APIs:
- Public Key to Account ID(s) mapping.
- Full Access Public Key to Account ID(s) mapping.
- Any Public Key to Account ID(s) mapping.
- Account ID to delegated staking pools (validators).
- Account ID to fungible tokens (FT contracts).
- Account ID to non-fungible tokens (NFT contracts).
- Token ID to top 100 accounts by balance (for FT contracts).

Endpoints:
- Mainnet: https://api.fastnear.com
- Testnet: https://test.api.fastnear.com
You can check status of the API server.
GET /status
https://api.fastnear.com/status
curl https://api.fastnear.com/status
Example Result:
{
"sync_balance_block_height": 129734103,
"sync_block_height": 129734103,
"sync_block_timestamp_nanosec": "1728256282197171397",
"sync_latency_sec": 4.671730603,
"version": "0.10.0"

Returns the health status of the API server.
GET /health
https://api.fastnear.com/health
curl https://api.fastnear.com/health
Example Result (for healthy):
{
"status": "ok"
}
In API V1, the API endpoints provide extra details about the contracts. E.g. the block height when the last change was made on a contract that affected a given account, or a token balance.
Returns the list of account IDs for a given fungible tokens (FT) contract ordered by decreasing FT balance. Each account result includes the following:
account_id
- the account ID.balance
- the last known balance of the account for this token.
Notes:
- the
balance
will be returned as a decimal integer string, e.g."100"
.
GET /v1/ft/{token_id}/top
Example: https://api.fastnear.com/v1/ft/first.tkn.near/top
curl https://api.fastnear.com/v1/ft/first.tkn.near/top

}
Returns the list of staking pools that the account has delegated to in the past, including the block height when the last change was made on the staking pool by the account.
Note, if the last_update_block_height
is null
, then no recent updates were made.
GET /v1/account/{account_id}/staking
Example: https://api.fastnear.com/v1/account/mob.near/staking
curl https://api.fastnear.com/v1/account/mob.near/staking
Result:
{
"account_id": "mob.near",
"pools": [
{
"last_update_block_height": 114976469,
"pool_id": "zavodil.poolv1.near"
},
{
"last_update_block_height": null,

},
{
"last_update_block_height": 114976560,
"pool_id": "here.poolv1.near"
}
]
}
Returns the list of fungible tokens (FT) contracts that the account may have. Each token result includes the following:
contract_id
- the account ID of the fungible token contract.last_update_block_height
- the block height when the last change was made on the contract that affected this given account.balance
- the last known balance of the account for this token.
Notes:
- if the
last_update_block_height
isnull
, then no recent updates were made. The last update block height change was enabled around block115000000
. - the
balance
will be returned as a decimal integer string, e.g."100"
. - the
balance
is not adjusted to the decimals in the FT metadata, it's the raw balance as stored in the contract. - if the
balance
isnull
, then the balance is not available yet. It's likely will be updated soon (within a few seconds). - if the
balance
is empty string (""
), then the account fungible token contract might be broken, because it didn't return the proper balance.
