Use cases

What agents build on top of CodeSpar.

Ten patterns early builders are shipping today, organized by the money movement they run: commerce, procurement, payroll, treasury and cross-border. Each one is a short composition of the same primitives: sessions, mandates, routing, audit.

Accounts payable agent

Invoice to paid to reconciled, without the approval inbox

The buying agent ingests supplier invoices, validates the counterparty, matches each one against the ERP, schedules Pix or boleto for the due date, and pays under a signed budget mandate. Everything closes back reconciled with the NF-e attached.

Commerce

Autonomous fulfillment agentEnd-to-end order handling for LatAm marketplacesAn agent watches the order stream, charges the buyer on the cheapest local rail, issues the fiscal document, prints a shipping label, notifies on WhatsApp, and reconciles it all into the ERP. Unattended, audit-sealed.58sfrom order to sealed ledgerSee example WhatsApp commerce botConversational checkout that settles in chatCustomer browses, negotiates, and pays without leaving WhatsApp. The agent generates a Pix QR inline, confirms payment, issues the fiscal doc, and sends tracking once the carrier picks up. No links, no redirects.3-tapcheckout inside chatSee example Subscription billing agentMulti-currency charges with local railsCharge $10 USD equivalent in each customer's local currency, on the rail they prefer, with the right fiscal doc. Handles dunning, retries, downgrades, and mid-cycle changes without a human touching the payments.12 currenciesfrom one base priceSee example Support refund agentTicket to refund in under a minuteThe agent reads the complaint, verifies the order against the ERP, refunds on the original rail, issues the credit note, and notifies the customer. Policy-checked against per-agent spend limits. Every step sealed.12scomplaint to refund + auditSee example

Procurement / AP

Fiscal compliance autopilotNF-e, CFDI, Factura issued automaticallyEvery transaction triggers the right fiscal document in the right country. The agent validates CNPJ/RFC/CUIT, emits the document, stores the PDF + XML, and registers in the ERP. No more end-of-month fiscal panic.100%auto-issued on transactionSee example Multi-country ERP bridgeOne source of truth across Omie, Bling, SAPAgents write every transaction to the right ERP per country and entity. Currency-converted, fiscal-attached, counterparty-matched. The accounting team wakes up to a reconciled ledger, not a reconciliation to-do.Zeromanual reconciliation entriesSee example

Payroll + payouts

Contractor payroll agentThe monthly payout run, inside caps, on PixThe agent reads the approved contractor list, validates every payee's key and tax ID, and pays the run over Pix inside a payroll mandate with a monthly cap. Each payout gets its own receipt; the run closes reconciled to the ERP.1 intentthe whole run, sealedSee example

Treasury

Treasury agentIdle balance managed by policyThe agent watches wallet balances across currency slots, keeps the operating float liquid, and moves the rest between BRL and USDC slots under the same mandate. One wallet, per-currency caps, every move sealed.1 walletBRL + USDC slots, no FX deskSee example Auto top-upThe float refills itselfWhen the BRL slot drops below the floor, the agent mints a dynamic Pix charge against the funding source and tops the wallet up, under the same mandate, inside the same caps. Payouts never stall at 2am because the float ran dry.0 stallsfloat keeps itself liquidSee example Machine spend (x402)Pay-per-call APIs in USDCAn x402-priced API answers with a quote; the agent settles it in USDC from its wallet slot, inside the per-tx cap, and the receipt is sealed with the mandate that allowed it. Machine-to-machine spend with a budget, not a blank check.1 USDCspent per call, sealed with the mandateSee example

Cross-border

Cross-border payout orchestratorPay sellers, contractors, suppliers in local currencyRoute payouts to BR, MX, AR, and CO using the cheapest rail per destination. USDC when it's cheapest, Pix/SPEI/Transferencias when it's faster. Every transfer mandate-signed and ledgered.$56 savedper $2k cross-border transferSee example
