Any x402-priced endpoint now also accepts Authorization: Payment credentials from the https://tempo.xyz/install - pay-per-call with a Tempo mainnet wallet, no Nansen API key required. Same endpoints, same prices as x402 ($0.01–$7.50 USDC).

How to get started

1. Install the tempo CLI

curl -fsSL https://tempo.xyz/install | bash 

2. Create + fund a wallet (opens a browser, passkey flow — ~$1 is plenty)

"$HOME/.tempo/bin/tempo" wallet login "$HOME/.tempo/bin/tempo" wallet fund 

3. Make a paid call

"$HOME/.tempo/bin/tempo" request \ -X POST https://api.nansen.ai/api/v1/tgm/indicators \ -H 'X-Anonymous-Consumer: true' \ -H 'Authorization: Payment' \ --json '{"chain":"ethereum","token_address":"0x7fc66500c84a76ad7e9c93437bfc5ac33e2ddae9"}'
