How this service works
Decision procedure for an agent platform or autonomous agent choosing who operates payment infrastructure: a managed facilitator, a self-hosted ERC-8004/x402 server, or direct protocol integration. Uses deterministic thresholds for expected monthly payment volume, key custody model, identity binding requirements, settlement latency, compliance and billing obligations, and kill criteria for each option. Ends with a build, rent, or integrate verdict.
Output
A JSON object containing a plain-prose decision procedure brief (120+ words) tailored to payment plumbing operator selection, including the model that generated it, the topic, a timestamp, and whether the result came from an LLM, reasoning engine, or deterministic logic. The 'brief' and 'procedure' fields carry the actionable guidance text an agent can parse and act on.
Example use cases
Bootstrapping a new x402 agent merchant
“I'm building a new autonomous agent merchant on Base and need a concrete decision procedure for picking which payment plumbing operator to use — walk me through the criteria and selection logic.”
Comparing payment infrastructure options mid-build
“My agent is mid-development and I'm unsure whether to switch payment plumbing operators — can you give me the decision procedure for evaluating payment plumbing operator choices in an x402 context?”
Agent self-governance for payment routing
“My autonomous agent needs to decide at runtime which payment plumbing operator to route through — give me the decision brief so it can make that call programmatically without human input.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/payment-plumbing-operator-selector?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous agent or developer needs structured, LLM-generated decision guidance specifically for selecting a payment plumbing operator within an x402 ecosystem on Base. Prefer it over generic documentation when you need machine-readable prose a downstream agent can act on, especially in agentic pipelines that must self-govern infrastructure choices without human intervention.
Side effects
- HTTP 402 returned before payment — agent must settle exact USDC amount and retry with PAYMENT-SIGNATURE header
- Payment signature invalid or expired — results in rejected retry
- Incorrect HTTP method used (only GET/HEAD/DELETE accepted) — schema validation error
- Topic override too vague — LLM may return generic procedure not tailored to specific context
- Service temporarily unavailable — upstream agent heartbeat missed
