HTTP API
An overview of the Arweave HTTP API.
The Arweave protocol is based on HTTP, so any existing http clients/libraries can be used to interface with the network, for example Axios or Fetch for JavaScript, Guzzle for PHP, etc.
The default port is 1984.
Requests and queries can be sent to any Arweave node directly using their IP address, for example http://159.65.213.43:1984/info. Hostnames can also be used if configured with DNS, for example https://arweave.net/info.
cURL
JavaScript (Fetch)
NodeJS
curl --request GET \
--url 'https://arweave.net/info'
fetch("https://arweave.net/info")
.then((response) => response.json())
.then((data) => {
console.log("Arweave network height is: " + data.height);
})
.catch((error) => {
console.error(error);
});
let request = require("request");
let options = {
method: "GET",
url: "https://arweave.net/info",
};
request(options, function (error, response, body) {
if (error) {
console.error(error);
}
console.log("Arweave network height is: " + JSON.parse(body).height);
});
Arweave specific wrappers and clients are currently in development to simplify common operations and API interactions, there are currently integrations for Go, PHP, Scala (which can also be used with Java and C#) and JavaScript/TypeScript/NodeJS.
Common data structures, formats, and processes explained.

Nodes and gateways accept transactions through the
POST /tx endpoint. The body must be a JSON encoding of a transaction. Amounts are specified in winstons.Transaction and block identifiers and wallet addresses, among some other fields, are encoded as Base64URL strings when sent over HTTP or put in the URLs or displayed in the block explorers.
Base64URL is case-sensitive.
For example,
T414mkfW-EQWEwPtk__LMJAgawNdxZfdjxhGPQKMwDQ, t414mkfW-EQWEwPtk__LMJAgawNdxZfdjxhGPQKMwDQ, and t414mkfw-eqwewptk__lmjagawndxzfdjxhgpqkmwdq are three different addresses. It is impossible to recover tokens sent to a different case of the same address.A transaction may be used for uploading data, transferring tokens, or both.
Name | Required | Serialization Format | Value |
|---|---|---|---|
format | Yes | integer | Currently supported formats are `1` and `2` (often referred to as v1 and v2 respectively). The v1 format is deprecated. |
id | Yes | Base64URL string | A SHA-256 hash of the transaction signature. |
last_tx | Yes | Base64URL string | An anchor - a protection against replay attacks. It may be either a hash of one of the last 50 blocks or the last outgoing transaction ID from the sending wallet. If this is the first transaction from the wallet then an empty string may be used. The recommended way is to use the value returned by GET /tx_anchor. Two different transactions can have the same last_tx if a block hash is used. |
owner | Yes | Base64URL string | The full RSA modulus value of the sending wallet. The modulus is the n value from the JWK. The RSA public key. |
tags | No | array of objects | A list of name-value pairs, each pair is serialized as {"name": "a BaseURL string", "value":" a Base64URL string"}. If no tags are being used then use an empty array []. The total size of the names and values may not exceed 2048 bytes. Tags might be useful for attaching a message to a transaction sent to another wallet, for example a reference number or identifier to help account for the transaction. |
target | No | Base64URL string | The target address to send tokens to (if required). If no tokens are being transferred to another wallet then use an empty string. Note that sending tokens to the owner address is not supported. The address is the SHA-256 hash of the RSA public key. |
quantity | No | Numerical string (winstons) | The amount to transfer from the owner wallet to the target wallet address (if required). |
data_root | No | Base64URL string | Only use with v2 transactions. The merkle root of the transaction data. If there is no data then use an empty string. |
data_size | No | Numerical string (bytes) | Only use with v2 transactions. The size in bytes of the transactin data. Use "0" if there is no data. The string representation of the number must not exceed 21 bytes. |
data | No | Base64URL string | The data to be submitted. If no data is being submitted then use an empty string. For v2 transactions there is no need, although it is possible, to use this field even if there is data (means, data_size > 0 and data_root is not empty). In v1 transactions, data cannot be bigger than 10 MiB. In v2 transactions, the limit is decided by the nodes. At the time this was written, all nodes in the network accept up to 12 MiB of data via this field. |
reward | Yes | Numerical string (winstons) | The transaction fee. See the price endpoint docs for more info. |
signature | Yes | Base64URL string | An RSA signature of a merkle root of the SHA-384 hashes of transaction fields (except for id, which is the hash of the signature). See Transaction Signing for more. |

Transaction signatures are generated by computing a merkle root of the SHA-384 hashes of transaction fields:
format, owner , target , data_root, data_size, quantity, reward, last_tx, tags, then signing the hash. Signatures are RSA-PSS with SHA-256 as the hashing function.Arweave uses the JSON Web Key (JWK) format (RFC 7517) with 4096 length RSA-PSS keys. This JWK format allows for cryptographic keys to be represented as a JSON object where each property represents a property of the underlying cryptographic key. It's widely supported with libraries for most popular languages. It's possible to convert a JWK to a PEM file or other crypto key file format, support for this this will vary from language to language. If you're generating your own keys manually the public exponent (e) must be 65537. If any other value is used the transactions signed by these keys will be invalid and rejected.
The
n value is the public modulus and is used as the transaction owner field, and the address of a wallet is a Base64URL encoded SHA-256 hash of the n value from the JWK.The address for this wallet is

1 AR = 1000000000000 Winston (12 zeros) and 1 Winston = 0.000000000001 AR.
The HTTP API will return all amounts as winston strings, this is to allow for easy interoperability between environments that do not accommodate arbitrary-precision arithmetic.
JavaScript for example stores all numbers as double precision floating point values and as such cannot natively express the integer number of winston. Providing these values as strings allows them to be directly loaded into most 'bignum' libraries.
Endpoints for interacting with transactions and related resources.

The quantity and reward values are always represented as winston strings.

The
Content-Type will default to the one specified in a tag with tag-name Content-Type.You can also get the data with a different
Content-Type response, by doing:get
https://arweave.net
/tx/{id}/data.{extension}
Get Transaction Data with extension
A
Content-Type tag-name can be submitted with a transaction, the tag-value will then be used as the Content-Type header when serving the data response, this allows you to submit binary files like images and have them served with correct content type headers over HTTP.The default Content-Type is application/octet-stream.

/price/{bytes}/{target}
Get Transaction Price
An extra fee is taken for the first transaction sent to a new wallet address. This is intentional and to discourage wallet spam.
To get a fee for sending 10 AR to a wallet with address
