Marqeta API
Marqeta is API-first: the Core REST API at /v3 is the whole product, with a three-click self-serve sandbox. Production access runs through an MSA with usage-based pricing plus sponsor-bank approval that adds weeks. Rate limits are unpublished and negotiated per contract.

Marqeta scores A on the API Report Card. Marqeta is API-first: the Core REST API at /v3 is the whole product, with a three-click self-serve sandbox. Production access runs through an MSA with usage-based pricing plus sponsor-bank approval that adds weeks. Rate limits are unpublished and negotiated per contract.
Marqeta has a workable official integration path. Most engineering teams can build against it directly. Open API: self-serve, documented, with SDKs
Marqeta is a publicly traded (NASDAQ: MQ) modern card issuing platform and issuer processor that lets fintechs, banks, and enterprises issue and manage physical, virtual and tokenized payment cards (debit, prepaid, credit, and flexible credentials) through open REST APIs.
Vertical: Financial Services (issuer processing / embedded card issuing / banking-as-a-service infrastructure). Card issuing: Create card products (Visa/MC/Discover, debit/credit/prepaid/flexible credentials), issue physical cards via fulfillment partners, or instant-issue virtual cards via API in milliseconds for single-use BNPL, AP, or push-to-card use cases..
Moderate-to-high within fintech / embedded-cards. Marqeta is not as universally embedded as Stripe (which is in nearly every SaaS stack), but within the specific subset of companies issuing their own cards, Marqeta is the dominant modern processor.
Marqeta is an issuer processor, it sits in the most sensitive part of the card-payments stack and stores or processes some of the most regulated data in financial services on behalf of its customers.
Founded 2010.
Limited first-party SDK coverage compared to Stripe, most customers hand-roll HTTP or generate clients, which slows initial integration. Pagination is offset-based rather than cursor-based, which is slower and less reliable at scale and inconsistent with modern fintech APIs. Full sourced list under Sources below.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
