## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-directory-rank-tracker-dc143918 -d '<json body>'
```

Example prompt: Track the directory ranking for my x402scan channel — it's currently ranked 11 and was ranked 18 last time, and its status is 'listed'. Tell me how many channels are listed and how many are approval-blocked.

## When to prefer this

Choose this endpoint when you need a deterministic, structured snapshot of directory rank positions and approval status for x402 seller channels, especially to detect rank movement (improvement or regression) between two time periods. Prefer it over manual tracking when comparing current vs previous rank across multiple channels programmatically.

## Known failure modes

- Missing required channel fields (name, rank, previousRank, status) causes validation error
- Empty channels array returns zero counts with no useful ranking delta
- Invalid rank integer types may cause schema rejection
- Service unavailable at the .xyz domain returns a non-200 error
- Payment failure (x402 protocol) blocks the request before processing

## How this service works

Operational x402 seller tools for market benchmark, buyer shortlist, seller action plan, directory rank tracker, quote inspector, competitor listing audit, directory submission kit, price band advice, and buyer intent scoring workflows.

## Output

Returns a JSON object with the list of tracked channels, a count of channels with 'listed' status, a count of channels blocked by approval, and the tool/route metadata. Results are deterministic given the same input.
