Pay-per-call AI agent swarm on Questflow, accessible via x402 micropayments on Base.
What it does
"new Aster" is an AI agent swarm endpoint hosted on Questflow's x402-compatible API. It accepts a text message via HTTP POST and returns a text response from the agent. Payment is handled inline using the x402 protocol on the Base network, settling in USDC (asset 0x8335…2913) with a maximum cost of 500,000 units (likely 0.50 USDC given 6-decimal USDC) per request.
Questflow is a platform that lets users create autonomous AI "Clones" that aggregate onchain markets such as Polymarket, Pump.fun, OKX, and Opinion Labs. These agents scan markets, detect patterns, and can execute trades or sell signals. The "new Aster" swarm appears to be one such agent exposed as a pay-per-use endpoint. The input schema is minimal: a single required string field called "input" containing your message, and the output is a single string field called "response."
Documentation for this specific swarm is extremely sparse. There is no OpenAPI spec, no dedicated docs page, and no detailed description of what "new Aster" specifically does beyond being a Questflow-powered agent. The x402 challenge provides the payment terms and basic I/O schema, but the agent's capabilities, knowledge domain, and behavior are not documented. The maximum request timeout is 1200 seconds (20 minutes), suggesting potentially long-running agent tasks.
Capabilities
Use cases
- —Querying an autonomous AI agent for market insights or analysis via a single API call
- —Integrating a pay-per-use AI agent into automated workflows using x402 micropayments
- —Programmatic access to a Questflow swarm agent from other AI agents or applications
Fit
Best for
- —Developers building agent-to-agent payment flows on Base
- —Users wanting pay-per-call access to a Questflow AI agent without a subscription
- —Experimenting with x402 protocol-based AI service consumption
Not for
- —Users needing well-documented, production-grade APIs with full OpenAPI specs
- —Applications requiring deterministic, structured outputs with guaranteed schemas
- —Free or low-cost general-purpose LLM chat (each call costs USDC)

Quality
The listing is essentially a stub. The only concrete technical information comes from the x402 challenge header, which provides payment terms and a minimal I/O schema. There is no OpenAPI spec, no dedicated documentation, no examples, and no description of what 'new Aster' specifically does. The agent's domain, capabilities, and behavior are entirely unknown.
Warnings
- —No OpenAPI spec or dedicated API documentation available
- —Agent behavior and domain expertise are completely undocumented
- —The name 'new Aster' and description provide no meaningful information about the agent's purpose
- —Example response is entirely fabricated/inferred — actual output format and content are unknown
- —Maximum cost of 500000 units in USDC — exact dollar amount depends on decimal interpretation
- —1200-second timeout suggests potentially very long response times
