Example use cases
Cloudflare Wallets aggregation routing decision
“When my agent hits a 402 challenge that lists Cloudflare Wallets-style aggregated facilitators including Coinbase and Stripe, what's the decision procedure for picking which one to actually use? Give me the blunt criteria, not a sales pitch.”
New agent payment stack provider selection
“I'm building an autonomous agent that needs to pay x402 merchants and I need to decide which wallet facilitator to back — can you give me a decision procedure comparing Coinbase, Google, Visa, and Stripe as the underlying provider?”
Per-call facilitator arbitration schema
“Give me a schema or decision tree my agent can run each time it sees a 402 response with multiple wallet facilitator options, so it can automatically pick the best one based on cost, reliability, and trust — for providers like Coinbase, Google, and Stripe.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/multi-facilitator-x402-wallet-selection-for-agenWhen to prefer
Choose this endpoint when an AI agent needs a neutral, engineering-focused decision procedure for x402 multi-facilitator scenarios and you want an LLM-generated brief rather than writing the logic yourself. Particularly useful when integrating Cloudflare Wallets-style aggregation layers where multiple facilitators (Coinbase, Google, Visa, Stripe) may appear in a single 402 challenge. Prefer this over generic payment documentation when you need agent-executable criteria, not marketing material.
Side effects
- Payment not included — returns 402 challenge requiring $0.002 USDC via x402 before content is delivered
- Invalid method (POST, PUT, PATCH) — only GET/HEAD/DELETE accepted
- Malformed input schema — missing required 'type' or 'method' fields returns validation error
- Topic override param ignored if not a string — falls back to default procedure topic
- Service temporarily unavailable — upstream LLM/reasoning provider may time out on complex procedure generation
