Let your agents
do the work.
You set the limits.
One connection to paid APIs. Smart routing, controlled spending, and a receipt for every request.
Built for agents. Accountable to you.
Your agent's next capability is already out there.
Discover providers across Pay.sh, Circle, PayAI & Coinbase's x402 Bazaar. Provider names belong to their owners.Autonomy looks better
with a little oversight.
See what your agents spend, where requests go, and why a payment was allowed. All in one workspace.
Take it for a spinEverything, under control.
A little autonomy. A lot of visibility.

Stay in control.
Give your agents room to work. Keep the decisions that matter in your hands.
The right API.
At the right price.
Compare real quotes. Skip providers that are down or overcharge. Route by cost, speed, or both.
Set the budget.
Keep the keys.

The details behind the autonomy.
Algebra routes an agent's request to a paid API, checks the spending rules you set, pays in USDC on Solana, verifies the result, and returns a signed receipt. Your agent asks for a capability, such as web search or a token price, rather than managing providers and payments itself.
Your agent receives a Spend Pass with limited authority. Algebra holds the wallet key and enforces the pass's budget, per-call ceiling, provider rules and velocity limits on the server, before a payment can move.
Yes. The interactive demo uses illustrative data and simulated requests. The local economic sandbox also runs the full execution flow with simulated USDC. Real devnet payments require a configured, funded wallet.
Connect agents through REST or the MCP server. Claude, Cursor, the OpenAI Agents SDK, and any HTTP client can use Algebra with a Spend Pass. The Connect page in your console includes setup snippets.
Algebra coordinates every request through reservation, authorization, execution and reconciliation. Ambiguous outcomes are frozen until settlement evidence is checked. Every outcome receives a signed receipt you can verify independently.
Give your agent
a little independence.
And yourself a lot more peace of mind.
