description: >-
  Explorium ships no test mode. There is no test-vs-live key separation, no
  sandbox host, no magic test identifiers and no fixture data - every call goes
  against live data and spends real credits from the one shared pool. What it
  offers instead is a browser playground for the MCP tools, a 100-credit free
  trial that behaves exactly like production, and three genuinely useful
  pre-flight affordances: a webhook connectivity check, an MCP cost estimator,
  and an MCP result sampler.
test_mode:
  separate_keys: false
  key_prefixes: none
  sandbox_host: none
  magic_test_values: none
  fixture_data: none
  time_simulation: none
  note: >-
    A single api_key authorizes production against real data. There is no way to
    exercise the API without consuming credits, which makes CI and integration
    testing a paid activity.
surfaces:
- name: MCP Playground
  url: https://www.explorium.ai/mcp-playground/
  type: hosted-console
  auth: browser session
  note: >-
    Try the MCP tools in a browser without wiring an MCP client. The closest
    thing Explorium has to a console.
- name: Free trial
  url: https://www.explorium.ai/sign-up/
  type: production-with-quota
  credits: 100
  validity_days: 90
  note: >-
    Not a sandbox - production access with a small budget. Once the 100 credits
    are spent or 90 days pass, calls fail with 403 insufficient credits.
- name: Interactive API reference
  url: https://developers.explorium.ai/reference/quick-starts/quick-starts
  type: docs-try-it
  note: Mintlify "try it" panels execute against production with the caller's own key.
pre_flight_tools:
- name: check_webhook_connectivity
  surface: rest
  endpoint: POST https://api.explorium.ai/v1/webhooks/check_connectivity
  purpose: Verify a registered webhook endpoint responds correctly before enrolling entities.
- name: estimate-cost
  surface: mcp
  purpose: Estimate the credit cost of an operation before running it.
  note: >-
    The single most useful safety feature for an autonomous agent on this API,
    and it exists only on MCP - a REST integrator has no equivalent.
- name: show-sample
  surface: mcp
  purpose: Preview sample rows from a result table before paying for a full export.
- name: WebhookSimulation
  surface: rest
  schema: WebhookSimulation / WebhookSimulationEventType
  note: >-
    Simulation schemas exist in the OpenAPI components, indicating some
    event-simulation capability, but no operation in the harvested spec exposes
    them and the docs do not describe how to trigger one.
cost_control:
  per_call_reporting: https://developers.explorium.ai/reference/credits/per-call-credit-usage
  balance: GET https://api.explorium.ai/v1/credits (get_active_credits_summary)
  consumption: POST https://api.explorium.ai/v1/credits/aggregation (get_credit_aggregation)
  note: >-
    Per-call credit reporting is opt-in and returns the exact credits deducted
    inside the response - the substitute for a test mode is careful accounting
    after the fact.
