What Vellum does that Agno does not
Vellum passes structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, agent-compatible signup flow, programmatic credential creation, fast time to first request, copyable quickstart, cli available, machine-readable errors, retry behavior documented, and Agno 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
Agno fails structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, agent-compatible signup flow, programmatic credential creation, fast time to first request, copyable quickstart, 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 Agno loses the points
| Pillar | Agno | What it measures |
|---|---|---|
| Discover | 100 | Can an agent find it at all: sitemap, robots, structured data. |
| Understand | 31 | Is there a spec, an llms.txt, a machine-readable description. |
| Adopt | 65 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 65 | Rate-limit headers, errors, status, and behaviour under load. |
Agno is weakest on understand at 31/100. 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, Agno may still be the right pick.
What an agent runs into with Agno
These are the findings from the last audit on 2026-08-23. Each one is a place unattended software stops, which is the practical reason to look at the list above.
- Publish an OpenAPI spec so agents can generate a client.
- 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.
- Add a copyable quickstart so first success is fast.
