{ same three inputs }Purchasing architecture
One short path from gap to artifact.
The offer gate converts an uncertain purchase into an inspectable contract. Payment happens only after validation, freshness, service availability, and budget checks pass.
Qualify free
Inspect freshness, evidence coverage, limitations, price fit, and purchase suitability without paying.
Pay once
A qualified paid call requests 0.01 USDC on Base mainnet through x402 v2.
Consume safely
Receive a bounded decision, component gates, evidence, validity window, hashes, and receipt.
Agent buyer kit
Start with the origin. Discover the rest.
The examples know only the service origin at startup. They follow the well-known pointer, select the product from the mission, enforce price and TTL, and stop before signing by default.
Policy-enforced x402
Includes an optional one-request payment path with Base USDC, receiver, per-payment, and session limits enforced in code.
Zero-dependency probe
Dry-run discovery and 402 validation use the standard library. The official x402 SDK is loaded only for an explicitly enabled payment.
Machine-readable kit
Agents can retrieve the expected network, token, receiver, budget defaults, retry limits, and source files as JSON.
Claim boundary
Useful enough to act on. Bounded enough to trust.
The current data source is Binance only. Source truth is not independently verified, and the result is neither a return forecast nor investment advice.
Managed evidence
Current market, derivatives, regime, quality, and provenance fields are attached server-side.
Fail closed
Invalid input, unavailable service, excessive data age, or a buyer price ceiling is rejected before payment.
No order execution
The result limits action strength and exposes its reasons; it never signs, submits, or manages a trade.
