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.

human only

More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.

Kin Score

API Evangelist profiles Clay the way a machine reads it — 11 machine-readable artifacts across 6 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 — Clay scores 29.7/100 (emerging), with a separate agent-readiness read of 7/100 (human only). 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 Clay

Each block below is one kind of artifact we hold for Clay. 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 6

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.

Clay HTTP API Enrichment

Generic HTTP request column inside Clay Tables that lets users call any external REST or GraphQL endpoint with row-level variables and write the response back into Clay. Acts as...

Clay Incoming Webhooks

Webhook source that pushes data from any external system into a Clay Table as new rows. Used to trigger Clay workflows from CRMs, signal providers, and product events.

Clay Outgoing Webhooks

Action column that POSTs enriched row data to an external webhook URL, used to deliver Clay-produced data to CRMs, sequencers, Slack, and custom backends.

Clay Tables

The core spreadsheet-style workspace that combines source rows, enrichment columns, conditional logic, AI agents, and write-back destinations. Tables are the unit of automation ...

Clay Integrations

Catalog of native connectors and 150+ data providers — Salesforce, HubSpot, Pipedrive, Apollo, Clearbit, ZoomInfo, LinkedIn Sales Navigator, Smartlead, Instantly, Apollo, OpenAI...

Clay Chrome Extension

Browser extension for scraping LinkedIn profiles and other web pages directly into Clay Tables, used to bootstrap prospect lists from manual research.

GraphQL 1

Where a provider ships GraphQL, the schema is the contract. We profile it alongside the REST surface so the whole interface is legible in one place.

GraphQL schemas published by this provider.

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.

Rate 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.

FinOps 1

Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Cost, billing, and metering signals for API financial operations.

Security Posture 1

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.
