Environment / auth

PRIVATE_KEY
secret
Ethereum private key for write/buy tools (subscribe, unsubscribe, publish, buy_data). buy_data spends real Base-mainnet USDC — use a dedicated wallet. Not required for read-only tools.
RPC_URL
RPC for the on-chain library + EIP-712 attestation layer (Arbitrum Sepolia, eip155:421614). The x402 buy rail settles USDC on Base mainnet and needs no RPC here. Defaults to Arbitrum Sepolia public RPC.
BYTE_GATEWAY_ATTESTER
Gateway attester address byte_buy_data pins receipts against. Defaults to the current PayPerByte gateway attester (rotated 2026-08-19; previous default 0x77c86a...C472 is retired). Override only if the gateway discloses a rotation you need ahead of a package update - see /.well-known/agent.json receipt.attester and receipt.retiredAttesters.
