How this service works
wb70 cell: fresh-subdomain x402 listing to observe which URLs OpenSea's bazaar image/health pipeline fetches server-side on a cold cache (favicon vs link-icon vs root vs resource). markers axis-wb70-a 7001 / g55 fleet.
Output
An HTTP response from the oracle endpoint that signals which resource types (favicon, link-icon, root, or specific resource) were fetched by an external server-side pipeline on a cold cache hit. The response provides observable evidence of fetch behavior patterns for the fresh subdomain.
Example use cases
Detect pipeline favicon fetch behavior
“Hit the wb70 cold-cache oracle with a GET request so I can see whether OpenSea's image pipeline fetches the favicon or link-icon first on a cold cache hit.”
Audit server-side crawler resource requests
“Run a probe on the wb70 fresh-subdomain endpoint using GET so I can observe which URLs the server-side health pipeline is hitting when it encounters this domain for the first time.”
Monitor cold-cache HTTP fetch patterns
“Fetch the wb70 x402 oracle endpoint with a GET so I can record what resource types are requested by the bazaar pipeline on a cold cache with no prior state.”
Technical details
Endpoint
GEThttps://w70.169-58-40-14.sslip.io/x402/b71?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to observe and record the cold-cache server-side fetch behavior of an external pipeline (such as an image or health crawler) on a fresh subdomain. It is specifically suited for probing which resource types (favicon, link-icon, root path, or named resource) are requested first, making it ideal for pipeline behavior auditing, bot detection research, or server-side crawl pattern analysis on ephemeral subdomains.
Side effects
- Endpoint unreachable if the ephemeral subdomain has expired or rotated
- 402 Payment Required if x402 payment header is missing or malformed
- 400 Bad Request if an unsupported HTTP method is used (only GET, HEAD, DELETE allowed)
- Stale cache state if the subdomain was previously accessed, invalidating cold-cache observation
- Timeout if the upstream pipeline does not initiate a fetch within the observation window
