Developer changelog

Verified changes across the Developer API, TypeScript SDK, MCP server, and hosted docs. Source candidates are labeled as such; npm remains the authority for published package versions.

Secure SDK quickstart and authentication guide

The hosted developer guide now takes a server-side Node.js app from API key setup to one completed video without exposing the bearer token to browser code.

  • Added an idempotent create-and-wait TypeScript example that follows server-provided polling hints.
  • Documented read-only key verification, same-key job ownership, and 401/403 recovery.
  • Added an explicit browser-to-server handoff and exposed-key revocation guidance.

SDK and MCP 0.1.2 source candidates

The repository source candidates expand agent workflows and harden package creation. The npm package pages remain authoritative for the latest published versions.

  • Expanded the SDK and standalone MCP server to the complete 18-tool agent surface.
  • Added cancellation, progress, idempotent retry, quota, readiness, and terminal retry-block metadata.
  • Added public-registry metadata and a build-on-pack guard so the MCP package cannot publish without its runnable output.

Rate-limit and error recovery contracts

The hosted guide now derives its status coverage from the public OpenAPI contract so new errors cannot silently leave retry documentation stale.

  • Documented every pacing header exposed by video create, status, and usage responses.
  • Separated retryable failures from terminal retry blocks and preserved safe Idempotency-Key reuse.
  • Added recovery guidance for every documented Developer API HTTP status.

Read-only playground and complete endpoint catalog

Developers can inspect the complete public beta surface and test read-only endpoints without storing an API key in browser storage.

  • Added the hosted endpoint inventory for voices, puppets, speech, uploads, usage, and video jobs.
  • Added a same-origin GET-only playground with explicit key clearing and stale-response protection.
  • Kept mutation and credit-spending endpoints outside the interactive playground.

Credit-backed developer video jobs

The Developer API added text- and audio-driven video creation with stable public job status, usage visibility, and idempotent submission recovery.

  • Added text and audio video-create endpoints plus same-key job polling.
  • Added usage, quota, reset-date, and key-level activity responses.
  • Added idempotency and explicit retry guidance to prevent accidental duplicate jobs.
