The console does not serve Call yet; this page describes the launch flow. {% endhint %} The discovery endpoints help you find Call listings by capability, kind, network, or category. Use them when you want the public directory without opening the vAPI console. The default result includes vAPI-verified listings and the fresh external mirror. Set `includeUnverified=true` to add self-listed rows with verification `none` or `requested`. Results are ordered by the Call groups `vapi`, `added`, `partner`, and `external`, then by relevance, trust, and freshness within a group. | Verification value | Meaning | | ------------------ | -------------------------------------------------- | | `none` | The listing is live but has not been reviewed. | | `requested` | Review was requested and the listing remains live. | | `verified` | The listing has the vAPI verification tier. | External mirrored rows are identified by `group: "external"`. Their `verification` value is `"none"`, so `external` is not a verification value. ## Search and discovery ### GET /api/call/discovery Search the cursor-paged discovery surface. Public clients can call it without authentication. **Auth:** none. | Query parameter | Description | | ------------------- | ----------------------------------------------------------------------------- | | `q` | Search query, up to 200 characters. | | `kinds` | Repeat this parameter to filter by `api`, `service_offer`, or `open_request`. | | `network` | Network filter. | | `cursor` | Opaque cursor for the next page. | | `limit` | Page size from `1` to `50`. | | `includeUnverified` | Add unverified self-listed rows when `true`. | ```bash curl 'https://api.vapinetwork.ai/api/call/discovery?q=weather&kinds=api&includeUnverified=true&limit=2' ``` Repeat the parameter to request several kinds, for example `kinds=api&kinds=service_offer`. The bracketed parameter `kinds[]` returns `400`. The response envelope contains `protocol`, `items`, `nextCursor`, `unavailableKinds`, and `rankingVersion`. Pass `nextCursor` as `cursor` until it is `null`, and inspect `unavailableKinds` for partial availability. This captured response is shortened to one item. ```json { "protocol": "vapi.marketplace.discovery/1", "items": [ { "ref": "https://weather.cyberwarex.com/forecast", "card": { "title": "weather.cyberwarex.com/forecast", "summary": "Weather forecast for a location (global, keyless): current conditions, an hourly series (up to 48h) and a daily summary (up to 10 days: min/max temp + condition), from met.no.

Its body, status codes, and authentication match the canonical route. **Auth:** none. | Query parameter | Description | | ------------------- | ----------------------------------------------------------------------------- | | `q` | Search query, up to 200 characters. | | `kinds` | Repeat this parameter to filter by `api`, `service_offer`, or `open_request`. | | `network` | Network filter. | | `cursor` | Opaque cursor for the next page. | | `limit` | Page size from `1` to `50`. | | `includeUnverified` | Add unverified self-listed rows when `true`. | ```bash curl 'https://api.vapinetwork.ai/api/marketplace/discovery?q=weather&limit=2' ``` Repeat the parameter to request several kinds, for example `kinds=api&kinds=service_offer`. The deprecated path adds a successor header and returns the same envelope as the canonical path.

The public contract does not specify a fuller response wrapper here. Checked on 2026-10-02. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.vapinetwork.ai/reference/http-api/discovery-and-services.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
