Dataline raises $10.6M to expand AI agent data marketplace

Dataline has raised $10.6 million to expand a decentralized marketplace where data publishers sell feeds to AI agents and get paid per API call, PYMNTS reported. The round was co-led by Lattice and Samsung-backed Dispersion Capital, with Symbolic Capital participating.

Responses carry an AI confidence score calculated from source reliability, freshness and consistency, with agents paying through the x402 protocol. The company says the system has powered 19.4 million on-chain transactions and that its community spans more than 300,000 members globally.

"After building AI agents ourselves, we realized that clean and reliable data is the lifeblood of AI," co-founder Nuo Shi said. Builders on Base and Robinhood Chain are getting complimentary access through a Launch Partners cohort, receiving API calls embedded with AI-graded confidence scores for normalized market data. The deal lands in a busy stretch for agent-infrastructure funding in our tracker over the past three months.
