How this service works
Paid agent-facing brief on agent-facing single-purpose price query and micro-transaction decision procedure: how an agent should safely buy one small data point (one price, one quote, one fact) from an unfamiliar x402 endpoint without registering, including endpoint discovery, price honesty check, spend cap sizing, and receipt binding · Build a decision procedure or schema for: agent-facing single-purpose price query and mi-0. Blunt decision procedure, not marketing.
Output
A structured JSON response containing a 'brief' field with blunt prose decision procedure text, the topic slug, generation source (llm, reasoning, or deterministic), an ISO-8601 timestamp, and payment confirmation details including transaction hash and payer address.
Example use cases
Safe one-shot price data purchase
“My agent needs to buy a single crypto price from an x402 endpoint it has never used before — walk me through the exact checks it should do before paying, including how to verify the price is fair and what spend cap to set.”
Receipt binding for audit trail
“After my agent pays $0.002 USDC for a quote from an unknown x402 merchant, what's the correct procedure for binding the on-chain receipt to that specific data response so I have a verifiable audit trail?”
Endpoint discovery and trust evaluation
“My agent discovered a new x402 endpoint offering a one-time fact purchase — give me the decision procedure it should follow to evaluate whether the endpoint is trustworthy before committing any USDC.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-facing-single-purpose-price-query-and-micrWhen to prefer
Choose this endpoint when an AI agent needs a concrete, opinionated decision procedure for safely executing a one-time x402 micro-transaction — specifically around price honesty checks, spend cap sizing, and receipt binding. Prefer it over generic x402 documentation when you want a machine-readable, actionable brief rather than human-facing marketing copy, and when the agent is operating autonomously without prior registration with the data vendor.
Side effects
- Payment not attached or insufficient — endpoint returns HTTP 402 with payment requirements
- Invalid HTTP method (only GET/HEAD/DELETE accepted) — returns 400 or schema validation error
- LLM generation failure — result.ok may be false with no brief returned
- Stale or cached generation — generatedAt timestamp may indicate outdated content
- Network or endpoint unavailability — k2so.wrong.systems unreachable
