What Permit.io does that Speakeasy does not
Permit.io passes search discoverable, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, programmatic credential creation, cli available, machine-readable errors, and Speakeasy 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
Speakeasy fails search discoverable, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, self-service signup, no mandatory sales call, programmatic credential creation, fast time to first request, cli available, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
Where Speakeasy loses the points
| Pillar | Speakeasy | What it measures |
|---|---|---|
| Discover | 87 | 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 | 55 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 67 | Rate-limit headers, errors, status, and behaviour under load. |
Speakeasy is weakest on understand at 46/100. Without a spec an agent has to guess at endpoints, and it guesses wrong. If that is the part your agent depends on, take the ranking above seriously; if it is not, Speakeasy may still be the right pick.
What an agent runs into with Speakeasy
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.
- Make signup self-serve; an agent cannot sit through a sales call.
- 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.
