What Zuplo does that Unkey does not
Zuplo passes llms-full.txt / full agent docs, mcp discoverable, agent-compatible signup flow, mcp integration available, structured, predictable output, agent compatibility verified, and Unkey 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
Unkey fails llms-full.txt / full agent docs, mcp discoverable, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, mcp integration 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 Unkey loses the points
| Pillar | Unkey | What it measures |
|---|---|---|
| Discover | 80 | 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 | 55 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 35 | Rate-limit headers, errors, status, and behaviour under load. |
Unkey 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, Unkey may still be the right pick.
