Tools (14)

As the server listed them on Oct 25, 2026. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • check_flowCheck a flowread-only

    Compile a flow document (flows-v1) with the same engine the API uses, and run its tests (flow-tests-v1) against in-memory data. Returns diagnostics (with JSON pointers into the document), what the flow reads and writes, and why each failing test failed. Costs nothing and sees no data.

  • check_write_rulesCheck write rulesread-only

    Compile a list's write rules with the same engine the API uses, and run their tests (a rules-tests-v1 document). Returns every diagnostic with its line and column, and for each failing test what it expected, what happened, and how each rule came out. Costs nothing and sees no data: lookups find the test document's items. Use it before saving rules.

  • eval_write_ruleTry a write against write rulesread-only

    Check one write against a rule set, as the API would, and say whether it would be allowed, denied (403) or failed (400), which statement decided it, and (with trace) what every expression evaluated to. The write is shaped like a rule test case: action, identity, token, old, new, patch, merge, now. Costs nothing and sees no data.

  • get_api_endpointGet a JSONPad API endpoint contractread-only

    The full contract of one REST API endpoint: parameters, headers, request body, responses and examples, and the JavaScript SDK method that calls it. Find it by id (the docs page slug, e.g. "item-restore"), by method and path (templates or concrete paths both work: "/lists/my-list/items/abc"), or by a description.

  • get_cli_commandGet a JSONPad CLI commandread-only

    The usage, arguments and options of a jsonpad command line tool (@basementuniverse/jsonpad-cli) command, and whether it works offline. Find it by name ("rules test", "jsonpad sync-schema --dry-run") or by what it does.

  • get_plan_limitsGet JSONPad plan limitsread-only

    The limits of each public plan (Free, Indie, Pro, Scale): requests per month and minute, the minimum gap between requests, storage, item size, versions kept, tokens, identities, realtime connections, webhooks and flows. null means unlimited. Sizes are in bytes, rateLimit in milliseconds, prices in GBP.

  • get_sdk_methodGet a JSONPad SDK methodread-only

    The signature, description and example of a method in the JavaScript SDK (@basementuniverse/jsonpad-sdk) or the realtime SDK, and the REST endpoint it calls. Find it by name ("restoreItem") or by what it does.

  • list_api_endpointsList the JSONPad API endpointsread-only

    List the REST API endpoints an API token can use, as method, path and title. Get one in full with get_api_endpoint.

  • list_docsList the JSONPad docs pagesread-only

    List the documentation pages by section, with a description of each: the table of contents.

  • lookup_errorLook up a JSONPad errorread-only

    What a JSONPad API error code means, its HTTP status, and the guides that explain it. Give the numeric code (10013) or the name (QUOTA_EXCEEDED), as found in an error response's "code" and "name".

  • read_docRead a JSONPad docs pageread-only

    Read a documentation page as markdown, or one section of it. Give a page slug ("indexing"), a /docs path, a jsonpad.io URL (with or without .md, and with an optional #anchor), "sdk/jsonpad-sdk", "sdk/jsonpad-realtime-sdk", "cli/reference" or "cli/readme". Long pages are cut at a section boundary; read on with the returned nextSection.

  • search_docsSearch the JSONPad docsread-only

    Search the JSONPad documentation, the JavaScript SDK references and the command line tool reference. Returns the best-matching sections with a snippet and their jsonpad.io URL; read one with read_doc. Exact identifiers work well: error codes and names, headers, SDK methods, CLI commands, $jsonpad-var variables, "POST /lists/{listId}/items".

  • validate_sync_documentValidate a schema sync documentread-only

    Check a schema sync document (sync-v1) as far as possible without an account: against the JSON schema the API uses, the API's rules for keys and indexes, and every rule set and flow in it with their tests. Documents that reference files (rulesFile, flowFile and their tests) are checked too if the files' contents are given in files. What a sync would change needs the account: the API server's plan_schema_sync, or jsonpad sync-schema --dry-run.

  • validate_token_permissionsValidate token permissionsread-only

    Check an API token's permission rules against the schema the API uses, say which rule shape a broken one was meant to be, and warn about valid rules that probably don't do what was meant (rule order, restore without view, sync-schema alone, allow "*").
