Quickstart

Buy credits, deposit them, create a key and send your first request.

You need a Solana wallet (Phantom, Solflare, Backpack or any other Wallet Standard wallet) with USDC or another token you can swap, and a little SOL for network fees.

1. Buy credits

Open /app/buy, connect your wallet and enter an amount. One credit costs 1 USDC. If you pay with another token, it is swapped to USDC through Jupiter in the same transaction.

By default the credits go straight to your API balance. Turn on Keep in wallet to receive them as tokens instead and deposit them later on /app/balance.

2. Create an API key

Open /app/keys and create a key. It is shown once, so copy it before closing the dialog.

bash

export UNSPENT_API_KEY=usp_live_...

3. Send a request

bash

curl https://api.egrtgghfghtytgb.space/v1/messages \
  -H "x-api-key: $UNSPENT_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
  -H "content-type: application/json" \
  -d '{"model":"claude-sonnet-5-5","max_tokens":512,
       "messages":[{"role":"user","content":"Hello"}]}'

With the Anthropic SDK:

python

import os
from anthropic import Anthropic

client = Anthropic(base_url="https://api.egrtgghfghtytgb.space", api_key=os.environ["UNSPENT_API_KEY"])
message = client.messages.create(
    model="claude-sonnet-5-5",
    max_tokens=512,
    messages=[{"role": "user", "content": "Hello"}],
)
print(message.content[0].text)

With the OpenAI SDK:

import OpenAI from "openai";

const client = new OpenAI({ baseURL: "https://api.egrtgghfghtytgb.space/v1", apiKey: process.env.UNSPENT_API_KEY });
const completion = await client.chat.completions.create({
  model: "claude-sonnet-5-5",
  max_tokens: 512,
  messages: [{ role: "user", content: "Hello" }],
});
console.log(completion.choices[0].message.content);

Using Claude Code? Two environment variables are enough: see Claude Code.

4. See what it cost

Every request is listed on /app/usage with its tokens, its cost and the two Solana transactions that held and settled it. Your balance is on /app/balance and at GET /v1/balance:

bash

curl https://api.egrtgghfghtytgb.space/v1/balance -H "x-api-key: $UNSPENT_API_KEY"

json

{ "available": "24.98965", "reserved": "0", "balance": "24.98965" }
