Stride20k Endpoint Scorecard
x402
Stride20k Endpoint Scorecard is a paid API for AI agents from gateway.stride20k.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).
Returns a due-diligence scorecard for a single x402 resource URL, showing its first observation date, catalog listing consistency, observation history, and current listing status in public catalogs like CDP Bazaar and Agentic.Market.

How this service works
Due-diligence scorecard for a single x402 resource before an agent pays it: when we first observed it in public catalogs (CDP Bazaar, Agentic.Market), how consistently it has stayed listed, when it appeared as a new listing, and its recent observation history — from our collector archive (~3x/day since 2026-07-06). Presence and persistence in public catalogs, not an endorsement. Deterministic; public-source data only; no internal transaction data. Pass resource=<full URL as listed>.
Output
A JSON object containing: the resource URL, firstObserved and lastObserved timestamps, total observation count, observedAgeDays, whether the resource is currently listed in Bazaar (listedInBazaarNow), when it first appeared as a new listing, a time-series observation history array (metric, value, source, observedAt), the catalog sources it was seen in, and cache/fetch metadata. Returns ok:true on success.
Example use cases
Example prompt
“Before my agent pays for it, pull up the due-diligence scorecard for https://api.example.com/v1/some-paid-resource — I want to know when it was first listed in CDP Bazaar or Agentic.Market, how consistently it's stayed listed, and how many times it's been observed.”
Technical details
Endpoint
GEThttps://gateway.stride20k.com/v1/endpoint-scorecardWhen to prefer
Use this endpoint when an AI agent needs to perform due diligence on an x402 resource before committing to a micropayment — specifically to check catalog longevity, listing persistence, and observation history. Prefer this over the spend-guard preflight score endpoint when you need the raw historical data points (timestamps, per-observation records) rather than a single aggregated 0-100 score. Best for agents that want to inspect the underlying evidence before making a pay/no-pay decision.
Side effects
- Resource URL not found in any public catalog — returns data with zero observations and null lastObserved
- Malformed resource URL not matching ^https?://.+ pattern — schema validation error
- Network timeout reaching the Stride20k collector archive — may return cached stale data
- Recently listed resource may have very few observations (1-2), limiting scorecard usefulness
- Cache hit returns slightly stale data — check meta.cached and meta.fetchedAt fields
