GoNitro
Nitro Software (GoNitro) is a document productivity company providing PDF editing, electronic signatures, redaction, and intelligent document automation for enterprises, small businesses, and professionals. Nitro exposes two public REST APIs on api.gonitro.dev: the Nitro PDF Services API (convert, transform, extract, and generate PDFs — conversions, compression, merge/split, OCR, redaction, PII detection, table and form extraction, and archival PDF/A) and the Nitro Sign API (enterprise eSignature envelope, document, participant, and field workflows with sealed documents and audit trails). Both use machine-to-machine OAuth 2.0 client-credentials, short-lived JWT bearer tokens, RFC 9457 problem+json errors, and asynchronous job processing. Nitro is ISO 27001, SOC 2, and HIPAA compliant and an accredited eIDAS Qualified Trust Service Provider.
Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.
API Evangelist profiles GoNitro the way a machine reads it — 32 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 — GoNitro scores 56.9/100 (strong), with a separate agent-readiness read of 29/100 (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 GoNitro
Each block below is one kind of artifact we hold for GoNitro. 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.
GoNitro Authentication API
The Authentication API from GoNitro — 1 operation(s) for authentication.
GoNitro Conversions API
The Conversions API from GoNitro — 1 operation(s) for conversions.
GoNitro Extractions API
The Extractions API from GoNitro — 1 operation(s) for extractions.
GoNitro Generations API
The Generations API from GoNitro — 1 operation(s) for generations.
GoNitro Jobs API
The Jobs API from GoNitro — 2 operation(s) for jobs.
GoNitro Platform API
The Platform API from GoNitro — 6 operation(s) for platform.
GoNitro Sign API
The Sign API from GoNitro — 22 operation(s) for sign.
GoNitro Transformations API
The Transformations API from GoNitro — 1 operation(s) for transformations.

Postman Collections 8
A runnable collection turns the contract into something a developer can execute in seconds. We profile them because the fastest way to trust an API is to make a real call against it.
Ready-to-run Postman collections for exercising this provider's APIs.

Open Collections 9
Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

Arazzo Workflows 1
Real integrations are rarely a single call. Arazzo describes the multi-step sequences — auth, then create, then confirm — so both a human and an agent can follow the choreography, not just the endpoints.
Multi-step API workflows described with the Arazzo specification.
Create and send a Nitro Sign envelope
Authenticate, create an envelope, add a document, participant, and signature field, then send it for signing.
ARAZZOMCP Servers 1
Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Nitro PDF Services MCP
MCP SERVEREvent 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.
Nitro Sign & PDF Services Webhooks
Event surface for Nitro. Sign delivers envelope lifecycle webhooks (HTTP POST) signed with RFC 9421 HTTP Message Signatures (HMAC-SHA256; headers Content-Digest, Signature-Input...
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.

Gonitro Trust Center
ISO 27001, SOC 2, HIPAA, QTSP (Qualified Trust Service Provider, accredited by LSTI under eIDAS), EU-U.S. Data Privacy Framework (with UK and Swiss extensions)
SECURITYAgentic 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 GoNitro, 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.
