Every day, AI agents make decisions on our behalf — buying, sending emails, signing documents — and nobody verifies there's a real human behind them.
Soulprint solves this with Zero-Knowledge Proofs: 100% on-device, open source (MIT), free to run. soulprint.digital
🇨🇷 Costa Rica's Cédula de Identidad is not in Soulprint yet. You can add it in ~30 minutes with one PR.
What Soulprint does
npx soulprint verify-me # scan ID + face match — all local
# → SPT token (score 0-100)
# AI agent includes token in every call
# X-Soulprint: eyJ... (score: 84)
# API verifies in 3 lines:
import { requireSoulprint } from "soulprint-mcp";
server.tool("premium", requireSoulprint({ minScore: 80 }), handler);
ZK proof: Circom 2.1.8 · Groth16 · 844 constraints · 564ms prove · 25ms verify.
🇨🇷 Costa Rica: Cédula de Identidad
Cédula: 9 dígitos (1-XXXX-XXXX).

const CR: CountryVerifier = {
countryCode: "CR",

const doc_number = ocrText.match(/(\d{9})/)?.[1] ?? "";

},
validate(docNumber: string): NumberValidation {
// exactly 9 digits
return { valid: /^\d{9}$/.test(docNumber) };
},
};
export default CR;
Then add one line in registry.ts:
import CR from "./countries/CR";
// add to registry map: "CR": CR,
