Capitalist

Capitalist is a payment platform that lets businesses make mass payouts and receive money across multiple payment systems and cryptocurrencies without having to open separate accounts with each. The Capitalist Integration API automates bulk payouts to cards, bank transfers, mobile operators, fast payment systems, e-wallets and cryptocurrencies, converts between fiat and digital-asset balances, reads exchange rates and account balances, retrieves transaction and merchant-order history, and runs end-user KYC — for fintech, affiliate-network, and marketplace use cases operating across the CIS region and globally.

Capitalist publishes 2 APIs on the APIs.io network, including Payments API (v1, deprecated), and 1 more. Tagged areas include Bulk Payouts, Cryptocurrency, Finance, Mass Payments, and Payment Platform.

The Capitalist catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Capitalist’s developer surface includes authentication, documentation, API reference, support, engineering blog, signup flow, pricing, and 24 more developer resources.

scored 2026-09-08 · rubric v0.20.0
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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% 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/capitalist: open an issue to ask a question, or submit a pull request to add artifacts.

  description: The current Capitalist API — published as the "Integration API" — enables programmatic mass payouts, currency
    and digital-asset conversion, and balance, transaction and merchant-order reporting across Capitalist's supported payment
    systems. It is a JSON-over-HTTPS REST surface at https://api2.capitalist.net that creates and tracks outbound payouts
    across roughly 45 payment channels (cards, bank transfers, mobile operators, fast payment systems, e-wallets and cryptocurrencies),
    issues ephemeral cryptocurrency deposit addresses, and runs end-user KYC. Every request carries three headers — API-Key,
    X-Request-Timestamp and a SHA-256 signature over the timestamp, the raw body and the API secret — and payment outcomes
    are delivered to a per-request callbackUrl signed the same way. It is designed for businesses that need to pay large numbers
    of recipients (affiliates, freelancers, publishers) without maintaining separate accounts in each underlying payment system.
