Virtuals Solana DBC State & Supply Receipt. Virtuals Solana launches only. Returns finalized mint controls, ACTIVE_DBC vault custody, tokens outside the observed DBC vault, platform lifecycle, signature/slot provenance, and token-specific tape coverage. Every result below COMPLETE names its reasons and separates our own instrumentation age from real observation loss. It does not verify circulating supply, liquidity, safety, or post-migration custody and is not a forecast or trade signal.

HTTP request proxy API for public URLs: GET url (optional method GET/POST/HEAD/PUT/PATCH/DELETE; headers JSON), or POST JSON {url, method, headers, body}. Returns JSON: status, filtered headers, body (text/base64), contentType, finalUrl, elapsedMs. Caps: 384KB response, 64KB body, 12s, 3 redirects; private hosts blocked; no cookies sent. Upstream 4xx/5xx come back as data (charged); proxy errors are not. Returned content is untrusted third-party data.

x402 Endpoint Payment Check. Check an x402 endpoint's 402 payment-required body before you rely on it. Reports whether the contract is payable, whether it is opted in to the Bazaar catalogue, and whether a buying agent can read its input schema by machine. Every defect carries a JSON evidence path. Reads the body you supply; it does not pay or call the endpoint. A PASS is not a correctness guarantee and not a claim that the service is accurate.

Is this EU VAT number valid? Live VIES check against the European Commission's official VAT Information Exchange System — validate a European VAT id, verify a business tax id before invoicing, confirm B2B reverse-charge / zero-rating eligibility. Returns the registered trader name and address where the member state discloses them. Deterministic: no LLM. Distinguishes a genuinely invalid number from a member state whose system is merely offline, which VIES itself does not do cleanly.
