Ploy

Ploy is an AI-powered web marketing automation platform that turns a company's marketing website into a growth channel. Founded in 2025 by former Webflow CTO Bryant Chou, backed by Y Combinator and First Round Capital ($27M), Ploy runs AI agents that build and optimize Astro/Tailwind marketing sites, write copy, run technical SEO and answer-engine optimization, identify visiting companies without cookies, launch ad campaigns, and execute reusable multi-step workflows called Ploybooks. Its programmable surface is deliberately CLI-first rather than REST-first: Ploy publishes no OpenAPI and no public API reference, but it does ship a standalone `ploy` CLI binary (workspaces, sites, publishing, variables and secrets, documents, Ploybooks, databases, Code Sync, and design-system inspection) authenticated by workspace-scoped API tokens for headless CI and remote coding agents, an installable Agent Skills catalog (`ploy skills init`), and one public HTTP endpoint — an authenticated inbound webhook ingest at /api/v1/webhook/{endpointSlug} that stores arbitrary JSON and triggers a Ploybook.

Ploy publishes 1 API on the APIs.io network. Tagged areas include Company, Marketing, Marketing Automation, Artificial Intelligence, and AI Agents.

The Ploy catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Ploy’s developer surface includes authentication, changelog, CLI, engineering blog, pricing, signup flow, documentation, and 29 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/ploy: open an issue to ask a question, or submit a pull request to add artifacts.

  name: Ploy Webhook Ingest API
  description: The only public HTTP endpoint Ploy documents. An authenticated inbound ingest endpoint that accepts any well-formed
    JSON object (up to 1 MB) from an external system — Clay, Stripe, Zapier, or a custom backend — stores it verbatim with
    its timestamp and source endpoint, and optionally runs a Ploybook with the payload injected as prompt context. Each endpoint
    has its own bearer key, shown once at creation. POST only; 202 on acceptance; documented 400/401/403/404/413/415/429 failures.
    Ploy does not retry inbound events and publishes no idempotency key, so senders must retry on 5xx and 429 with backoff
    and dedupe on their own side.
