Prompts for coding agents

Each prompt gives your coding agent the endpoints, enum values, and constraints for one Lumx task, so it builds against the API instead of guessing. Paste a prompt into Claude Code, Cursor, Codex, or any agent that can read a URL, and it reads these docs and the OpenAPI spec before writing code. Every prompt follows the same shape: the sources to read first, numbered steps with literal endpoints, constraints, and the deliverables to expect. No prompt creates an API key, so create your Sandbox key before you start. See Authentication.

​

Setup and testing

Get to a working Sandbox integration, then harden it for production.

• Lumx sandbox quickstart — Prove a deposit-to-stablecoin round trip in Sandbox.
• Connect your agent to the Lumx docs MCP — Connect your agent to these docs so it stops guessing field names.
• Set up partner fees and revenue share — Earn a fee on every transaction you route.
• Debug Lumx webhook delivery — Find out why webhooks don’t arrive or fail verification.
• Production readiness checklist — Audit a working Sandbox integration before real money moves.
• Audit an existing Lumx integration — Find what costs money or fails compliance in a live integration.

​

End-to-end integrations

Build one Lumx capability from the first call to settlement.

• Integrate customer onboarding and verification — Take a business or individual from signup to an approved customer.
• Integrate local-currency virtual accounts — Collect in local currency through accounts in your customer’s name.
• Integrate on-ramps from fiat to stablecoin — Take fiat in and deliver stablecoin to the customer’s wallet.
• Integrate off-ramps to local bank rails — Pay out from a stablecoin balance to a local bank account.
• Integrate autoconversion rules — Convert every deposit to stablecoin with a standing rule.
• Integrate webhooks with signature checks — Receive signed events that survive retries and secret rotation.
• Integrate Lumx into a Next.js app — Add Lumx to a Next.js App Router project without leaking the key.

​

Build a product

Combine several capabilities into a complete payment product.

• Build the BRL corridor end to end — Build BRL in over PIX and out again as working code.
• Build global contractor payouts — Pay contractors in several countries from one funded balance.
• Build marketplace seller payouts — Pay marketplace sellers and take a platform fee on every sale.
• Build a Lumx reconciliation ledger — Answer which transactions settled without opening a dashboard.

​

Migrate from an existing setup

Move a payment flow you already run onto Lumx.

• Migrate manual bank payouts to the Lumx API — Replace a spreadsheet and a bank portal with API payouts.
• Migrate SWIFT wires to local payout rails — Move international wires onto local payout rails.
• Migrate from one PSP per country — Collapse one payment provider per country into one integration.
