Agents
Expose an x402 endpoint for portable payment intents while policy guardrails keep execution predictable.
- x402 endpoint
- Payment guardrails
- Bounded approvals
For developers & builders
Open infrastructure for programmable commerce.
Fluent publishes portable on-chain payment intents that wallets, applications, agents and routing protocols can fulfil without Fluent taking custody.

Predictable payments for applications, agents, and protocols.
API access
Connect software operators through scoped API keys and explicit, auditable commerce actions.
- Scoped API keys
- Explicit intents
- Auditable outcomes
Integrations
Connect multiple apps and services. Merchants can set up as many endpoints as they need to receive funds directly into their own accounts.
- Multiple endpoints
- Direct receipt
- Merchant-controlled routing
Mandates
Give a contract or delegate bounded permission, then let application logic execute recurring or metered charges.
- Defined allowance
- Scheduled execution
- Self-custodial control
Mandates & recurring
A chain-unified, self-custodial recurring commerce protocol.
Give a contract or delegate permission to spend up to a defined amount, then let application logic execute charges on schedule.
Control stays explicit
Bounded permission, direct settlement, and verifiable proof preserve the buyer and merchant relationship.
