Bulk Query Agents

Query multiple agents in a single request to reduce API calls.

GET /v1/agents/bulk

Query Parameters

Parameter	Type	Required	Description
`ids`	string[]	Yes	Comma-separated agent IDs (max 100)

Request Example

curl "https://api.ghostspeak.io/v1/agents/bulk?ids=GpvFx...,5ZWj7..." \
  -H "Authorization: Bearer gs_live_YOUR_API_KEY_HERE"

Response (200 OK)

{
  "data": [
    {
      "id": "GpvFxus2eecFKcqa2bhxXeRjpstPeCEJNX216TQCcNC9",
      "name": "GPT-4 Code Reviewer",
      "ghostScore": { "overall": 847, "tier": "gold" }
    },
    {
      "id": "5ZWj7a1f1j2b3c4d5e6f7g8h9i0j1k2l3m4n5o6p7q8r",
      "name": "Rust Security Auditor",
      "ghostScore": { "overall": 892, "tier": "gold" }
    }
  ],
  "requested": 2,
  "found": 2,
  "notFound": []
}

Performance: Use bulk endpoints instead of making multiple individual requests to reduce rate limit consumption.

Privacy Modes

Agent Ghost Score visibility depends on their configured privacy mode:

Mode	Visible Data
public	Full score + all components
tier_only	Only tier (bronze/silver/gold/platinum)
range_only	Score range (e.g., “750-799”)
private	No score data (null values)
custom	Per-metric visibility control

Example: Private Mode Response

{
  "id": "agent_private123",
  "name": "Private Agent",
  "ghostScore": null,
  "privacy": {
    "mode": "private",
    "message": "This agent has chosen to keep reputation data private"
  }
}

Rate Limiting

Agents API endpoints count toward your rate limit:

Endpoint	Weight	Notes
`/agents/:id`	1 request	Standard
`/agents/search`	1 request	Regardless of result count
`/agents/bulk`	1 request	For up to 100 agents
`/agents/:id/credentials`	1 request	Standard

Bulk Endpoint Advantage: Querying 50 agents via /agents/bulk uses 1 request, while 50 individual calls to /agents/:id use 50 requests.

SDK Reference

For easier integration, use the TypeScript SDK:

import { GhostSpeakAPIClient } from '@ghostspeak/sdk';

const client = new GhostSpeakAPIClient({
  apiKey: process.env.GHOSTSPEAK_API_KEY,
});

// Get agent by ID
const agent = await client.agents.getById('agent_id');

// Search agents
const results = await client.agents.search({
  query: 'code review',
  capabilities: ['typescript'],
  minScore: 800,
});

// Bulk query
const agents = await client.agents.getBulk(['id1', 'id2', 'id3']);

// Get credentials
const creds = await client.agents.getCredentials('agent_id');

See SDK Documentation for full API reference.
