An authorisation (transferWithAuthorization or receiveWithAuthorization, EIP-3009) counts whether it is called directly or inside a batch: when the outer call is not one of the known functions, the receipt is read, and an AuthorizationUsed on the token with the payer as authorizer makes it a batched authorisation. An authorisation submitted by the payer itself is self; by a sender that landed authorisations for at least 5 different sellers in the window is facilitator; by anyone else is third_party. A plain transfer by the payer is payer_transfer; a 4337 bundle or a smart-account execute is bundler_or_smart_account. receive_share is the share of authorisations in the closed form, which binds the submitter to the payee; batched authorisations are not counted in it because the receipt does not say which of the two functions was called.","method":"afg-x402submit, daily at 04:40 UTC: eth_getLogs for the transfers, then each transaction from free public nodes, and the receipt for a transaction whose outer function is not known. third_party is the replacement front-run surface Bartoletti & Zunino (2023) and Materwala et al.
