Telleroo
Telleroo is a UK bulk payments platform that automates supplier and payroll payments for businesses, accountants and bookkeepers. It provisions a ring-fenced e-money wallet in the customer's name and sends bulk Faster Payments 24/7 (including bank holidays), plus international payments in 25+ currencies over SEPA, ACH and SWIFT. Built-in fraud controls include Confirmation of Payee, new/updated payee alerts and multi-level approval workflows, and it integrates with accounting and payroll software such as Xero, QuickBooks, Employment Hero and Staffology. Telleroo exposes two RESTful APIs: a Business API (v1, token auth) for automating outbound payments from your own account, and a Partner/Embedded Payments API (v3, OAuth 2.0) for building pay runs into your own platform on behalf of client companies. Both support idempotent requests, real-time webhooks and a dedicated sandbox environment.
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 Telleroo the way a machine reads it — 6 machine-readable artifacts across 2 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 — Telleroo scores 47.7/100 (developing), with a separate agent-readiness read of 23/100 (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.

How we profile Telleroo
Each block below is one kind of artifact we hold for Telleroo. 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 2
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.
Telleroo Business API
RESTful API (v1) to automate outbound payments from your own Telleroo account: manage recipients, query accounts and transactions, and create bank transfers (to a saved recipien...
Telleroo Partner API
RESTful Embedded Payments API (v3) to build Telleroo into your own platform: authorize against client companies over OAuth 2.0 (authorization code, scope "create"), enumerate co...
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.
Telleroo Webhooks
Outbound webhook events emitted by the Telleroo Business API (v1) and Partner API (v3). Each delivery is an HTTP POST to the subscriber URL configured in the Telleroo dashboard ...
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 Telleroo, 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.
