What Jina AI does that Spider does not
Jina AI passes clear product positioning, public docs discoverable, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, programmatic credential creation, machine-readable errors, rate-limit behavior predictable, and Spider 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
Spider fails clear product positioning, public docs discoverable, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, no mandatory sales call, programmatic credential creation, machine-readable errors, 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 Spider loses the points
| Pillar | Spider | What it measures |
|---|---|---|
| Discover | 73 | Can an agent find it at all: sitemap, robots, structured data. |
| Understand | 54 | Is there a spec, an llms.txt, a machine-readable description. |
| Adopt | 81 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 78 | Rate-limit headers, errors, status, and behaviour under load. |
Spider is weakest on understand at 54/100. 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, Spider may still be the right pick.

- 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.
