization, 3DS 2.2 authentication, Pix with mTLS, chargeback management, refunds, reconciliation (Conciliador), and merchant promotions, along with open-source SDKs in Python, PHP, Java, C#, Kotlin, Swift, and Dart published from the DeveloperCielo GitHub organization.
Cielo is listed with 13 APIs on the APIs.io network. Tagged areas include Payments, Acquiring, Fintech, Brazil, and Point-of-Sale.
Cielo’s developer surface includes developer portal, documentation, developer console, signup flow, pricing, getting-started guide, API reference, and 32 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Payments regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/cielo: open an issue to ask a question, or submit a pull request to add artifacts.

Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market:
its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted:
not part of the Kin Score or agent readiness.
Registered MCP server and declares compatibility are report only — not weighted.
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

SoftPOS / Tap on Phone
Micro-entrepreneurs and field sales reps accept contactless card payments directly on their NFC-capable smartphones via Cielo Tap, without renting a dedicated POS device.
Online Card Acquiring
E-commerce platforms use the Cielo e-Commerce API (API 3.0) to authorize, capture, void, and tokenize card transactions on Visa, Mastercard, Elo, Amex, Hipercard, and more.
Hosted Checkout and Payment Links
Merchants with limited engineering capacity use Cielo Checkout or Payment Links to accept payments via shareable URLs on WhatsApp, Instagram, and SMS without building a storefront.
Pix Charges and Refunds
Platforms generate immediate and recurring Pix charges, receive real-time settlement events via webhooks, and issue refunds through the Pix API with mTLS-secured access.
3DS 2.2 Authentication
Online merchants reduce chargeback exposure by routing card-not-present transactions through Cielo's Braspag MPI for liability-shifted authentication.
Dispute and Refund Management
Operations teams query, accept, refuse, and document chargebacks and process refunds in bulk via dedicated APIs with letter-generation and evidence-download endpoints.
Financial Reconciliation
Finance teams reconcile sales, fees, and settlement events using the Cielo Conciliador API (F360) to pull card and title installments, bank statements, and parameterised reports.
Recurring Payments and Tokenization
Subscription businesses save card-on-file via Cielo's tokenization endpoints and bill on a recurring schedule with Zero Auth validation between charges.
