# Pricing

## The index is free.

The index is free for humans and for agents: the directory, the JSON API, the MCP server and the
natural-language endpoint, with no key, no account and no paid tiers. Listing a service is free;
submissions are reviewed before listing.

- Web directory: https://staging-next.superstables.com/discover - free, no account
- JSON API: https://staging-next.superstables.com/api/v1/services - free, no key, CORS open
- MCP server: https://staging-next.superstables.com/api/mcp - free, no auth
- Natural-language endpoint: https://staging-next.superstables.com/ask - free
- Listing a service: https://staging-next.superstables.com/submit - free; submissions are reviewed before listing

Services set their own prices, and network fees are separate. Payments through Superstables currently use test tokens only.

## Limits

Soft advisory limit of 300 requests per minute per client. Responses are CDN-cached
for 300 seconds. No paid tiers exist today; if that changes, this file changes first.
