Data-Acquisition Endpoint Pre-Payment Contract Check
x402
Data-Acquisition Endpoint Pre-Payment Contract Check is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-19).
Returns a paid, LLM-generated decision procedure for evaluating agent-facing data-acquisition endpoints: honest schema verification, smoke-test contract validation, and price honesty checks to differentiate legitimate endpoints from weak 404 merchants.

How this service works
Paid agent-facing brief on agent-facing data-acquisition procedure with honest schema, smoke-verified contract, and price honesty, differentiated from weak 404 merchants · Build a decision procedure or schema for: agent-facing data-acquisition procedure with honest schema, smoke-verified contract, and price honesty, differentiated from weak 404 merchants. Include inputs, thresholds, failure modes. Falsifier: If free docs al-0. Blunt decision procedure, not marketing.
Output
A JSON object containing a plain-prose decision procedure (120+ words) for agent-side evaluation of data-acquisition endpoints, including schema honesty checks, smoke-test contract verification steps, price honesty thresholds, and failure mode descriptions. Also returns the generation model, topic, service slug, ISO-8601 timestamp, and generation source (llm, reasoning, or deterministic). The 'paid' flag confirms successful x402 payment processing.
Example use cases
Pre-payment API legitimacy check
“Before my agent pays for this data feed, give me a blunt decision procedure to verify the endpoint has an honest schema, real pricing, and passes a basic smoke test — I don't want to waste funds on a 404 merchant.”
Building agent due-diligence workflow
“I'm building an autonomous agent that discovers and pays for data APIs over x402 — can you generate a structured procedure with inputs, thresholds, and failure modes it should run to validate any data-acquisition endpoint before making the first payment?”
Differentiating trustworthy x402 data providers
“I keep hitting endpoints that return 404s or have misleading pricing — give me a procedure my agent can follow to distinguish legitimate x402 data providers with verified contracts from weak or dishonest merchants.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-facing-data-acquisition-procedure-with-hon?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs a structured, blunt decision procedure for evaluating the trustworthiness of agent-facing data-acquisition endpoints — specifically when verifying schema honesty, smoke-testing contracts, and assessing price legitimacy in x402 ecosystems. Prefer it over generic API validation tools when the context is x402-native agent payments and the concern is distinguishing legitimate data merchants from weak 404 providers. Best suited for autonomous agents running pre-payment due diligence workflows.
Side effects
- Endpoint returns 402 if payment is not attached — agent must attach x402 payment header
- If meta=1 is set, returns free metadata JSON without payment and without the full decision procedure
- LLM generation failure may result in ok:false with no brief returned
- Invalid or unsupported HTTP method returns an error (only GET, HEAD, DELETE allowed)
- Network or provider outage at k2so.wrong.systems results in connection failure with no fallback
- Topic override not recognized may produce a generic rather than topic-specific procedure
