Pay-per-use X/Twitter search agent returning real-time tweets, threads, and sentiment via x402 micropayments.
What it does
The 402box X/Twitter Search Agent (x_searcher) is an AI-powered endpoint that performs advanced searches on X/Twitter to find tweets, threads, and conversations based on a user-supplied query. It is part of the 402box Agentic Suite, a collection of pay-per-use AI agents settled via the x402 micropayment protocol using USDC on the Base network.
According to the provider's landing page, each call costs $0.05 in USDC. The agent is designed for use cases such as market research, brand monitoring, trend analysis, and competitive intelligence. It returns real-time insights from social media discussions, trending topics, and user sentiment.
Important caveats: during probing, the endpoint did not return the expected HTTP 402 challenge on either GET or POST, and no OpenAPI schema, documentation page, or API reference was found. The root origin page is reachable and describes the agent, but the actual /x_searcher path could not be confirmed as live. There is no published request/response schema, so the exact input format and output structure are unknown. Users should verify endpoint availability before integrating.
Capabilities
Use cases
- —Market research by querying real-time X/Twitter discussions on specific topics or products
- —Brand monitoring to track mentions, sentiment, and conversations about a company or product
- —Trend analysis to identify emerging topics and viral content on X/Twitter
- —Competitive intelligence by searching for competitor mentions and public sentiment
- —Gathering social proof or community reactions around events or announcements
Fit
Best for
- —AI agents that need programmatic access to X/Twitter search results without managing API keys
- —Developers wanting pay-per-call social media search without monthly subscriptions
- —Automated pipelines that combine social media signals with other data sources
Not for
- —High-volume bulk scraping of X/Twitter data (pay-per-call pricing adds up quickly)
- —Applications requiring guaranteed SLA or uptime (endpoint liveness could not be confirmed during probing)
- —Use cases needing historical Twitter archive access beyond what real-time search provides
Quick start
# No confirmed live 402 challenge was captured, so the exact call
# pattern is uncertain. Based on x402 convention, expect something like:
curl -X POST https://agents.402box.io/x_searcher \
-H "Content-Type: application/json" \
-d '{"query": "bitcoin sentiment today"}'Example
Request
{
"query": "bitcoin sentiment today"
}Endpoint
Quality
The endpoint did not return a 402 challenge on GET or POST, so liveness could not be confirmed. No OpenAPI schema, no documentation, and no response examples are available. The only source of information is the provider's landing page, which gives a brief description and price. This is effectively a stub listing.
Warnings
- —Endpoint did not return HTTP 402 on GET or POST — liveness unconfirmed
- —No OpenAPI or JSON schema available; request/response format is unknown
- —No /docs, /api, or /README pages found on the origin server
- —Request and response examples are inferred, not sourced from documentation
