Summary
A "NEAR check" usually means one of three things: confirming a transaction or account on the NEAR blockchain, verifying that your RPC endpoint is responding correctly, or validating a wallet or contract interaction before you ship. The fastest path is to use a block explorer for human-readable lookups and a JSON-RPC call for programmatic checks.
This page gives you the practical checks developers run most often on NEAR: reading an account balance, fetching a transaction outcome, confirming block height, and probing an RPC endpoint for health. It also explains when a public endpoint is enough and when you should move to a dedicated RPC provider such as OnFinality for consistent access.
NEAR uses a JSON-RPC interface with methods like query, block, and tx. The examples below show how to run those checks with curl and with JavaScript, and how to interpret the responses so you can tell the difference between a network issue, an RPC issue, and an application bug.
Key Takeaways
- A NEAR check can mean a transaction lookup, an account balance read, or an RPC health probe; each uses a different method.
- NEAR JSON-RPC methods such as
query,block, andtxcover most verification needs without a custom indexer. - Explorers are best for human-readable lookups; JSON-RPC is better for automated checks in CI, monitoring, or backend services.
- Distinguish between a failed transaction, a lagging RPC node, and a malformed request by checking the response shape and block height.
- Public endpoints are fine for development and low-volume checks; production checks usually need a dedicated RPC provider with predictable access.
- OnFinality provides NEAR RPC API access and dedicated node options; check the supported networks page for current availability.
Which NEAR check do you actually need?
Before you write a request, decide what you are verifying. Most "NEAR check" tasks fall into four buckets: confirming a transaction outcome, reading an account or contract state, checking that an RPC endpoint is healthy, and validating a wallet or dApp connection. Each has a different method and a different failure mode.
Use the table below to pick the right tool. If you need a human-readable view, an explorer is faster. If you need to automate the check, JSON-RPC is the right layer.
| Criterion | What to check | Why it matters |
|---|---|---|
| Transaction outcome | Transaction hash, final execution status, and whether the failure is in the transaction or receipt | A transaction can be included in a block but still fail during execution; checking only inclusion gives a false positive |
| Account balance | Account ID, available balance, staked balance, and storage usage | NEAR accounts hold liquid and staked balances separately; a balance check that ignores storage or staking can mislead |
| RPC health | Latest block height, response time, and error rate across repeated calls | A node that responds but lags behind the chain will return stale state and break checks silently |
| Wallet or dApp connection | Network ID, account access keys, and whether the wallet is pointed at mainnet or testnet | Most "failed" checks in development are network mismatches, not chain errors |
NEAR JSON-RPC checks with curl
NEAR exposes a JSON-RPC interface. The exact endpoint depends on the provider and network. For production or repeated checks, use an endpoint from a provider you trust and keep it in an environment variable rather than hard-coding it.
The example below shows the request shape for a block height check. Replace the endpoint with your provider's NEAR RPC URL. If you are evaluating OnFinality, confirm the current NEAR endpoint and network support on the supported networks page before you build around it.
- Use
blockwithfinality: "final"to get a recent finalized block and confirm the node is following the chain. - Use
querywithrequest_type: "view_account"to read an account balance. - Use
txwith the transaction hash and sender account ID to fetch a transaction outcome. - Keep the JSON-RPC
idfield unique per request so you can correlate responses in logs.
Reading a NEAR transaction result correctly
A NEAR transaction response contains more than a success flag. The top-level status describes the transaction itself, while transaction_outcome and receipts_outcome describe execution. A transaction can be valid and included while one of its receipts fails.
When you build a check, inspect the receipt outcomes for failure statuses rather than trusting the top-level result alone. This is the most common source of false "success" reports in NEAR integrations.
| Criterion | What to check | Why it matters |
|---|---|---|
| Top-level status | Whether the transaction was included and accepted | Tells you the transaction reached the chain, not that its effects succeeded |
| Receipt outcomes | Each receipt's status and any failure reason | Cross-contract calls can fail after the transaction is accepted |
| Logs | Execution logs for panic messages or contract-level errors | Logs often contain the actual reason a check failed |
| Block finality | Whether the block is final or optimistic | Optimistic results can change; final results are safer for settlement checks |
Probing NEAR RPC health from a script
If your check is really about whether an endpoint is usable, probe it the way your application will use it. A simple block height call repeated over time reveals lag, timeouts, and intermittent errors better than a single request.
Run the probe from the same region and network path as your application. A check that passes from your laptop but fails from your production environment usually points to network egress, DNS, or provider-side access rules rather than the NEAR chain itself.
- Record the latest block height and compare it to a second provider or explorer to detect lag.
- Track error codes separately from timeouts; they indicate different problems.
- Probe both read methods you depend on, such as
queryandblock, not just one. - Alert on sustained failure rather than a single missed request to avoid noise.
When a public NEAR endpoint is enough, and when it is not
Public endpoints are useful for learning, one-off checks, and early development. They are shared, so behavior can vary with load, and they may not support every method or historical query you need.
Move to a dedicated or managed RPC provider when checks are part of a production workflow, when you need consistent access during traffic spikes, or when you need archive data for historical verification. OnFinality provides RPC API access and dedicated node infrastructure; review the supported networks page to confirm NEAR availability and the pricing page to map request volume to a plan.
| Criterion | What to check | Why it matters |
|---|---|---|
| Development and one-off checks | Public endpoint availability and method coverage | Low volume rarely justifies dedicated infrastructure |
| Automated production checks | Predictable access, failover, and monitoring | Shared endpoints can introduce variable latency and rate limits |
| Historical verification | Archive data availability for older blocks and transactions | Pruned nodes cannot answer historical queries |
| High-frequency probing | Request limits and isolation from other workloads | Health probes should not compete with user traffic for capacity |
Debug path for failed NEAR checks
When a NEAR check fails, work from the outside in: confirm the network, confirm the endpoint, confirm the request, then confirm the result interpretation. Most failures are resolved at one of these four steps.
| Criterion | What to check | Why it matters |
|---|---|---|
| Network mismatch | Mainnet vs testnet in endpoint and wallet configuration | Accounts and transactions do not exist across networks |
| Malformed request | JSON-RPC method name, parameter types, and required fields | NEAR returns structured errors for invalid params that are easy to miss |
| Stale node | Latest block height compared to a reference | A lagging node returns old state and makes valid transactions look missing |
| Result misinterpretation | Receipt outcomes and logs, not just top-level status | Accepted transactions can still fail during execution |
Frequently Asked Questions
What does "NEAR check" mean?
It usually refers to verifying something on the NEAR blockchain: a transaction, an account balance, a contract state, or the health of an RPC endpoint. The right method depends on what you are checking.
How do I check a NEAR transaction?
Use a NEAR block explorer for a human-readable view, or call the tx JSON-RPC method with the transaction hash and sender account ID. Inspect receipt outcomes, not just the top-level status.
How do I check a NEAR account balance?
Call the query method with request_type: "view_account" and the account ID. The response includes liquid balance, staked balance, and storage usage, which you should read together.
Can I check NEAR RPC health with a simple request?
A single block call confirms the endpoint responds, but repeated probes over time are better for detecting lag and intermittent errors. Compare block height against a second source.
Do I need a dedicated RPC provider for NEAR checks?
Not for development or occasional checks. For production workflows, high-frequency probing, or historical verification, a managed or dedicated RPC provider gives more predictable access. Check OnFinality's supported networks and pricing pages for current options.
