Metadata

Metadata (metadata.io) is a B2B marketing automation and demand-generation platform that uses AI agents to plan, execute, and optimize paid advertising campaigns across LinkedIn, Meta (Facebook and Instagram), Google Search and Display, Reddit, and Bing. Its core products are Metadata Campaigns (automated full-funnel paid campaign execution), Metadata Audiences with the patented MetaMatch B2B audience engine for precision targeting, and Metadata Insights for real-time, revenue-focused performance analytics. The platform connects to ad channels, CRMs (Salesforce, HubSpot), and marketing automation platforms (Marketo, Pardot) to run multivariate campaign testing at scale and optimize for pipeline and revenue rather than lead volume. Backed by 500 Global and Partech. Metadata publishes no public REST API. Its developer surface is MCP-native: the MetadataONE MCP server at mcp-server.metadata.io/mcp exposes 141 documented tools across audiences, campaigns, creatives, offers, keywords, ad extensions, analytics and integrations, so an agent can build an audience, generate on-brand creative, assemble a campaign and launch real paid spend without a REST client or an SDK. Developer docs, a quickstart, an authentication and scopes reference and the full tool catalog are published at metadata.io/developers/.

Metadata publishes 2 API contracts indexed on the APIs.io network: Health API and MCP API. Tagged areas include Company, Marketing, Marketing Automation, Demand Generation, and Advertising.

The Metadata catalog on APIs.io includes 1 Spectral governance ruleset.

Metadata’s developer surface includes support, engineering blog, pricing, documentation, API reference, getting-started guide, and 17 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 does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

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/.
