## TL;DR
"No value found" means the path is wrong, the mount is wrong, or you asked KV v2 for a path that needs the `/data/` segment (API only; the CLI handles it). List the mount, list the path, and read the exact key. The value appears once the path is right.

## Error
```text
vault kv get: no value found at path
```

## Steps
1. List the mounts: run `vault secrets list` and confirm the KV engine is mounted where you think it is. Expected: you see the mount path and whether it is KV v1 or v2.
2. List the path: run `vault kv list` on the parent path to see what actually exists. Expected: the real key names, which often differ by a prefix or pluralization from what you guessed.
3. For API users on KV v2: insert `/data/` after the mount in the API path (for example `secret/data/myapp` instead of `secret/myapp`). The CLI does this for you; raw API calls do not. Expected: the API returns the secret.
4. Check for a typo in the final key segment: paths are case-sensitive and trailing slashes matter. Expected: the exact stored key name.
5. Retry `vault kv get` with the corrected path. Expected: the secret data returns.

## When to use
- `vault kv get` reports no value at a path you believe exists
- API reads fail while CLI reads work (the `/data/` segment issue)
- After migrating between KV v1 and v2

## When not to use
- Permission denied errors (policy problem, not path)
- The engine is not mounted at all (mount it first)

## Tool compatibility
- HashiCorp Vault KV v1/v2 (`vault kv get`, `vault kv list`, HTTP API)

## Variant phrasings
### vault api returns 404 on kv v2 path
Add the `/data/` segment to the API path; the CLI adds it silently, the API does not.

### kv get empty after engine upgrade
A v1 to v2 migration changes read semantics; verify the mount version with `vault secrets list -detailed`.

## Why it happens
KV v2 stores versions under a `/data/` subpath and metadata under `/metadata/`, while the CLI abstracts this away. Anyone calling the HTTP API directly, or guessing a path from memory, hits the wrong location and gets a clean "no value found" instead of a helpful redirect.
