Live Gnosis Chain on-chain data as an API, built on the open Blockscout explorer. Gnosis Chain (chain id 100, formerly xDAI) is a long-running Ethereum-compatible network whose native currency is the xDAI stable token, so gas and balances are denominated in a dollar-pegged coin. Pull network stats (total blocks and transactions, native price, live gas), a gas oracle with slow, average and fast prices in gwei, the most recent blocks and full block detail by height or hash. Look up any address for its balance and contract status, any transaction by hash for its value, fee, status, sender and receiver, and any ERC-20 token by contract for its name, symbol, decimals, holders and USD rate. A universal search resolves addresses, tokens, blocks and transactions in one call. Real on-chain data, no key needed upstream. Ideal for Gnosis wallets, block explorers, gas trackers, DeFi dashboards and on-chain analytics.

Validate and decode Indian GSTINs (the 15-character Goods & Services Tax Identification Number) instantly and entirely offline. The validate endpoint checks the structure and recomputes the official GSTIN check digit — the base-36 weighted algorithm the GSTN itself uses — and confirms the embedded state code is real, returning a clear valid/invalid verdict with the specific reasons a number fails. The decode endpoint breaks a GSTIN into its parts: the GST state/UT code and its name, the embedded 10-character PAN, the PAN holder type (company, individual/proprietor, firm/LLP, HUF, trust, government and more, read from the PAN's 4th letter), the entity registration number, the default 'Z' slot and the check digit. A states endpoint returns the full GST state-code reference for building dropdowns and lookups. Everything is pure computation — no network call, no key, no cache — so it is fast and private, ideal for checkout and onboarding forms, invoicing and e-invoice/e-way-bill pipelines, vendor master data cleansing and bulk validation. A structural GSTIN validator and decoder — distinct from EU VAT-number validation (vat), IBAN bank-account validation (iban) and card-number checks (creditcard). Note: this verifies the number's structure and check digit, not whether it is actively registered in the GSTN portal. No upstream key, no cache.

Analítica de finanzas descentralizadas como API, impulsada por DeFiLlama — el panel independiente más utilizado para rastrear el Valor Total Bloqueado (TVL) en el ecosistema DeFi. TVL es el valor en dólares de los activos depositados en un protocolo, la medida clave del tamaño y la salud de un protocolo DeFi. Esta API envuelve los datos abiertos de DeFiLlama en JSON limpio y compacto. /v1/protocols clasifica los protocolos DeFi por TVL y te permite filtrar por blockchain (chain=Ethereum) y por categoría (category=Lending, Dexes, Liquid Staking, CDP, Yield, Bridge y más) — cada protocolo con su slug, símbolo del token, categoría, las cadenas en las que opera, su TVL en USD y el cambio de TVL en 1 día y 7 días. /v1/protocol?slug=aave devuelve el perfil de un solo protocolo y su TVL actual desglosado por blockchain (solo cadenas reales, por lo que la cifra principal no se infla con agregados de staking o préstamos). /v1/chains clasifica cada blockchain por el TVL desplegado en ella. /v1/stablecoins clasifica las stablecoins por suministro circulante, con el tipo de anclaje y el mecanismo de anclaje de cada moneda. Todos los valores están en dólares estadounidenses y reflejan la instantánea más reciente. Ideal para paneles de cripto y DeFi, herramientas de cartera y riesgo, productos de investigación de mercado y análisis, y bots de Discord/Telegram. Esto es análisis on-chain/DeFi — distinto de las fuentes de precios de tokens. Usa un slug de protocolo de /v1/protocols para el endpoint de detalle. Datos de DeFiLlama (gratuito y abierto).
