What Exa does that Patronus does not
Exa passes clear canonical domain, clear product positioning, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, programmatic credential creation, cli available, structured, predictable output, machine-readable errors, rate-limit behavior predictable, agent compatibility verified, and Patronus fails them. That is the whole of the gap between the two scores, so if none of those matter to your agent the ranking above overstates the difference.
Why people look for an alternative
Patronus fails clear canonical domain, clear product positioning, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, no mandatory sales call, programmatic credential creation, cli available, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
Where Patronus loses the points
| Pillar | Patronus | What it measures |
|---|---|---|
| Discover | 80 | Can an agent find it at all: sitemap, robots, structured data. |
| Understand | 46 | Is there a spec, an llms.txt, a machine-readable description. |
| Adopt | 75 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 35 | Rate-limit headers, errors, status, and behaviour under load. |
Patronus is weakest on operate at 35/100. Missing rate-limit headers mean an agent finds the limit by hitting it. If that is the part your agent depends on, take the ranking above seriously; if it is not, Patronus may still be the right pick.
What an agent runs into with Patronus
These are the findings from the last audit on 2026-09-01. Each one is a place unattended software stops, which is the practical reason to look at the list above.
- Flesh out the OpenAPI: paths, schemas, and descriptions.
- Document error responses as an enum in your OpenAPI.
- Let agents create API keys programmatically.
- Return X-RateLimit / Retry-After headers so agents pace themselves.
- Add request examples to your API reference.
- Add response examples to your API reference.
- Ship a CLI; it is an easy agent adoption path.
- Support an Idempotency-Key so retries are safe.
