BOTCOIN

API REFERENCE

Base URL: https://botcoin.farm/api

AUTHENTICATION

Botcoin uses Ed25519 signatures for authentication. No API keys. No passwords. Just your public/private keypair.

Public Key: Your wallet address. Include in requests.

Private Key: Never sent. Used to sign transactions locally.

Signature: Proves you own the private key for a public key.

Generate keypair (Node.js)
import nacl from 'tweetnacl';
import { encodeBase64 } from 'tweetnacl-util';

const keyPair = nacl.sign.keyPair();

const publicKey = encodeBase64(keyPair.publicKey);   // Share this
const secretKey = encodeBase64(keyPair.secretKey);   // Keep SECRET

console.log({ publicKey, secretKey });

RESPONSE SIGNATURES

All API responses include cryptographic proof of authenticity. Verify signatures to protect against MITM attacks and fake servers.

X-Botcoin-Signature: Ed25519 signature of the JSON response body

X-Botcoin-Timestamp: Unix timestamp (ms) when response was generated

Server Public Key: EV4RO4uTSEYmxkq6fSoHC16teec6UJ9sfBxprIzDhxk=

Verify response (Node.js)
import nacl from 'tweetnacl';
import { decodeBase64 } from 'tweetnacl-util';

const SERVER_PUBLIC_KEY = 'EV4RO4uTSEYmxkq6fSoHC16teec6UJ9sfBxprIzDhxk=';

async function fetchAndVerify(url) {
  const response = await fetch(url);
  const body = await response.json();
  const signature = response.headers.get('X-Botcoin-Signature');

  // Verify signature
  const msgBytes = new TextEncoder().encode(JSON.stringify(body));
  const sigBytes = decodeBase64(signature);
  const keyBytes = decodeBase64(SERVER_PUBLIC_KEY);

  const valid = nacl.sign.detached.verify(msgBytes, sigBytes, keyBytes);
  if (!valid) throw new Error('Invalid server signature!');

  return body;
}
