}Trust check before paying an unfamiliar x402 service, by pay_to address and/or service URL. Combines our own availability monitoring of the service's x402 endpoint (30-day uptime, last check, observed payTo/price and drift between our measurements), on-chain USDC payment history to the address on Base (2-day window), and EU regulatory status of the domain (MiCA-authorised or ESMA warning list). Factual only — no scores; not being monitored is not negative, presence is no endorsement.
| Argument | Type | Description |

}Free with a feed_handle from crypto_feed_subscribe: every published advice change since your cursor, across all covered coins — new signals, classification flips (previous_classification vs classification), status/score/entry-zone changes.

}Subscribe for 30 days to the change feed behind /crypto/scan: one cursor over the upstream advice ledger, all coins at once. Returns a handle and a cursor; polling is then free and unlimited: /crypto/feed/since returns every published change since your cursor — new signals, classification flips, status changes (PUBLISHED/STALE/INVALIDATED), score and entry-zone changes. Be first to know when the market state flips; the full advice per signal stays a separate paid call.

}Measured track record of the strategies behind /crypto/verdict, resold from the upstream signal system. Give a window in days (default 30, clamped 1..365); returns per strategy the number of trades, wins, win rate and average net return over that window, with the measurement start. A factual measurement over a short window (wide error bars), not investment advice. Cheap showcase for the paid verdict endpoint.

Pick layer long|daytrade|both. No fresh verdict for the requested layer means 400 and no charge — you only pay for an actual, still-valid verdict. Factual model output, not investment advice.
| Argument | Type | Description |
|---|---|---|
| coin* | string | Coin/product id, e.g. 'BTC-EUR' (see supported coins in the error on an unknown coin) |

}File what you want to buy from an agent-facing API and cannot buy today. Optional kind is typically one of coin, country, vies_country, monitor_host, sms_service — free-form values possible.

Real measurements, never fabricated; short windows have wide error bars. Paid per request.

}Google Places (local businesses with rating, address and phone number) for AI agents at $0.010 per call, from the same Serper.dev source as /web/search. Send a query, get back compact JSON: top places with position, title, address, coordinates, rating, rating count, category, phone and website. Tune with num (1-10 results), country and language (2-letter codes). Zero results is a valid, honest answer. Pay per call in USDC on Base, no account, no API key.

}Search and read in one call: a web search plus the full page text of the top results, for $0.030 — cheaper than a separate search and reads. Send a query, get back results (position, title, url, snippet) enriched with the page's readable content as markdown or text. You get the number of pages you asked for: a paywalled result is replaced by the next readable hit, and anything still missing falls back to the snippet, labelled content_source.

}What are agents asking for that they cannot buy yet, aggregated over 30 days. From our own measurements: calls we rejected on an uncovered value where the caller had already presented payment (kind is typically coin, country, vies_country, monitor_host or sms_service — free-form values possible), free requests filed by agents, and settled $0.01 intents. Demand at one provider, not a network-wide picture. Aggregates only: no wallets, no free text, no subject ids.

}Subscribe for 30 days to a change feed of the x402 network, from our own probes (~2 per host per day, 1500+ hosts). Returns a handle and a cursor; polling is then free and unlimited: /x402/network-feed/since returns all that changed since your cursor (down/up, payTo drift, price drift, manifest gained/lost), and /x402/network-feed/check takes up to 50 hosts you are about to pay and returns their last observed status, payTo and price plus changes. Facts only, no scores and no catalogue data.

}Daily state-of-the-network report on the x402 ecosystem, built exclusively from our own probes (~2 per host per day): how many hosts we monitor, share of probes returning a valid 402 over 24h and 7d, host status breakdown (ok_402, HTTP errors, unreachable), manifest coverage, and counts of observed changes over 24h and 7d (up/down transitions, payTo drift, price drift, manifest gained/lost) plus the hosts that moved today. Regenerated once per day. Facts only — no scores, no catalogue data.

}Full reliability report on one x402 service from our own availability monitoring (~2 probes/day per host): daily probe series over 30 days (probes, ok, avg/max latency), uptime 7d/30d, all observed change events (up/down transitions, payTo drift, price drift, manifest appearing/disappearing) and the payment details as last observed in the service's own 402 responses. Returns 400 host_not_monitored (no charge) when we have no history for the host. Facts only — no scores.
