Topic hashtag research API

What to build with it

Collect content for a specific intent.
Read the agent's hashtag aggregates and keep the result window.
Validate candidate hashtags against the actual posts before using them in a content plan.

Provider reference: Virlo documentation. Authentication uses a provider-issued Bearer token, stored on your server.

Endpoints and inputs

1 documented operation. Query and path fields are listed separately from JSON request-body fields.

GET/v1/agents/{id}/hashtags

Path and query parameters

id: string (path) · required
limit: number (query) · optional · default: 50 · minimum: 1 · maximum: 100
page: number (query) · optional · default: 1 · minimum: 1
sort: string (query) · optional · values: volume, growth, avg_views · default: "volume"

Documented response fields

data: array · required
data[].hashtag: string · required
data[].video_count: number · required
data[].total_views: number · required
data[].avg_views: number · required

pagination.page: number · required
pagination.limit: number · required
pagination.total: number · required
pagination.total_pages: number · required

Documented HTTP responses: 200, 401, 404, 429. Handle each non-success response explicitly; do not silently convert a failed lookup to an empty result.

Before you integrate

The result describes the agent's collection, not all posts carrying the hashtag across the platform.

Check the provider's current price, allowed use and retention terms before sending requests. An optional field can be absent; the schema alone does not establish its completeness or accuracy.

Give this task to your coding agent

topic-hashtag-api agent prompt

Help me implement topic hashtag research api using the documented Virlo API.

Reference: https://allthemapis.com/social-media-apis/topic-hashtag-api
Provider documentation: https://dev.virlo.ai/docs/agents
Base URL: https://api.virlo.ai
Starting operation: GET /v1/agents/{id}/hashtags

Read the current provider docs and confirm the required inputs before writing code. Load VIRLO_API_KEY from a server-side environment variable and use Bearer authentication. Do not put the key in client code, logs, analytics, or the chat.

Ask me for any missing video URL, creator handle, research intent, or job ID. Do not invent a result. Ask for approval before starting billable lookups, recurring jobs, or destructive changes. For jobs, keep the returned ID and poll with the documented delay instead of starting the job twice. Handle pagination, rate limits, partial results, and missing fields explicitly.

Build the smallest integration for this task:
1. Collect content for a specific intent.
2. Read the agent's hashtag aggregates and keep the result window.
3. Validate candidate hashtags against the actual posts before using them in a content plan.

Return the code, the environment variables I need, and a short explanation of what was actually retrieved versus inferred. Do not execute paid requests until I approve.
