This is an invitation, not a guaranteed bounty.
Offer a post only after Keryx judges its public RSS preview relevant. Once the source is registered, indexed, and ownership-verified, Keryx sponsors one bounded retry with at most $0.05 on Arc testnet. A payout happens only when the paid full text supplies qualifying evidence, the agent cites it, and Circle settlement succeeds.
Already listed? Offer the exact article.
Keryx rechecks your registry authority and public preview, then guarantees this version a place in the retry. The agent still decides BUY or SKIP; only grounded, settled evidence fills the claim.
The agent sees your recent titles and summaries — the same free preview a listed source gets judged on. Takes a few seconds.
“The ephemeral nature of session keys allows for shorter-lived credentials that limit the window of exposure, yet it introduces tradeoffs such as difficulty in key recovery and potential denial of access if the session is lost before expected.”
