Pay-per-call Twitter agent: post tweets, search timelines, and monitor accounts via x402 on Base.
What it does
This Questflow-hosted Twitter agent exposes common Twitter/X operations—posting tweets, searching a user's latest tweets, retrieving tweet details, and listening for new posts from specific accounts or tweet lists—through a single x402-payable HTTP POST endpoint. The agent accepts a natural-language prompt in the `input` field and returns a text `response`.
Payment is handled via the x402 protocol on the Base network using USDC (contract 0x8335…2913). The maximum amount required per call is 100,000 units (likely 0.10 USDC given 6-decimal USDC), with a maximum timeout of 1,200 seconds. The endpoint is discoverable and returns `application/json`.
Documentation is minimal: there is no OpenAPI spec, no dedicated docs page, and no public pricing page beyond what the x402 challenge header reveals. The agent is part of Questflow's broader AI-agent platform, which focuses on autonomous onchain trading clones, but this particular agent is scoped to Twitter interactions only. Because the endpoint schema is simple (one string in, one string out) and no further documentation exists, callers should experiment with prompt phrasing to discover the full range of supported Twitter actions.
Capabilities
Use cases
- —Posting tweets programmatically from an AI agent workflow
- —Monitoring a Twitter account for new posts and triggering downstream actions
- —Searching a user's recent tweets for sentiment analysis or content aggregation
- —Retrieving full tweet details (text, metadata) by tweet reference
- —Listening to curated tweet lists for real-time social signals
Fit
Best for
- —AI agents that need to read or write tweets without managing Twitter API keys directly
- —Developers wanting pay-per-use Twitter access via crypto micropayments
- —Automated social-media monitoring pipelines on Base/L2
Not for
- —High-volume bulk Twitter data collection (rate limits and per-call cost may be prohibitive)
- —Use cases requiring fine-grained Twitter API v2 parameters (endpoint only accepts free-text prompts)
- —Users who need deterministic, structured Twitter API responses (output is a single string)

}Endpoint
Quality
The x402 challenge provides a basic input/output schema and payment details, but there is no OpenAPI spec, no docs page, no usage examples, and no detailed capability documentation. The response example is entirely inferred. Effectively a stub listing.
Warnings
- —No OpenAPI or dedicated API documentation available
- —Output schema is a single unstructured string; no structured tweet objects
- —Example response is fabricated/inferred—actual format unknown
- —No rate-limit or quota information disclosed
- —maxAmountRequired of 100000 units—actual USDC cost unclear (likely 0.10 USDC with 6 decimals, but unconfirmed)
- —Platform primarily markets AI trading clones; this Twitter agent's maintenance status is unclear
