For Agents

Score, scan, and enrich any domain for AI citation readiness, llms.txt compliance, MCP endpoint detection, and agentic commerce signals across roughly 200 endpoints.

Quickstart

Get started with Citability API in minutes using your preferred integration method.

# Add to your MCP client config (Claude Desktop, Cursor, Windsurf)
{
  "jentic": {
    "url": "https://api.jentic.com/mcp",
    "auth": "oauth"
  }
}

# Then ask your agent:
"score a domain for AI citation readiness"

# → Jentic returns the GET /events tool with parameter schema, agent executes.

Capabilities

Jentic publishes the only available OpenAPI document for Citability API, keeping it validated and agent-ready.

Jentic publishes the only available OpenAPI specification for Citability API, keeping it validated and agent-ready. Citability is a domain intelligence platform that scores AI visibility, citation readiness, and agentic commerce readiness across more than 600 million domains. The API exposes around 200 endpoints for scanning a domain, scoring it against the AI Discovery Protocol (ADP), validating llms.txt and Schema.org markup, detecting MCP endpoints, and pulling enrichment data such as verticals, leads, and directory entries. It is designed for SEO and AI-readiness teams that need programmatic access to citation and discoverability signals.

Use Cases

Patterns agents use Citability API API for, with concrete tasks.

★ Bulk AI-readiness audit for a website portfolio

An SEO or AI-readiness team submits up to thousands of portfolio domains via POST /api/v1/scan/batch, gets back ADP scores covering llms.txt, Schema.org, and content extractability, and rolls the results into a quarterly readiness report. The unified scan endpoint adds a 3-pillar score combining visibility, citation, and agentic commerce.

Call POST /api/v1/scan/batch with an array of 50 domains, then aggregate the ADP scores by category and identify the bottom-quartile domains.

Sales intelligence for AI-native tooling

A vendor selling AI-readiness products pulls filtered leads from /api/v1/leads, segments them by vertical via /api/v1/leads/verticals, and exports a target list as CSV. Each lead includes Citability's priority and ADP scores so the sales team can lead with a specific gap (no llms.txt, missing Schema.org, no MCP endpoint).

Call GET /api/v1/leads with a vertical filter for 'e-commerce' and a max ADP score of 40, then export the result via GET /api/v1/leads/export.

MCP endpoint discovery across a directory

An agent platform team uses Citability's directory and scan endpoints to discover which domains expose MCP endpoints. Domains in the directory are scored for agentic commerce readiness, so the team can prioritise integration partners that already speak MCP rather than cold-emailing every vendor.

Call GET /api/v1/directory/search with a query for 'mcp' and filter the result to entries where the agentic commerce score is above 70.

AI agent-driven domain enrichment via Jentic

An agent loaded with the Citability tool through Jentic searches by intent ('score a domain for AI readiness'), receives the schema for /api/v1/domain/{domain}, and enriches a CRM record with the citation score, ADP gaps, and recommended fixes. This turns Citability into a callable tool inside any agent workflow.

Through Jentic, search 'score a domain for AI readiness', load the schema for /api/v1/domain/{domain}, and call it for the prospect's domain.

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Any Citability account token is stored encrypted in the Jentic vault (MAXsystem). Agents receive scoped execution access — the raw token never enters the model context.

Intent-based discovery

Agents search by intent (e.g. 'score a domain for AI readiness') and Jentic returns the matching Citability operation with its input schema, so the agent calls the right endpoint across the 200-endpoint surface without browsing docs.

Time to first call

Direct Citability integration: 1-2 days to map the 200-endpoint surface and decide which scan and lead endpoints to call. Through Jentic: under an hour — search, load schema, execute.

FAQs

Specific to using Citability API API through Jentic.

Why is there no official OpenAPI spec for Citability API?

Citability does not publish an OpenAPI specification on its public site. Jentic generates and maintains this spec so that AI agents and developers can call Citability API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the Citability API use?

The OpenAPI spec does not declare a security scheme on the public endpoints; Citability typically gates production usage behind an account-level token issued from the dashboard at citability.ai. Through Jentic, any required token is held in the encrypted MAXsystem vault and injected at execution time.

Can I score a single domain for AI readiness?

Yes. GET /api/v1/domain/{domain} returns the AI opportunity score for one domain, and GET /api/v1/scan/{domain} returns the ADP compliance breakdown (llms.txt, Schema.org, MCP detection, content extractability) for the same domain.

Can I score many domains in a single call?

Yes. POST /api/v1/domain/batch accepts an array of domains and returns scores for each, and POST /api/v1/scan/batch does the same for full ADP scans. This is the recommended way to audit a portfolio of websites.

What are the rate limits for the Citability API?

The OpenAPI spec does not declare rate limits. Citability enforces them at the account level, so production integrations should add retry-with-backoff on 429 responses and prefer the batch endpoints over single-domain loops.

How do I score a domain from an AI agent through Jentic?

Run pip install jentic, then have the agent search 'score a domain for AI readiness', load the schema for GET /api/v1/domain/{domain}, and execute the call. Jentic resolves any required credential and returns the JSON score directly to the agent.
