How this service works
Batch version of the x402 evidence cross-check, for indexers and routers: up to 25 targets in one call. Each target returns the same field-level evidence, classification and confidence as the single-target resource. One failing target never invalidates the rest of the batch. Never pays any target and never signs an outgoing transaction.
Output
Returns per-target results for each of the submitted URLs, each containing the same field-level evidence, classification label, and confidence score as the single-target cross-check endpoint. A failing or non-responsive target does not affect other results in the batch.
Example use cases
Router pre-flight validation for x402 APIs
“Before I add these 18 x402 endpoints to my router's allow-list, can you run a batch cross-check on all of them and flag any that have mismatched metadata or low confidence scores?”
Indexer audit of newly discovered endpoints
“I just scraped 25 new x402 resources from Bazaar — can you batch cross-check them all and tell me their classifications and evidence quality so I know which ones to index?”
Revenue recovery compliance sweep
“I need an independent second opinion on these 15 monetized API endpoints — run a batch evidence cross-check and show me each one's field-level evidence and confidence without paying or signing anything.”
Technical details
Endpoint
GEThttps://agente.revenuerecoveryai.app/v1/x402/evidence-crosscheck-batch?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify more than one x402 resource at a time — it avoids N round-trips and per-call fees compared to calling the single-target cross-check repeatedly. Ideal for indexers building catalogs, routers validating allow-lists, or compliance sweeps over a portfolio of monetized endpoints. Prefer the single-target variant when you only need to check one URL.
Side effects
- Target URL unreachable or non-existent — that target returns an error entry; rest of batch proceeds
- More than 25 target_url parameters submitted — request may be rejected or truncated
- Non-HTTPS URL provided — may fail schema validation
- Method not in allowed enum (GET/HEAD/DELETE) — schema validation error
- Payment failure or insufficient USDC balance — entire call rejected before execution
