Connectors block 11: Gamma, ElevenLabs, HeyGen, Replicate, Mistral, xAI, Telnyx, Eventbrite, Whop, Botpress

[helpcodeai]

Block 11: ten connectors that users searched for in the catalog without finding one. All ten are listed, which brings the catalog to 422 adapters and 6,204 tools.

Connector	Tools	Notes
Gamma	11	API v1.0 (v0.2 was switched off in January). Generate presentations, documents and webpages, from text or from a template, then poll for the result and exports. API keys need a paid Gamma plan.
ElevenLabs	22	Voices, text to speech, transcription, dubbing, history and conversational agents. The engine has no binary responses, so speech uses ElevenLabs' asynchronous endpoint, which returns an MP3 link valid for about an hour. Sound effects are left out because they only return raw audio and are not kept in history.
HeyGen	19	Built on API v3, because v1 and v2 (including /v2/video/generate) are retired on 31 Oct 2026. Avatar videos, templates, video translation, video agent, photo avatars.
Replicate	17	Search models, read input schemas, run official models, versions and deployments with Prefer: wait, predictions. Output links expire after an hour.
Mistral	23	Chat, FIM, embeddings, moderation, classification, OCR, Agents and Conversations (beta, also the only route to web search), files and batch jobs. Fine-tuning is left out: Mistral removed it from the spec and both SDKs.
xAI Grok	14	Responses API (xAI labels chat completions legacy), web and X search as server-side tools (Live Search parameters are gone), deferred completions, image generation and editing.
Telnyx	26	Balance, numbers, SMS/MMS, call control (dial, speak, hang up), detail records, usage reports, recordings, lookup, Verify, AI assistants. Ordering numbers is installed off.
Eventbrite	24	Organizations, events (create, update, publish), description, ticket classes, attendees, orders, venues, discounts, sales report. Cancel and delete are installed off. Public event search no longer exists in the API, and the instructions say so.
Whop	20	API v1 with an account key: products, plans, memberships, licence key check, members, payments, promo codes, experiences, forum posts, webhooks. Cancel and refund are installed off.
Botpress	21	Admin, Runtime, Tables and Files APIs: bots, logs, analytics, issues, conversations, messages, users, events, table rows, files. Deleting rows is installed off.

Safety. Every call that spends credits or money (generation, SMS, calls, dubbing, image models) states the cost and asks the model to confirm with the user first. Deletes, cancellations and refunds are installed switched off. Secrets in responses (webhook secrets, messaging profile secrets, barcodes, client secrets) are excluded.

Verification. No Cloud workspace has a hand-built connector for these services, so there were no customer keys to try. Every tool was diffed against the vendor's official OpenAPI spec and official SDK or integration code (path, method, auth header, query and body names, response fields used in the mappings), and the mismatches were fixed. Every route was then called with a fake key: all answer 401 (xAI answers 400, ElevenLabs 400 for a malformed key), while made-up routes answer 404. Replicate and Botpress check the token before routing, so for them the probe only proves the prefixes and the paths rest on the spec diff. Live specs cover reads behind RUN_<SLUG>_LIVE=1 and paid calls behind a second flag; none has run with a real account yet.

Official MCP servers. Gamma, HeyGen and Whop have hosted MCP servers, but they use OAuth with the web plan or full admin scope; Telnyx's exposes generic endpoint invocation. The REST adapters keep the tool set curated.

Logos. Vendor files where they exist. Telnyx only publishes its square mark as PNG, so the wordmark is used. Whop has no SVG, so its official PNG is wrapped in an SVG like 28 existing logos.
