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 5 API contracts indexed on the APIs.io network, including Payments API (v1, deprecated), Account API, Exchange API, and 2 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 and 1 Spectral governance ruleset.

Capitalist’s developer surface includes authentication, documentation, API reference, support, engineering blog, signup flow, pricing, and 25 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 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/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too
Pagination +5 pts — share of collection GETs (an array, or one wrapped in data/items/results ...) that declare a page/limit/offset/cursor parameter, a Link header or a next/cursor field; na with no collection GETs

5 more unmet checks in the Agent Readiness table above.
