Browse payment-enabled services in [the services llms.txt catalog](/services/llms.txt).

## Agent discovery

Agents can use the MPP services catalog before choosing which paid API to call:

| Surface | URL | Use it for |
| --- | --- | --- |
| Web directory | [`https://mpp.dev/services`](https://mpp.dev/services) | Browse services, categories, providers, endpoints, and examples. |
| Public catalog API | [`https://mpp.dev/api/services`](https://mpp.dev/api/services) | Fetch the JSON catalog directly from scripts, CLIs, or custom agents. |
| Services MCP | [`https://mpp.dev/mcp/services`](https://mpp.dev/mcp/services) | Let an MCP-capable agent rank services, inspect payment offers, get usage recipes, and fetch advisory OpenAPI summaries. |

The services MCP server is read-only. It does not register services, execute
payments, sign transactions, or proxy paid API calls. Runtime `402` Challenges
from the target service remain the authoritative source of current payment
terms.

For MCP client setup, Inspector smoke tests, agent prompts, and recommended
tool-call recipes, see

## List your service

The curated directory accepts live, production-ready MPP services. To submit yours:

1. Make sure your service is live and accepts MPP payments.
2. Gather its public URL, documentation, endpoints, payment methods, and pricing.
3. Open a pull request using the [service pull request template](https://github.com/tempoxyz/mpp/blob/main/.github/PULL_REQUEST_TEMPLATE/service.md).

We prioritize high-quality, novel services and may decline duplicate or incomplete listings. For immediate discovery outside the curated directory, you can also [register on MPPScan](https://www.mppscan.com/register).
