Do AI agents pick your API?
Agents don't read your landing page. They query a directory, compare a few candidates and call one. Prowl is that directory: we count how often agents are shown your service, where you rank in your category, and who gets picked instead.

What's in the report
| Signal | Why it matters to an agent |
|---|---|
| Agent impressions (30 days) | How often your service was returned by /discover, semantic search, compare and the MCP gateway. |
| Category rank | Agents take the top few results. Rank 7 is close to invisible. |
| Competitors picked instead | The services agents chose when they had you as an option. |
| Missing signals | OpenAPI spec, llms.txt, MCP manifest, auth an agent can complete without a human. |
| Score | Measured by real benchmark calls, capped until you prove you own the domain. |
How to raise it
Claim your listing (free, DNS or file proof), publish a machine-readable spec, and make sure an agent can get a key without a CAPTCHA. The ASO guide covers the eight dimensions in detail.
