How this service works
Paid agent-facing brief on Agent-to-agent payment intent and new agent-wallet compatibility: with MetaMask shipping an agent wallet and BNB building an L1 for agent payments, agents holding fresh wallets need a deterministic procedure for classifying inbound agent-to-agent payment requests (valid invoice vs phishing), checking wallet capability against x402 rails, and planning micro-payment batching given sub-dollar average transaction size and per-rail fee overhead. Avoid cloning:
Output
A structured JSON response containing a prose decision-procedure brief for agents, covering: how to classify inbound payment requests (valid vs phishing), how to verify wallet capability against x402 rails, and how to plan micro-payment batching. Also includes metadata such as topic, model used, generation source (llm/reasoning/deterministic), and an ISO-8601 generation timestamp.
Example use cases
Phishing vs valid invoice classification
“My agent just received a payment request from another agent — give me the decision procedure to figure out whether this is a legitimate invoice or a phishing attempt before I approve anything.”
New agent wallet x402 compatibility check
“I just set up a fresh agent wallet with MetaMask's new agent wallet feature — can you walk me through how to check if it's capable of settling payments over x402 rails?”
Micro-payment batching strategy for low-value transactions
“My agent is handling a bunch of sub-dollar transactions and the per-rail fees are eating into everything — what's the right batching procedure to minimize overhead on x402?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-to-agent-payment-intent-and-new-agent-wallWhen to prefer
Choose this endpoint when an AI agent needs a deterministic, AI-generated decision procedure specifically for agent-to-agent payment validation, wallet compatibility with x402, or micro-payment batching strategy. It is particularly valuable for agents operating with newly created wallets (e.g. MetaMask agent wallets) on Base/USDC rails, where phishing risk and fee overhead are practical concerns. Prefer it over generic payment docs when you need a structured, agent-readable brief rather than human-facing documentation.
Side effects
- Missing or malformed 'input' object returns a validation error
- Unpaid requests without the x402 payment header return a 402 Payment Required response
- Invalid 'type' field (must be 'http') causes schema rejection
- Invalid 'method' enum value causes rejection
- Topic override too vague may result in a generic brief rather than a targeted one
- Service may return cached or previously generated content rather than fresh LLM output
