{"openapi":"3.1.0","info":{"title":"TON Blockchain API","version":"1.0.0","description":"Live on-chain data from The Open Network (TON / Toncoin), the layer-1 blockchain integrated with Telegram — no key, nothing cached, nothing stored. The network endpoint returns the latest masterchain block (the chain tip). The account endpoint returns any TON address's balance (in TON and nanoTON), account state and last-transaction reference. The transactions endpoint returns an address's most recent transactions with counterparties, value, fee and time. Addresses accept raw (0:.. / -1:..) or user-friendly (EQ.. / UQ..) form. This is live blockchain and network data straight from the public TON node API — distinct from the exchange-ticker, price and market APIs in the catalogue. Built for TON wallets, explorers, dashboards and on-chain analytics.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/ton-api","description":"oanor gateway"}],"tags":[{"name":"Account"},{"name":"Transactions"},{"name":"Network"},{"name":"Meta"}],"components":{"securitySchemes":{"oanorKey":{"type":"apiKey","in":"header","name":"x-oanor-key","description":"Get your key at https://www.oanor.com/developer/keys"}}},"security":[{"oanorKey":[]}],"paths":{"/v1/account":{"get":{"operationId":"get_v1_account","tags":["Account"],"summary":"Balance, state and last transaction for an address","description":"","parameters":[{"name":"address","in":"query","required":true,"description":"TON address (raw 0:../-1:.. or EQ../UQ..)","schema":{"type":"string"},"example":"-1:5555555555555555555555555555555555555555555555555555555555555555"}],"security":[{"oanorKey":[]}],"responses":{"200":{"description":"OK"},"401":{"description":"Missing or invalid x-oanor-key header"},"402":{"description":"Active subscription required"},"429":{"description":"Rate-limit or monthly quota reached"},"502":{"description":"Upstream did not respond"}}}},"/v1/transactions":{"get":{"operationId":"get_v1_transactions","tags":["Transactions"],"summary":"Recent transactions for an address","description":"","parameters":[{"name":"address","in":"query","required":true,"description":"TON address","schema":{"type":"string"},"example":"-1:3333333333333333333333333333333333333333333333333333333333333333"},{"name":"limit","in":"query","required":false,"description":"Max results (1-50)","schema":{"type":"string"},"example":"10"}],"security":[{"oanorKey":[]}],"responses":{"200":{"description":"OK"},"401":{"description":"Missing or invalid x-oanor-key header"},"402":{"description":"Active subscription required"},"429":{"description":"Rate-limit or monthly quota reached"},"502":{"description":"Upstream did not respond"}}}},"/v1/network":{"get":{"operationId":"get_v1_network","tags":["Network"],"summary":"Latest TON masterchain block (chain tip)","description":"","parameters":[],"security":[{"oanorKey":[]}],"responses":{"200":{"description":"OK"},"401":{"description":"Missing or invalid x-oanor-key header"},"402":{"description":"Active subscription required"},"429":{"description":"Rate-limit or monthly quota reached"},"502":{"description":"Upstream did not respond"}}}},"/v1/meta":{"get":{"operationId":"get_v1_meta","tags":["Meta"],"summary":"Service metadata","description":"","parameters":[],"security":[{"oanorKey":[]}],"responses":{"200":{"description":"OK"},"401":{"description":"Missing or invalid x-oanor-key header"},"402":{"description":"Active subscription required"},"429":{"description":"Rate-limit or monthly quota reached"},"502":{"description":"Upstream did not respond"}}}}},"x-oanor-pricing":[{"slug":"free","name":"Free","price_cents_month":0,"monthly_call_quota":20000,"rps_limit":3,"hard_limit":true},{"slug":"starter","name":"Starter","price_cents_month":885,"monthly_call_quota":265000,"rps_limit":10,"hard_limit":true},{"slug":"growth","name":"Growth","price_cents_month":2485,"monthly_call_quota":1225000,"rps_limit":25,"hard_limit":true},{"slug":"scale","name":"Scale","price_cents_month":5810,"monthly_call_quota":4380000,"rps_limit":50,"hard_limit":true}],"x-oanor-marketplace-url":"https://www.oanor.com/api/ton-api"}
