Skribble
Skribble (Skribble AG) is a Swiss electronic signature provider offering simple (SES/EES), advanced (AES/FES) and qualified (QES) electronic signatures that are legally valid under Swiss ZertES and EU eIDAS law, hosted in Switzerland and GDPR-compliant. Beyond its web app, Skribble publishes a developer portal at api.docs.skribble.com documenting the Sign API v2 (stable), Sign API v3 (preview, with draft workflows and multi-document requests) and the Validation API v1 for verifying signed PDFs and certificates.
Reference-quality API operations across every facet — a rich contract, published governance, transparent operations, and machine-readable commercial terms.
API Evangelist profiles Skribble the way a machine reads it — 49 machine-readable artifacts across 3 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 — Skribble scores 70.7/100 (exemplar), with a separate agent-readiness read of 32/100 (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 Skribble
Each block below is one kind of artifact we hold for Skribble. 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 17
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.
Skribble Access API
Endpoints for authentication, authorization, and user access management.
Skribble Additional Information API
Endpoints providing extra metadata or supplementary details for documents.
Skribble Billing and Credits API
Endpoints for managing account credits, billing information, and payment operations.
Skribble Document API
Endpoints for uploading and managing documents.
Skribble Identification API
Endpoints for retrieving, checking status, and downloading identification evidence collected during identification.
Skribble Monitoring API
Endpoints for monitoring system health.
Skribble Report API
Endpoints for signature activity reporting.
Skribble Reports API
Endpoints for generating, retrieving, and managing reports related to document processing.
Skribble Seal API
Endpoints for applying electronic seals to documents.
Skribble Send To API
Endpoints for the Send-To signing flow.
Skribble Signature API
Endpoints for creating and managing signature requests.
Skribble Signature Attachment API
Endpoints for managing attachments on a signature request.
Skribble Signature Handling API
Endpoints for handling signature requests and callbacks.
Skribble Signature Observer API
Endpoints for managing observers on a signature request.
Skribble Signature Signer API
Endpoints for managing signers on a signature request.
Skribble User API
Endpoints for user information and signature quality queries.
Skribble Validation API
Endpoints to validate documents, data formats, and signatures.

Agent Skills 9
An agent skill packages the how-to for driving these APIs from an assistant — the prompts, the sequence, the guardrails — so the knowledge to use the API travels with it.

Pricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
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.
Skribble Rate Limits
RATE LIMITSSemantic Vocabularies 1
JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.
JSON-LD contexts and semantic vocabularies used across these APIs.

JSON-LDSpectral Rules 1
Governance rulesets we run against this provider's specs — the automated checks behind parts of the score. Profiling them makes the quality bar explicit and re-runnable, not a matter of opinion.

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

Security 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.
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.
OAuth scopes governing access to this provider's APIs.
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 Skribble, 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.
