How this service works
Paid agent-facing brief on data-API billing mode selection for agents: when a data provider offers both classic API-key pay-per-use billing and x402/micropayment rails, which mode should an agent use for a given workload. Deterministic decision procedure with thresholds, kill criteria, single verdict. · Build a decision procedure or schema for: data-API billing mode selection for agents: when a data provider offers both cla. Blunt decision procedure, not marketing.
Output
A JSON object containing a plain-prose decision procedure (120+ words) advising agents on when to use paid-per-call billing for data APIs, along with metadata: the service slug, provider name, generation source (llm/reasoning/deterministic), model used, ISO-8601 timestamp, and a topic string. The 'brief' and 'procedure' fields contain the actionable guidance text.
Example use cases
Agent selects optimal data API billing
“My autonomous agent is about to call several paid data APIs and needs to know when per-call billing makes sense versus negotiating a subscription — can you get the decision procedure for data API billing mode selection so it can choose correctly?”
Building x402 data marketplace agent
“I'm building an agent that buys data from x402 merchants and I need a clear decision procedure it can follow for picking the right billing mode when a data provider offers a paid response — fetch that guide for me.”
Auditing agent payment strategy
“I want to review whether my agent's current approach to paying for data APIs is sound — pull the decision procedure for data API billing mode selection so I can check it against how my agent currently behaves.”

Endpoint
GEThttps://k2so.wrong.systems/api/services/data-api-billing-mode-selection-for-agents-when?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous agent needs structured, prose-form guidance specifically on data API billing mode selection in the x402 micropayment ecosystem. It is particularly useful when building or auditing agents that consume paid data APIs and need a codified decision procedure rather than ad-hoc logic. Prefer it over general LLM queries when you want a consistent, versioned, provider-signed decision brief that can be logged and audited.
Side effects
- HTTP 402 returned if USDC payment not settled before retry — agent must pay exact amount and include PAYMENT-SIGNATURE header
- Invalid method (e.g. POST) returns method-not-allowed error
- topic param ignored or misinterpreted if not a valid string
- Network timeout on k2so.wrong.systems infrastructure
- Payment signature mismatch causes re-issuance of 402
