Deep async knowledge search via SSE stream — AI research agent with full pipeline on Tako
What it does
Tako's `/api/mpp/v1/threads/deep` endpoint performs deep knowledge search using an AI research agent and returns results as a Server-Sent Events (SSE) stream. It is part of Tako's broader data visualization and research platform, which searches structured datasets, generates charts, and builds research reports grounded in licensed and real-time data sources.
This endpoint accepts a JSON POST body with a natural-language query and streams back a full research pipeline response. Payment is handled via the MPP protocol using the Tempo method (pathUSD on chain 4217) at a fixed price of approximately $0.55 per request. No signup or API key is required — callers authenticate through the 402 payment flow. The provider covers gas fees (feePayer: true).
Tako also exposes related endpoints for fast search (~$0.037/call), data visualization (~$0.037/call), chart editing (~$0.007/call), full report generation (~$5.50/call, async with polling), and a ThinViz card creator (~$0.004/call). All endpoints are documented in the OpenAPI spec and accept JSON POST bodies. Documentation is available at docs.tako.com.
Capabilities
Use cases
- —Conducting in-depth, evidence-backed research on companies, markets, or macro trends via natural language queries
- —Streaming real-time research pipeline results into an AI agent or application
- —Embedding deep research capabilities into products without maintaining search indexes
- —Generating sourced, structured insights for investment analysis or competitive intelligence
- —Powering LLM agents with grounded, citable data answers
Fit
Best for
- —AI agents needing deep, sourced research results streamed in real time
- —Developers embedding research capabilities into apps without API keys
- —Research and strategy teams automating evidence-backed analysis
- —Investment analysts seeking structured company and market data
Not for
- —Simple keyword-based web search (use a traditional search engine)
- —Free or high-volume bulk data scraping (each call costs ~$0.55)
- —Use cases requiring sub-second latency (deep search involves a full research pipeline)
Quick start
curl -X POST https://tako.com/api/mpp/v1/threads/deep \
-H "Content-Type: application/json" \
-H "Authorization: <MPP-payment-token>" \
-d '{"query": "How are AI productivity startups performing in 2025?"}'Example
Request
{
"query": "Compare OpenAI and Anthropic in web traffic and engagement"
}Endpoint
Quality
The endpoint is live (402 MPP challenge captured) with a valid OpenAPI spec listing multiple endpoints, pricing, and descriptions. However, the request/response schemas are untyped (generic `object`), no example responses are provided, and detailed documentation (docs.tako.com) was not crawled. The SSE stream format is undocumented in the available material.
Warnings
- —Request body schema is untyped (generic object) — exact fields for the query payload are not documented in the OpenAPI spec
- —Response schema and SSE event format are not documented in the crawled material
- —Full developer documentation at docs.tako.com was not included in the crawl bundle
- —The currency token address 0x20c000000000000000000000b9537d11c60e8b50 is assumed to be pathUSD (6 decimals) based on the Tempo method and chain 4217; if decimals differ, the price would change
- —robots.txt disallows GPTBot, ClaudeBot, and other AI crawlers
