Thredd
Thredd (formerly Global Processing Services / GPS) is a London-headquartered issuer-processor and next-generation payments technology company, founded in 2007, rebranded to Thredd in 2023, and backed by Advent International. It provides card issuing and issuer processing for fintechs, neobanks, banking-as-a-service platforms, and program managers across Mastercard, Visa, and Discover, spanning 40+ countries, with real-time transaction authorization (External Host Interface / EHI), digital-wallet tokenization (Apple Pay, Google Pay), 3-D Secure / strong customer authentication, card controls, and fraud / scam detection. Its home market is the United Kingdom. Thredd ships a genuine public developer surface: a self-serve Developer Portal (devportal.thredd.com) that grants a sandbox client id and secret, an API Hub REST API at api.thredd.com, and a ReadMe-hosted API reference (cardsapidocs.thredd.com) documenting roughly 129 endpoints across more than a dozen product OpenAPI definitions (core cards, transactions, credit, custom PAN, card limits, card controls, digital wallets, 3DS, ACH, open banking, alias directory, and web services). Authentication is FAPI-grade OAuth2 client-credentials using private_key_jwt client assertions over mutual TLS, brokered by Cloudentity with Raidiam Connect acting as the certificate authority; webhooks and event subscriptions are supported. The underlying OpenAPI files render only through the hub and are not anonymously downloadable.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Thredd the way a machine reads it — 14 machine-readable artifacts across 10 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Thredd scores 41.4/100 (developing), with a separate agent-readiness read of 26/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.
Put this on your own site. The badge is drawn live from Thredd's current Kin Score — paste it once and it updates itself every time the score is recomputed. It follows your visitor's light or dark setting, and it links back here so anyone who sees it can read the full breakdown.

How we profile Thredd
Each block below is one kind of artifact we hold for Thredd. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 10
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Thredd Cards API
Create, retrieve, update, renew, replace, and convert physical and virtual cards; manage card status, cardholder details, card images, encrypted card data, and bulk card creatio...
Thredd Card Transactions API
Retrieve card transactions and transaction history, including load / unload operations and balances, for cards managed on the Thredd platform.
Thredd Card Controls & Limits API
List and update card control groups, manage merchant allow / disallow lists and card acceptors, and configure card spend limits at the product level.
Thredd 3-D Secure (SCA) API
Create, list, update, and delete 3-D Secure credentials and configuration for strong customer authentication (SCA) on issued cards.
Thredd PIN & CVV Management API
Set, retrieve, and unblock cardholder PINs, and retrieve and unblock CVV2 values and their status, over the Thredd API Hub.
Thredd Digital Wallets API
Enroll and provision cards into Apple Pay and Google Pay, generate wallet web-provisioning tokens, and manage payment-instrument tokenization for digital wallets.
Thredd Webhooks & Event Subscriptions API
Create and manage webhooks and event subscriptions to receive asynchronous notifications of card, transaction, and account events from the Thredd platform.
Thredd Credit API
Credit account and credit-program endpoints for managing credit overviews and related credit issuing capabilities on the Thredd platform.
Thredd Custom PAN API
Create customisable card numbers (custom PAN) so programs can define specific primary account number patterns for their issued cards.
Thredd Accounts API
Account-level endpoints supporting account records and money-movement flows (including ACH / micro-deposit verification) on the Thredd platform.

Event Specifications 1
Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.
AsyncAPI definitions for this provider's event-driven and streaming APIs.

ASYNCAPISecurity Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Scopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.

This is an independent, third-party profile of Thredd, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
