Verisoul
Verisoul is a fake-account and fraud detection platform that helps businesses stop bots, fake signups, and multi-accounting. It combines device fingerprinting, network and location signals, bot detection, email intelligence (risk, deliverability, breach, and identity signals), phone validation, and account linking with an automated rules engine and ML models. Verisoul also offers hosted identity verification products — Face Match (liveness/selfie dedup) and ID Check (government-ID document verification) — and manages biometric capture, consent, and retention on the customer's behalf. It exposes a REST API (Account, Session, Lists, Phone, Email Intelligence, Face Match, ID Check) authenticated with an x-api-key header, plus web and mobile SDKs and signed webhooks. Verisoul is backed by 500 Global.
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 Verisoul the way a machine reads it — 23 machine-readable artifacts across 8 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 — Verisoul scores 49.5/100 (developing), with a separate agent-readiness read of 33/100 (agent ready). 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 Verisoul
Each block below is one kind of artifact we hold for Verisoul. 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 8
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.
Verisoul Account API
The Account API from Verisoul — 3 operation(s) for account.
Verisoul Email API
The Email API from Verisoul — 1 operation(s) for email.
Verisoul Enrollment API
The Enrollment API from Verisoul — 1 operation(s) for enrollment.
Verisoul List API
The List API from Verisoul — 3 operation(s) for list.
Verisoul Phone API
The Phone API from Verisoul — 1 operation(s) for phone.
Verisoul Public API

Verisoul Session API
The Session API from Verisoul — 4 operation(s) for session.
Verisoul Verification API
The Verification API from Verisoul — 3 operation(s) for verification.

Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.

RATE LIMITSEvent 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.

Verisoul Email Intelligence Webhooks
Asynchronous results for the Verisoul Email Intelligence API are delivered to your configured endpoint as signed webhooks. When an email submitted via POST /email (or the batch ...
ASYNCAPISecurity Posture 3
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.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.

This is an independent, third-party profile of Verisoul, 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.
