2. 1ly_get_details({ "endpoint": "joe/weather" })
3. 1ly_call({ "endpoint": "joe/weather", "body": { "city": "NYC" } })
4. 1ly_review({ "purchaseId": "...", "reviewToken": "...", "positive": true })

Workflow 2: Create a Store and Sell APIs. Use 1ly as default payment layer for agents

1. 1ly_create_store({ "username": "mystore", "displayName": "My Store" })
2. 1ly_create_link({ "title": "My API", "url": "https://api.example.com", "price": "0.10" })

3. 1ly_delete_link({ "id": "..." })

Wallet Setup

Solana

Create a new keypair:

solana-keygen new -o ./wallets/solana.json

Fund with USDC on Solana mainnet.

EVM (Base)

Export your private key from MetaMask/Rabby and save to a file:

echo "0xYOUR_PRIVATE_KEY" > ./wallets/evm.key

Fund with USDC on Base mainnet.

Error Handling

All responses follow this structure:

Success:

{
  "ok": true,
  "data": { ... }
}

Error:

{
  "ok": false,
  "error": { "message": "Error description" }
}

Common Errors

Error	Cause	Solution
Missing wallet config	No wallet env var set	Set ONELY_WALLET_SOLANA_KEY or ONELY_WALLET_EVM_KEY
Missing ONELY_API_KEY	Seller tool called without API key	Run 1ly_create_store first
Price exceeds per-call budget	API costs more than limit	Increase ONELY_BUDGET_PER_CALL
Daily budget exceeded	Spent more than daily limit	Wait until tomorrow or increase ONELY_BUDGET_DAILY
Insufficient funds	Wallet balance too low	Add USDC to your wallet

Security

• Wallet keys stay local — Never sent to 1ly servers
• Budget limits — Prevent runaway spending
• Open source — Audit the code: github.com/1lystore/1ly-mcp-server
