The problem with API access for AI agents

Building AI agents that call external APIs is painful. For every provider, you need to create an account, manage API keys, handle billing, and track usage separately. If your agent uses OpenAI, Anthropic, a search API, a data provider, and a code execution service, that's five separate accounts to manage — and five separate bills.

How Locus solves it

Locus offers pay-per-use agent tools across 3337 provider groups behind a single payment layer. Your agent connects through hosted MCP with OAuth or a supported API credential, discovers an enabled operation, and pays from prepaid credits. The Free plan has no monthly subscription; optional plans add included credits and workspace features.

Also available via MPP

Many Locus endpoints are also available via the Machine Payments Protocol (MPP) — the open standard for machine-to-machine payments via HTTP 402. Agents with a Tempo wallet can call APIs directly and pay per request without needing a Locus account. Browse available MPP endpoints at mpp.sh/services.

Why pay-per-use beats subscriptions

  • •No wasted credits — Only pay for calls you actually make. The Free plan has no monthly subscription. Paid plans include monthly credits that expire each billing period; purchased top-ups are separate.
  • •One bill — Locus Pro tool usage is charged to the applicable credit balance. No juggling payment methods across providers.
  • •Instant access — No signup flows per provider. Connect your Locus API key and start using agent tools immediately.
  • •Budget controls — Use account spend caps, supported connection limits, and tool permissions. Alerts and auto-reload settings are separate controls; work already accepted can still be charged.

Connect and control usage

Locus Pro uses prepaid credits. Start with the agent connection guide, review current plans, and configure spending controls before scaling a workflow. Pay With Locus is the separate on-chain wallet product.
