limit_count: 0
limit_count_note: >-
  The store states that a limit exists but publishes no number. There is no rate-limit reference
  page, no quantified limit, no window and no burst on any Agnikul host. An honest zero: a
  qualitative rate-limit statement is present, a quantified limit is not.

    result: >-
      No RateLimit-*, X-RateLimit-* or Retry-After header of any family was returned on a successful
      call. The agent has no remaining-budget signal and can only discover the ceiling by hitting it.

  non_standard_headers_observed:
  - name: shopify-complexity-score
    value_observed: '310'
    meaning: >-
      A per-request cost score, not a limit. It tells a client how expensive the call it just made
      was; no budget, window or remaining balance is returned alongside it.
  - name: shopify-complexity-score-v2
    value_observed: '31'
    meaning: A second-generation cost score on a different scale. Same limitation — cost without budget.
  - name: x-shopify-ucp-mcp-api-version
    value_observed: '2026-08-25'
    meaning: Echoes the UCP protocol version that served the request. Useful for pinning; unrelated to rate limiting.
  - name: x-request-id
    value_observed: '<uuid>-<epoch>'
    meaning: Per-request trace identifier.
  - name: server-timing
    meaning: 'processing/db durations plus edge, country, asn, servedBy and requestID descriptors. Diagnostic, not budget.'
  note: >-
    The substantive finding: this endpoint returns a COST signal and no BUDGET signal. An agent is
    told what it spent and never what it has left.

storefront_surface:
  scope: https://shop.agnikul.in read-only JSON routes (/products/*.json, /collections/*/products.json)
  documented: false
  note: >-
    The store documents these routes for agents in /agents.md but states no limit for them; the
    rate-limit sentence is scoped to the MCP endpoint only.

corporate_surface:
  scope: https://agnikul.in
  documented: false
  note: No API and therefore no limits. robots.txt carries no crawl-delay.

gaps:
- No numeric limit, window or burst published.
- No RateLimit-* or X-RateLimit-* response headers emitted on success.
- No Retry-After documented for the 429 the store tells agents to expect.
- A complexity/cost score is returned with no corresponding budget or remaining balance.
