How this service works
OPX builds machine-facing infrastructure and paid tools for x402 commerce. Its current live tool helps agents choose between tested x402 web-search providers before spending using recent paid performance evidence.
Output
Returns a JSON object with the recommended primary provider (name, upstream, confidence score), a ranked list of fallback providers, a decision ID for traceability, a feedback token and outcome URL for reporting results, and the echoed request parameters (intent, freshness, budget).
Example use cases
News search provider selection
“I need to run a news search and want to know which x402 provider OPX recommends right now — it needs to return results from the last week and cost less than $0.02.”
Research task with latency constraint
“Can you ask OPX which search provider to use for a research-style query? I want the best option under 800ms p50 latency and I'm okay spending up to $0.05.”
Company lookup with fallback planning
“I need to do a company search via x402 — can you get OPX's current recommendation including fallback options in case the primary provider is down?”
Technical details
Endpoint
GEThttps://opx-status.dev/api/route?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to dynamically select the best-performing x402 web search provider at call time rather than hardcoding a specific provider. It is especially valuable when you want to factor in real-world probe latency, budget caps, freshness requirements, and intent type simultaneously, and when you want built-in fallback options if the primary recommendation fails.
Side effects
- Missing required 'task' query parameter returns a validation error
- Unsupported intent or freshness enum value causes a 400 bad request
- No provider available within budget or latency constraints may return empty or low-confidence recommendations
- Stale probe data may reduce confidence score and reliability of recommendation
- Payment failure or x402 auth issue blocks access entirely
