{"openapi":"3.1.0","info":{"title":"Token Approval Security API","version":"1.0.0","description":"Live audit of the token approvals (allowances) a crypto wallet has granted, and the risk of the contracts it has approved to spend its tokens — powered by the public GoPlus Security data, no key, nothing stored. Token approvals are the single most common way wallets get drained: once you approve a contract to move a token, a malicious or compromised spender can take it whenever it likes. This is the allowance-hygiene layer — the data behind tools like revoke.cash. The approvals endpoint lists every token a wallet has approved, who it approved (the spender contract), how much was approved and when, and whether that spender is flagged as malicious, trusted or unverified, together with a risk summary counting the dangerous approvals to revoke. The contract endpoint profiles a single spender contract before you approve it — its name, whether it is open-source, its creator, deploy time and risk tags. The chains endpoint lists the 40-plus supported blockchains. Catch wallet-draining allowances before they cost a user everything. This is the approval / allowance-risk cut — distinct from the token-contract-security, scam-detection and on-chain APIs in the catalogue.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/approvalsecurity-api","description":"oanor gateway"}],"tags":[{"name":"Approvals"},{"name":"Contract"},{"name":"Chains"},{"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/approvals":{"get":{"operationId":"get_v1_approvals","tags":["Approvals"],"summary":"A wallet token approvals with spender risk","description":"","parameters":[{"name":"address","in":"query","required":true,"description":"Wallet address","schema":{"type":"string"},"example":"0x28c6c06298d514db089934071355e5743bf21d60"},{"name":"chain","in":"query","required":false,"description":"GoPlus chain id (default 1=Ethereum)","schema":{"type":"string"},"example":"1"}],"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/contract":{"get":{"operationId":"get_v1_contract","tags":["Contract"],"summary":"A spender contract risk profile","description":"","parameters":[{"name":"contract","in":"query","required":true,"description":"Spender contract address","schema":{"type":"string"},"example":"0x1111111254eeb25477b68fb85ed929f73a960582"},{"name":"chain","in":"query","required":false,"description":"GoPlus chain id (default 1)","schema":{"type":"string"},"example":"1"}],"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/chains":{"get":{"operationId":"get_v1_chains","tags":["Chains"],"summary":"Supported blockchains","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":12000,"rps_limit":3,"hard_limit":true},{"slug":"builder","name":"Builder","price_cents_month":955,"monthly_call_quota":170000,"rps_limit":10,"hard_limit":true},{"slug":"pro","name":"Pro","price_cents_month":2790,"monthly_call_quota":760000,"rps_limit":28,"hard_limit":true},{"slug":"scale","name":"Scale","price_cents_month":6240,"monthly_call_quota":2700000,"rps_limit":65,"hard_limit":true}],"x-oanor-marketplace-url":"https://www.oanor.com/api/approvalsecurity-api"}
