Add stablecoin issuance API surface by kphurley7 · Pull Request #578 · lightsparkdev/grid-api

kphurley7 · 2026-06-12T20:33:00Z

Important

Do not merge until the webdev implementation stack (lightsparkdev/webdev#28785 → #28734) has merged and the feature is ready to light up. Merging here publishes the endpoints: the nightly docs-sync workflow picks up openapi/ changes on main and the Stainless-documented spec feeds the public docs/SDKs. This PR stays draft until launch readiness.

Summary

Companion spec PR for the Brale stablecoin issuance stack in webdev (implementation: the flow-sliced stack starting at lightsparkdev/webdev#28785). Adds to the split OpenAPI source (openapi/):

12 paths under openapi/paths/stablecoins/: provider account links, stablecoin registration/list/get, external-account link sessions + linking (Plaid / direct bank entry / Grid external account), mint+burn quote create/get/execute, operations list/get.
48 schemas under openapi/components/schemas/stablecoins/: typed discriminated requests (quote operation types, mint funding sources, link methods), typed destination oneOf on quote/operation, payout-rail subset enum, list envelopes.
Stablecoin error codes added to Error400/Error404/Error409 enums (the generated clients hard-reject unknown codes, so these must ship before the backend returns them).
Stablecoins tag.

Bundle regenerated with make build; Redocly validation clean; spectral passes at --fail-severity=error.

Verification

The rebuilt bundle's stablecoin paths/schemas and error enums are deep-equal to the spec vendored in the webdev stack tip (verified programmatically). The only non-stablecoin delta vs that copy is ExchangeRateFees.total, which exists here and not yet in webdev's vendored copy (pre-existing drift; webdev picks it up on its next update_schema.sh sync).

🤖 Generated with Claude Code

Stablecoin issuance endpoints for the Grid API: provider account links, stablecoin registration, external accounts (Plaid link sessions, direct bank entry, Grid external accounts), mint/burn quotes and execution, and operations. Adds the stablecoin error codes to the Error400/404/409 enums and the Stablecoins tag. Spec source of truth for the webdev implementation stack starting at lightsparkdev/webdev#28029, which vendors this spec and generates the grid_api client from it.
