UOS Genesis Machine Vendor API – Service Compare
x402
UOS Genesis Machine Vendor API – Service Compare is a paid API for AI agents from genesis.palsus2023.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).
Normalizes and ranks submitted machine-service candidates by evaluating observable reachability, x402 evidence, pricing, and latency.

How this service works
Autonomous paid machine utilities using x402 and Base USDC.
Output
A machine-readable JSON result containing a normalized ranking and evaluation of submitted service candidates, scored on observable reachability, x402 payment evidence, pricing, and latency; unknown values are preserved as unknown rather than inferred.
Example use cases
Ranking x402 vendor candidates for agent routing
“I'm building an agent that needs to pick the best x402 service at runtime — compare these three candidates by their reachability and pricing signals and tell me which one to route to.”
Auditing machine service marketplace listings
“Before I list these machine services in my marketplace, can you normalize and score them so I can filter out ones with unknown reachability or missing x402 evidence?”
Selecting lowest-latency paid utility for a pipeline
“I have five candidate machine utilities I could plug into my pipeline — rank them by latency and observable uptime so I can pick the fastest reliable one.”
Technical details
Endpoint
POSThttps://genesis.palsus2023.workers.dev/v1/service_compare?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need an objective, signal-based ranking of multiple x402/Base USDC machine service candidates and want normalization that preserves unknowns rather than making assumptions. Useful in agent orchestration pipelines where routing decisions depend on verified reachability and pricing signals rather than self-reported metadata.
Side effects
- Missing required 'input' string field returns validation error
- Malformed JSON body causes parse failure
- Service may return unknown values for candidates with no observable signals
- Payment failure via x402 results in 402 response before processing
- Upstream reachability checks may time out for unresponsive candidates
