## 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 friction-logs-api-fetch-log-by-slug-9793b650
```

Example prompt: Can you pull up the complete friction log for the slug 'agentcard' — I want to see the full record of provider attempts, blockers, workarounds, and outcomes?

## When to prefer this

Use this endpoint when you have a specific friction log slug (obtained from GET /v1/logs) and need the complete Markdown record for that log entry. It is the right choice when you need full detail — blockers, workarounds, outcomes, timestamps — for a single known log rather than browsing a list.

## Known failure modes

- Slug not found (404): the provided slug does not match any published log
- Invalid or missing slug query parameter returns a validation error
- Unpublished or draft slugs may not be accessible
- Payment failure (402): x402 payment of 1 USDC not completed or invalid
- Rate limiting or network errors from the upstream host

## How this service works

Provide a published slug from GET /v1/logs. Receive JSON with the complete Markdown record of our direct provider attempts, chronological blockers, impact, workarounds, outcomes, and the last-update time.

## Output

A JSON object containing the slug identifier, a human-readable title, the full Markdown text of the friction log (covering chronological provider attempts, blockers, impact, workarounds, and outcomes), and an ISO 8601 updated_at timestamp indicating when the log was last modified.
