AI agents querying on-chain data without per-provider API accounts — is anyone solving this cleanly?

Building an agent that needs live on-chain data (mempool, pool states, DEX volume, holder counts) exposes a workflow problem that does not get discussed much.

Every data provider wants a separate account, a separate API key, and a separate billing setup. Your agent ends up juggling providers for RPC, wallet data, analytics, and market feeds. Each one is a subscription, a key to rotate, a rate limit to track.

For a human developer this is annoying. For an autonomous agent running in production this is a structural problem. You cannot ask the agent to sign up for accounts, manage keys securely, or handle per-provider billing without building a lot of scaffolding that has nothing to do with your actual strategy.

The pattern that makes more sense for agents: single endpoint, pay-per-call, no account required. The agent queries what it needs, pays in stablecoins per call, no key management, no subscriptions, no vendor lock-in.

Is anyone building infrastructure like this or working around it differently? Curious what setups people are actually running for on-chain data in production agent pipelines.
