Run a public web search and return titles, URLs, and snippets as JSON.

Use when you need current public web results for a query. Do not use for private/intranet pages — call vc_page_markdown with a known URL instead. Sibling: vc_page_markdown (one URL), pay (generic slug caller).

Auth: free-trial or prepaid X-Vibes-Key preferred; else USDC via x402 (~$0.02). Side effects: outbound HTTP to a search provider; no local writes. Returns JSON results, or a payment_required challenge if unpaid.

Fetch a public webpage and return clean markdown plus extracted text.

Use when you already have a URL and need readable page content for an LLM. Do not use for search discovery — call vc_web_search first. Not for authenticated or paywalled pages.

Auth: free-trial or X-Vibes-Key preferred; else x402 (~$0.02). Side effects: outbound HTTP GET to the URL; no local writes. Returns JSON with markdown/text fields, or payment_required.

Repair malformed JSON from LLM output and return valid parsed JSON.

Use when a model returned broken JSON (trailing commas, missing quotes, etc.). Do not use for web fetching or search — use vc_web_search / vc_page_markdown.

Auth: free-trial or X-Vibes-Key preferred; else x402 (~$0.02). Side effects: none local; compute-only remote call. Idempotent for the same text. Returns repaired JSON, or payment_required.

Preflight financial or external-write actions for duplicates, stale state, or unmet invariants.

Use before spending money or writing outside the agent sandbox. Do not use for generic search — use vc_web_search. Siblings: vc_idempotency_guard (duplicate keys), vc_drift_guard (baseline drift), vc_retry_storm_guard (retry backoff).

Auth: X-Vibes-Key or x402 (~$0.02). Advisory only; no local writes. Returns GO/NO-GO style JSON with reasons, or payment_required.

Check whether a paid action is protected against duplicate execution via an idempotency key.

Use before retrying a payment or other side-effecting call. Do not use for content fetch — use vc_web_search / vc_page_markdown. Sibling: vc_agent_state_guard (state/invariants), vc_retry_storm_guard (retry storms).

Auth: X-Vibes-Key or x402 (~$0.02). Advisory only; no local writes. Returns JSON assessing key presence/durability, or payment_required.

Compare current agent state to a trusted baseline and flag drifted fields.

Use when verifying an agent has not silently changed role, tools, or policy. Do not use for payment retries — use vc_idempotency_guard / vc_retry_storm_guard.

Auth: X-Vibes-Key or x402 (~$0.02). Advisory only. Returns JSON listing drifted fields and severity, or payment_required.

Detect retry configs that amplify load instead of adding resilience.

Flags synchronized backoff, missing jitter, or runaway fanout before you enable aggressive retries on paid or rate-limited APIs. Sibling: vc_idempotency_guard for duplicate side effects.

Auth: X-Vibes-Key or x402 (~$0.02). Advisory only. Returns JSON risk assessment, or payment_required.

Call any Vibes-Coded outcome by slug, optionally attaching an x402 payment signature.

Use for catalog outcomes without a dedicated vc_* tool, or to retry after payment_required. Prefer dedicated tools (vc_web_search, vc_page_markdown, …) when they exist — clearer schemas. Do not use instead of health().

Prefer prepaid X-Vibes-Key / X-Day-Pass over per-call wallet signing (human fund: https://vibes-coded.com/start).

Args: slug: Outcome id, e.g. "web-search" or "agent-state-guard". payment_signature: Optional x402 PAYMENT-SIGNATURE header value. body: JSON object of endpoint fields (query, url, text, …).

Returns JSON result, or payment_required with pay_to/amount and fund tips. Side effects: may settle USDC via x402 when paying; otherwise HTTP only.

Return MCP server liveness: version, origin, tool count, and catalog size.

Use for hosted inspector probes (Glama / Smithery) or before diagnosing tool failures. Do not use for business outcomes — call vc_* tools or pay(slug=...) instead.

No auth required. No side effects. Returns JSON {ok, service, version, origin, tools, catalog_resources}.
