Social Intel API uses the x402 protocol for payment. Instead of API keys or subscriptions, you pay per request in USDC. Your x402 client library handles payment automatically.Documentation Index

How it works
- You send a request to the API
- The API responds with HTTP 402 and payment details
- Your x402 client automatically pays the specified USDC amount
- The client retries the request with a payment proof header
- The API verifies payment on-chain and returns results
Supported chains
| Chain | Asset | Network |
|---|---|---|
| Base | USDC | Mainnet |
| Solana | USDC | Mainnet |
Wallet setup
You need a wallet with USDC on Base or Solana. Each request costs 0.26 plus ~$0.001 in gas.Base (EVM) — fastest path
Option A: Buy USDC directly on Base- Create a Coinbase account (or use Coinbase Wallet)
- Buy USDC and select Base network at checkout — no bridging needed
- Export your private key from MetaMask/Coinbase Wallet
- Pass it to your x402 client
- Have USDC on Ethereum mainnet
- Bridge to Base via bridge.base.org
Keep at least 0.001 in gas.
Solana
- Get a Solana wallet private key (base58 format)
- Buy USDC on Solana via Coinbase or Jupiter
- Pass the private key to your x402 client
Dynamic pricing
The price depends on how many results you request:limit | Price |
|---|---|
| 1-20 | $0.10 |
| 50 | $0.16 |
| 100 | $0.26 |
price = $0.10 + max(0, limit - 20) * $0.002
The price is included in the 402 response headers, so your client always knows the exact cost before paying.
