Bold

v0.1.0API Key

Colombian acquirer with a clean REST charge API: your agent creates a payment intent and takes cards or PSE bank debit in one call.

7 tools2 env vars🇨🇴 Colombiastable on npm

What your agent can do

Bold gives your agent 7 tools it calls directly — pick the ones it needs, in Claude, Cursor, or any MCP client.

  • create_payment_link — Create a Bold payment link (POST /online/link/v1). Returns payload.payment_link (LNK_ id) and payload.url to hand to the payer. Supports cards, PSE, Nequi and Botón Bancolombia; restrict with payment_methods.
  • create_pse_payment_link — Convenience wrapper: create a Bold payment link restricted to PSE bank debit (payment_methods=["PSE"]).
  • create_card_payment_link — Convenience wrapper: create a Bold payment link restricted to cards (payment_methods=["CREDIT_CARD"]).
Example call
// Your agent calls a tool directly — no glue code.
// CodeSpar's managed tier handles OAuth2, token rotation and rate limits.
const result = await session.call("create_payment_link", { /* ... */ });
