xAI reprices X Search by returned data

xAI is replacing X Search’s flat call pricing with $5 per 1,000 posts and $10 per 1,000 user profiles starting September 21 at noon Pacific, according to its X Search pricing notice. Every returned post—including parent and quoted posts—and every user profile counts toward billing, so thread-heavy or identity-enrichment queries can multiply cost while request counts stay flat. Builders using X as an agent-research source should recalculate unit economics and set result caps, extending the archive’s agent-search cost benchmark.
