Measured tools (17)

• get_service_info read-only

  Read Xcatcher's live capabilities, prices, limits, endpoints, and recommended agent workflow. Call this first when planning a crawl or when cached documentation may be stale. No points are consumed.

  Hints: read-only yes · destructive no · idempotent no · open-world no

• preflight_crawl read-only

  Normalize and deduplicate X handles, validate the mode, and preview the current modeled points/USDC cost. This free read-only check requires no account, creates no quote or task, and moves no funds. Use it before requesting a live x402 payment challenge.

  Parameters:

  • users (required) — array — X handles, @handles, or x.com/twitter.com profile URLs.
  • mode — string — API-key accounts use 1 point per normal handle and 10 per deep handle; direct x402 normal requests receive progressive batch pricing shown by preflight.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_sample_result read-only

  Return a stable synthetic example of Xcatcher's paginated result and coverage metadata. No live X data is fetched, no account is needed, no task or quote is created, and no funds move.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_account_balance read-only

  Return the account attached to the current Bearer API key and its points balance. Use before creating a task to estimate whether an x402 top-up will be needed. Read-only.

  Hints: read-only yes · destructive no · idempotent no · open-world no

• list_crawl_tasks read-only

  List recent tasks owned by the current Bearer API key, newest first. Use next_before_id for cursor pagination. Read-only and does not consume points.

  Parameters:

  • limit — integer — Tasks to return (1-100).
  • before_id — Cursor from next_before_id; omit for the newest tasks.

  Hints: read-only yes · destructive no · idempotent no · open-world no

• get_x402_quote

  Create a short-lived USDC quote for a requested number of Xcatcher points. Returns the exact live amount and supported Base/Solana payment requirements; it does not move funds. Ask the user before signing or sending any payment.

  Parameters:

  • points (required) — integer — Number of points to buy (1-200000). Live quote amount is authoritative.

  Hints: read-only no · destructive no · idempotent no · open-world yes

• get_direct_crawl_payment

  Create a request-bound x402 v2 payment requirement for an accountless crawl. Use this only for the accountless x402 path after preflight_crawl; API-key accounts use create_crawl_task instead. Normal requests use progressive batch pricing, so quote the complete deduplicated handle list together. This does not move funds. Return payment_required_b64 unchanged to an x402-compatible wallet/client; the live amount, asset, network, destination, and quoteId are authoritative.

  Parameters:

  • users (required) — array — X handles, @handles, or x.com/twitter.com profile URLs.
  • mode — string — Direct x402 normal requests use progressive batch pricing; deep is $0.10 per normalized requested handle. Always preflight the complete list.

  Hints: read-only no · destructive no · idempotent no · open-world yes

• submit_direct_crawl_payment destructive

  Submit an x402 v2 PAYMENT-SIGNATURE for the exact users/mode used by get_direct_crawl_payment. This may settle USDC and create a crawl task. Call only after explicit spending approval. On success, securely save task_token: it grants task-scoped result access for seven days.

  Parameters:

  • users (required) — array — The exact handles/profile URLs used for the payment requirement.
  • payment_signature_b64 (required) — string — The base64(JSON) PAYMENT-SIGNATURE produced for the accepted x402 v2 requirement.
  • mode — string — Must exactly match the quoted mode.

  Hints: read-only no · destructive yes · idempotent yes · open-world yes

• get_direct_task_status read-only

  Read an accountless paid crawl using its task_id and task-scoped token. Use this instead of get_task_status for an accountless x402 task. Poll every 5-10 seconds until task.has_result is true or it reaches failed/cancelled.

  Parameters:

  • task_id (required) — integer — Task ID returned after x402 settlement.
  • task_token (required) — string — Task-scoped xtask_ token returned after settlement or idempotent recovery.

  Hints: read-only yes · destructive no · idempotent no · open-world no

• get_direct_result_preview read-only

  Return structured JSON rows for a completed accountless paid crawl. Use this instead of get_result_preview for an accountless x402 task; API-key accounts use get_result_preview. Use offset for pagination; the task token is required and should be treated as a secret.

  Parameters:

  • task_id (required) — integer — Completed paid task ID.
  • task_token (required) — string — Task-scoped xtask_ token.
  • limit — integer — Rows to return (1-100).
  • offset — integer — Zero-based row offset.

  Hints: read-only yes · destructive no · idempotent no · open-world no

• create_crawl_task destructive

  Create a crawl task for one or more X (Twitter) usernames. Side effects: creates a new task AND consumes points. If points are insufficient, upstream returns HTTP 402 with PAYMENT-REQUIRED (quote). This tool surfaces it as error.code=PAYMENT_REQUIRED with payment_required payload so agents can request spending approval, top up, then retry safely. Modes: - normal: Fast latest-post snapshot at scale (fresh-feed monitoring). Optimized for high-throughput batch retrieval. - deep: Deeper per-user collection/enrichment (typically slower; higher resource usage). Use when you need more than a quick latest-post snapshot. Performance note: Normal mode is optimized for a small latest-post snapshot per handle. Actual completeness and latency depend on X availability, upstream limits, and network conditions. Batching: For very large sets, split users into batches. Suggested upper bound per task: 500 users (configurable via MAX_USERS_PER_TASK). Reliability: - Use idempotency_key to make retries safe (avoid duplicate charges). - After creation, poll get_task_status every 5–10s until has_result=true. - Then call get_result_download_url (download still requires the same Bearer token).

  Parameters:

  • users (required) — array — Array of X usernames (handles). You may include a leading '@'.
  • mode — string — normal = fast latest-post snapshot at scale; deep = deeper per-user collection (slower).
  • idempotency_key — Optional idempotency key for safe retries (recommended for agents).

• x402_topup destructive

  Top up points for the CURRENT Bearer key using x402 proof. Inputs: - quote_id: returned by PAYMENT-REQUIRED (or /api/v1/x402/quote) - payment_signature_b64: base64(JSON) that will be passed as HTTP header PAYMENT-SIGNATURE Side effects: credits points to the same Bearer key (no key rotation). On success returns credited_points and balance_after (shape depends on upstream).

  Parameters:

  • quote_id (required) — string — Quote ID returned by PAYMENT-REQUIRED (or /x402/quote).
  • payment_signature_b64 (required) — string — Base64(JSON) for header PAYMENT-SIGNATURE.

  Hints: read-only no · destructive yes · idempotent yes · open-world yes

• get_task_status read-only

  Get API-key account task status by task_id (read-only); accountless x402 tasks use get_direct_task_status instead. Recommended polling interval: every 5–10 seconds until has_result=true. Returns safe structured state, result metadata, and authenticated result URLs; server filesystem paths are never exposed.

  Parameters:

  • task_id (required) — integer — Task ID returned by create_crawl_task.

  Hints: read-only yes · destructive no · idempotent no · open-world no

• wait_for_task read-only

  Poll a crawl task server-side until it has a result, reaches a terminal failure/cancelled state, or the bounded timeout expires. Read-only and cheaper for agent context than repeated manual polling.

  Parameters:

  • task_id (required) — integer — Task ID returned by create_crawl_task.
  • timeout_seconds — integer — Maximum wait in seconds (5-120).
  • poll_interval_seconds — integer — Seconds between status checks (2-15).

  Hints: read-only yes · destructive no · idempotent no · open-world no

• get_result_preview read-only

  Return up to 100 result rows from an API-key account task as native structured JSON for direct agent analysis; accountless x402 tasks use get_direct_result_preview instead. Use offset/next_offset for pagination; this does not download or parse XLSX. Use after has_result=true; use get_result_download_url when the complete XLSX is required. Read-only.

  Parameters:

  • task_id (required) — integer — Completed task ID owned by the current API key.
  • limit — integer — Maximum result rows to return (1-100).
  • offset — integer — Zero-based row offset for pagination.

  Hints: read-only yes · destructive no · idempotent no · open-world no

• get_result_download_url read-only

  Get an absolute download URL for a task result (read-only). If the task is not finished, returns ok=false with code=RESULT_NOT_READY (HTTP 409). Downloading the URL requires the same Authorization: Bearer token.

  Parameters:

  • task_id (required) — integer — Task ID. Must be completed (has_result=true).

  Hints: read-only yes · destructive no · idempotent no · open-world no

• cancel_task destructive

  Cancel a queued task by task_id. Side effects: changes task state. Xcatcher refunds cost_points when a queued task is successfully cancelled.

  Parameters:

  • task_id (required) — integer — Task ID to cancel.
