How this service works
Evaluate a non-personal capability taxonomy identifier and return a synthetic match signal
Output
Returns a synthetic match signal indicating the degree or nature of alignment between the submitted capability taxonomy identifier and known taxonomy entries; likely includes a match score or boolean signal along with relevant metadata about the resolved identifier.
Example use cases
Capability ID taxonomy lookup
“I have a capability taxonomy identifier 'TX-0091' and I need to know what synthetic match signal the zero-signal phase0 resolver returns for it — can you run that evaluation?”
Agent capability alignment check
“Check whether taxonomy identifier 'CAP-INFRA-7' aligns with anything in the zero-signal phase0 system and return whatever match signal it produces.”
Automated taxonomy batch pre-filter
“Before I route these capability codes to the next stage, can you resolve identifier 'PHASE-X402-33' through the zero-signal resolver to see what match signal it returns?”

Endpoint
POSThttps://zero-signal-phase0.polar-tern.workers.dev/v1/resolve/x402When to prefer
Use this endpoint when you need to evaluate a specific non-personal capability taxonomy identifier against a synthetic match signal framework, particularly in workflows involving x402-protocol-gated capability discovery or classification pipelines built around the polar-tern worker infrastructure.
Side effects
- Invalid or unrecognized taxonomy identifier returns no match or error signal
- Malformed POST body causes 400 bad request
- Payment failure via x402 protocol prevents resolution
- Identifier outside supported taxonomy namespace returns null or zero signal
- Rate limiting or worker timeout on the Cloudflare edge returns 5xx
