How this service works
Decision procedure for merchants converting an existing API-key or subscription-billed API to keyless x402 pay-per-call. Answers the conversion questions in order: which endpoints migrate first based on usage data and abuse risk, how to wire HTTP 402 PAYMENT-REQUIRED with payment-signature verification per request, how to rate-limit and set abuse thresholds when there is no user identity to key on, how to price per endpoint with floor and ceiling bounds, how to run shadow mode with dual billing
Output
A structured prose decision procedure (and optional metadata JSON) covering: endpoint prioritization by usage and abuse risk, HTTP 402 PAYMENT-REQUIRED wiring with per-request payment-signature verification, keyless rate-limiting and abuse threshold strategies, per-endpoint pricing with floor/ceiling bounds, and shadow-mode dual-billing setup. Response includes service slug, generation source, ISO-8601 timestamp, and model used.
Example use cases
Prioritizing endpoint migration order
“I have a REST API with about 20 endpoints currently behind API keys — which ones should I convert to x402 pay-per-call first based on usage risk and abuse exposure, and what criteria should I use?”
Setting per-call pricing with floor and ceiling
“I'm switching my API to keyless x402 per-call billing and I have no idea how to price each endpoint — can you give me a procedure for setting floor and ceiling price bounds for each one?”
Running shadow mode dual billing during cutover
“Before I fully cut over to x402, I want to run a shadow mode where both the old subscription billing and the new per-call billing happen simultaneously — what's the recommended procedure for doing that safely?”
Technical details
Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/keyless-x402-api-monetization-migrationWhen to prefer
Choose this endpoint when a merchant or API developer needs step-by-step procedural guidance for migrating an existing API-key or subscription-billed API to the x402 HTTP pay-per-call protocol. Prefer it over generic x402 documentation when you need decision-tree-style ordered answers covering endpoint selection, 402 wiring, keyless rate limiting, pricing bounds, and shadow mode rollout in a single call.
Side effects
- Missing or invalid 'type' or 'method' fields return a 400-level error
- No payment provided returns HTTP 402 PAYMENT-REQUIRED with payment details
- Unsupported HTTP method (e.g. POST, PUT) rejected by schema enum constraint
- Topic override field may yield off-topic or generic procedure if poorly specified
- LLM generation may occasionally produce incomplete or inconsistent guidance
