How it works

The Attestra agent sells two calls: verify a claim (with a light client proof) and check an agent (identity, reviews, delegations).

Without payment it answers 402 with a PAYMENT-REQUIRED header. The client signs a NEP-366 delegate action holding one ft_transfer and repeats the call; the agent checks it, submits it on chain from its own account (paying the gas) and only then answers. The payer needs the token, not NEAR.

Testnet uses the free test token; mainnet uses USDC. Signing a delegate action needs a key you hold: use a passkey account here, or the CLI.
