Clay

Clay is an AI-native sales prospecting and GTM data orchestration platform built around Clay Tables — spreadsheet-like workspaces that combine 150+ data providers, AI research agents, and outbound automations. Clay's developer surface is integration-oriented rather than a traditional public REST API: HTTP API enrichment columns, incoming and outgoing webhooks, a Chrome extension, and native connectors to CRMs, sequencers, and data providers. External systems push data into Clay Tables and consume enriched rows via webhooks or exports back to systems of record.

Clay publishes 4 APIs on the APIs.io network, including Me API, Routines API, Search API, and 1 more. Tagged areas include Prospecting, Go-To-Market, Sales, Enrichment, and Automation.

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

Clay’s developer surface includes changelog, CLI, API reference, getting-started guide, support, authentication, documentation, and 39 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

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/clay-com: open an issue to ask a question, or submit a pull request to add artifacts.
