Every entry in the Catalog is an external AI service that prices each request on the wire, so your agent can pay per call — no signup, no API key at the provider, no subscription. This page covers what’s in the Catalog today and how to get your own service into it.

What’s available

Listings span a curated set of categories, each with granular sub-categories:

Data & Enrichment

Search & Research

Crypto & Blockchain

Finance & Markets

AI & Media

Web Scraping & Automation

Communication & Voice

…and more

The full set also includes Sales & Business Intelligence, Social & Creator, Identity & Compliance, Infrastructure & Compute, Weather, and Travel. Browse or query the live set — the current categories and their counts come from the read API, never a hard-coded list. See Discovering services. Each service settles on one of two payment rails the Router can pay:

What gets listed

The Catalog only lists services the Router can actually pay — those that price each request on the wire (x402 and MPP). Services that authenticate with a long-lived API key and bill you monthly aren’t listed: there’s no per-call price on the wire for the Router to settle. The Catalog surfaces only what an autonomous agent can buy, so it’s never handed a service it can’t pay for.

Add your AI Service

The Catalog is also where you list a service you own so other buyers’ agents discover and pay for it. From an organization in the Nevermined app, publish one of your registered agents into the Catalog with a category, its callable endpoint, and presentation details (title, description, logo, tags, features). You supply only presentation and the endpoint. Trust-sensitive facts are derived server-side rather than accepted from you — the payment protocol and price are detected from your endpoint, and ownership is taken from the agent — so a listing can’t misrepresent what it charges or who runs it.

Listed only once it’s validated healthy

Before your service goes live, a monitor probes the endpoint to confirm it actually responds — a listing is never published on your word alone. It also keeps checking after launch, so the Catalog stays a directory of services that currently work, not ones that used to. Each listing moves through a simple lifecycle:
Publishing requires an organization. See Agentic integration for the organization API context, and Register a plan and agent for creating the agent you’ll list.
