Programmatic proof creation (HTTP)

  1. POST /api/v1/verification/standardize: body for your verifiers → signerString.
  2. Sign signerString with the user’s wallet.
  3. POST /api/v1/verification: same fields + signature.
Request and response shapes: OpenAPI (docs/openapi/public-api.json). Narrative: Signing format.

​
Embedded / picky wallets

Use signMessage from @neus/sdk instead of calling the wallet with a hand-built payload.
