Pricing

Free to build on. Pay when your agents do real work.

Every plan includes the whole spend firewall. Plans differ in how many projects and on-chain executions they cover. Sandbox runs are free and unlimited on all of them.

Paid plans can't be bought online yet. There is no checkout here: no payment processor is connected for these plans. Free and the seven-day Startup trial work today, with no card. For a paid plan, talk to us.

The seven-day Startup trial

  • Start it from Projects & API keys in the console. Owners and admins only.
  • No card is asked for and nothing is charged.
  • For seven days your organization has the Startup plan's limits.
  • When it ends you are back on Free automatically. Nothing is deleted; projects beyond the Free limit stay, and you can't add more until you archive one or change plan.
  • One trial per organization.

What you pay, and to whom

Algebra's fee
The plan price above. Nothing is added to a provider's price.
Provider charges
What each paid API asks per call, in USDC, paid from your own Spend Pass straight to the provider. The receipt shows the exact amount and the transaction.
Network fees
Solana transaction fees. For x402 calls the provider's facilitator pays them. An on-chain Spend Pass adds a small fee per pull.

Algebra never pays a provider for you: a free plan does not include free paid APIs.

On every plan

  • Spend Passes: budget, per-call cap, approval line, allowed providers, calls per minute
  • Kill switch, and the rule for providers never paid before
  • Dry runs: ask what would happen without paying
  • Provider guards: down, over its own listing, trap-priced, payee changed
  • A signed receipt for every outcome, verifiable by anyone
  • REST API and MCP server, with scoped API keys per environment
  • Unlimited sandbox runs, never counted

"On-chain executions" are committed paid requests on Solana devnet or mainnet. Mainnet payments are switched off on this deployment until the mainnet safety checks are complete; discovery, quotes and dry runs against mainnet providers work today.

Two things are not built yet, so no plan sells them: inviting other people into an organization, and stopping requests at a plan's monthly execution allowance. Usage is counted and shown per project today; the project limit is enforced.
