NEAR Account Check is a paid API for AI agents from 402.com.tr, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).
Inspects a NEAR account to reveal its type, NEAR balance breakdown, contract/token status, and full-access/function-call key authorizations — live from the NEAR RPC.

How this service works
Before an agent pays or trusts a NEAR account: does it exist, what kind is it (named, implicit, 0x), how much NEAR it holds (available, staked, locked for storage), whether it is a contract or a NEP-141 token, and who controls it — full-access keys that can do anything, and function-call keys limited to one contract. Flags a wallet held by one key, a contract replaceable by key, and an account no one can sign for. Live from the NEAR RPC.
Output
Returns the account's existence status, account type (named, implicit, or 0x-style), available/staked/storage-locked NEAR balances, whether it is a deployed contract, whether it implements NEP-141, a list of full-access keys and function-call keys (with their permitted contracts), and security flags such as single-key wallet, key-replaceable contract, or keyless/locked account.
Example use cases
Pre-payment NEAR account verification
“I'm about to pay bob.near 50 NEAR — can you first check that the account exists, confirm it's a regular wallet and not some contract, and tell me who has full-access keys so I know it's not compromised?”
Smart contract security audit
“Can you pull up the account details for token.v2.ref-finance.near and tell me if it's a contract, whether it's a NEP-141 token, and whether any full-access keys could replace it?”
Implicit account trustworthiness check
“I received a payment request from a1b2c3d4e5f6a1b2c3d4e5f6a1b2c3d4e5f6a1b2c3d4e5f6a1b2c3d4e5f6a1b2.near — check if that implicit account exists, what its available NEAR balance is, and how many keys control it.”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/near-account?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive, single-call pre-flight check on a NEAR account before executing a payment, establishing trust, or auditing key authority. Prefer it over manual RPC calls when you need balance breakdown (available vs staked vs storage-locked), contract detection, and key enumeration in one response without assembling multiple NEAR RPC queries yourself.
Side effects
- Account does not exist on NEAR mainnet — returns not-found flag
- Invalid account ID format — query rejected
- NEAR RPC node unavailable — timeout or 503 error
- Rate limit exceeded — 429 response
