x402-reliability-feed

Live reliability feed of x402 endpoints on Base: which services are up, return a valid 402 envelope, and how fast — free-probed across the CDP Bazaar catalog. A real share of listed endpoints are broken/misconfigured; poll ?since=<unix> (or ?health=healthy) to route your agent to endpoints that actually work. Objective measurement, no accusation, machine-readable.

Census of the x402 ecosystem from our daily Bazaar snapshots: which domains launched or disappeared since yesterday, price-median drift, and network mix. ?kind=new|gone for the machine-actionable churn roster, or full pulse with aggregate + timeline. Only a holder of past snapshots can compute churn — objective counts, no quality judgment, machine-readable.

Which Base public RPCs serve a stale chain tip. Every 30s we ask all major public RPCs for eth_blockNumber in parallel and record how many blocks behind the fastest peer each was, plus latency and error rate. An RPC never reports its own lag, so an agent reading a balance from a lagging endpoint cannot tell. Omit ?rpc for the full map; ?rpc=<host> for one.

Why isn't my x402 listing getting discovered/sold? ?domain=you.com returns your Bazaar ranking inputs as cohort percentiles — last-30-day calls & unique payers, staleness, resource count, live health — so you can see where you sit vs the catalog. No args = cohort distribution + zero-call (invisible) listings. The visibility companion to listing-doctor. Descriptive percentiles, not a verdict.

Listed, able to charge, and still not selling? We join the Bazaar catalog with measured on-chain revenue and report the median profile of the top fifth of earners, of everyone earning anything, and of those earning nothing, alongside your own. In our data the top fifth list 14 resources to the zero group one, and write 190-character descriptions to their 370. Correlations across services, not advi

Is your x402 service still listed? The Bazaar removes resources that go without settlement, and no one tells you. We keep a daily snapshot of the whole catalog since June, so we can show whether your domain is present today, how its resource count moved day by day, and how long since each resource was last paid for. In our latest scan 620 of 2,147 domains are no longer present. Measured from our o

Machine-readable map of the x402 service ecosystem on Base: price range, category, endpoint count, live health & latency per service — built from our continuous catalog+reliability scan. ?since=<unix> for newly-launched services; ?category=/?health=/?sort= to filter & rank. Skip scanning the whole Bazaar yourself. Objective facts, machine-readable.

Live feed of freshly-detected malicious addresses on Base — address-poisoning seeders caught via zero-value transfer sprays, updated continuously by our on-chain collector. Poll ?since=<unix> to ingest only new threats into your agent's blocklist. Deterministic, evidence-backed, machine-readable.

Pre-send safety check: is this recipient a known malicious address (caught live on Base seeding address-poisoning via zero-value transfer sprays), or a look-alike of an address you trust? Checks our continuously-updated threat DB + deterministic look-alike logic. Answers an agent's 'is it safe to send here?' before every transfer.
