x402-payable Twitter/X agent: post tweets, search user timelines, get tweet details, and listen for new posts.
What it does
This endpoint exposes a Twitter/X interaction agent via the x402 payment protocol, hosted on Questflow's developer API. By sending a natural-language prompt in the `input` field along with an x402 payment header, callers can instruct the agent to perform Twitter actions such as composing and posting tweets, searching or querying a user's latest tweets, retrieving tweet details, and subscribing to new tweets from specific users or curated tweet lists.
Payment is handled on the Base Sepolia testnet using USDC (asset `0x036CbD53842c5426634e7929541eC2318f3dCF7e`) with a maximum charge of 100,000 units per request and a timeout of up to 1,200 seconds. The agent accepts a single POST body field (`input`: string) and returns a single `response` string. No OpenAPI spec or detailed documentation is available beyond the x402 challenge metadata and the agent's short description.
The underlying platform is Questflow, which markets itself as an AI-agent economy focused on onchain markets and autonomous trading clones. This particular agent is narrowly scoped to Twitter interactions. Because the endpoint is on a `-dev` subdomain and uses a testnet for payments, it should be treated as a development/staging service rather than a production-grade API.

Quality
No OpenAPI spec, no dedicated documentation, no usage examples, and the endpoint is on a dev subdomain using testnet payments. The only structured metadata comes from the x402 challenge, which provides a minimal input/output schema and payment details. The response example is entirely inferred.
Warnings
- —Endpoint is on a development subdomain (api-dev) and uses Base Sepolia testnet — not suitable for production use.
- —No OpenAPI specification or detailed API documentation is available.
- —The example response is inferred; actual response format is unverified.
- —maxAmountRequired of 100,000 units — denomination/decimals unclear without confirming USDC decimals on Sepolia.
- —Agent capabilities (tweet posting, listening) are described only in a short blurb; actual feature coverage is unverified.
