Brazilian core-banking infrastructure (BaaS). Processes ~10% of Brazil's Pix per vendor case studies. Not a PSP — the rails underneath fintechs. For companies building on top of Pix rather than accepting it as a merchant. Alpha release on npm — endpoint paths pending doc verification.
Matera gives your agent 22 tools it calls directly — pick the ones it needs, in Claude, Cursor, or any MCP client.
create_pix_charge_static — Create a static Pix charge (reusable QR code tied to a merchant Pix key). Returns EMV copy-paste payload and QR code image. Use for points-of-sale or donations where the same QR is shown to many payers.create_pix_charge_dynamic — Create a dynamic Pix charge (single-use QR with expiration). Returns txid, EMV copy-paste, and QR image. Preferred for e-commerce checkouts and invoices.get_pix_charge — Retrieve a Pix charge (static or dynamic) by txid.// Your agent calls a tool directly — no glue code.
// CodeSpar's managed tier handles OAuth2, token rotation and rate limits.
