MNTN
MNTN (mountain.com) is a Connected TV performance marketing platform that lets brands plan, launch, target, measure, and optimize outcome-based TV advertising across streaming inventory. Its programmable surface is two distinct HTTP APIs: the Performance TV (PTV) platform API at api.mountain.com, an OpenAPI 3.1 contract covering advertisers, organizations, campaigns, flights, creatives, audiences and geo-lists, conversion pixel setup and verification, attribution windows and estimates, private marketplace (PMP) partners/deals/deal-groups/channels, reference vocabularies, and reporting; and the Reporting API 3.0 at api3.mountain.com, a partner reporting surface (/apilist metadata, /apidata query execution) plus an asynchronous /batch CSV export API that returns time-limited signed download URLs. Both are documented with published OpenAPI definitions rendered through Scalar. Authentication is an MNTN-issued advertiser API key (X-API-Key header on the platform API, key query parameter on the reporting API) or a bearer JWT. Errors are RFC 9457 problem+json with traceId and errorCode.
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 MNTN the way a machine reads it — 26 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 — MNTN scores 50.7/100 (developing), with a separate agent-readiness read of 47/100 (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.

How we profile MNTN
Each block below is one kind of artifact we hold for MNTN. 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 3
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.
MNTN Performance TV (PTV) API
OpenAPI 3.1 platform API for MNTN Performance TV. Covers advertisers and organizations, campaign and flight lifecycle (create, update, launch, pause, archive), creatives, audien...
MNTN Reporting API 3.0
Public partner reporting surface at api3.mountain.com. GET /apilist returns the tables and columns available to the authenticated advertiser; GET and POST /apidata execute multi...
MNTN Async Batch Export API
Asynchronous CSV export API under /batch on api3.mountain.com, for reporting queries too large or slow to run synchronously (a 413 on /apidata is the documented trigger). POST /...
Open Collections 17
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.
Open, tool-agnostic API collections (OpenAPI-derived and Bruno).

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 six things the Kin Score reads for commercial clarity.
Published pricing tiers and plan structures.

PLANSRate 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 LIMITSSecurity Posture 4
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.

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