payment-ready until 2026-10-30

Watch a public web page and get a signed webhook the moment a condition becomes true (restock, price drop, appointment slot, launch, content change, HTTP status, a new URL in a sitemap, a new item in an RSS, Atom, or JSON feed); a half-cent recheck that says whether a page changed since the hash you hold; timed wakeups; a durable callback inbox for AI agents whose session ends before the world answers.

Endpoints and prices

Current paid endpoints; minimum quoted prices in USD where available; first capture dates in UTC
Method	Path	Description	Price	Network	Asset	402 channel	Captured
GET	/v1/checks	Fetch a public URL once, right now, and evaluate a condition against it (keyword, CSS selector, JSON path, price threshold, content hash, or HTTP status). Returns matched:true/false with the extracted value and a short evidence excerpt. Synchronous; typical response under 3 seconds. $0.01 per check.	$0.01	Base+Sol	USDC, UNKNOWN	header	since 09-08
GET	/v1/inbox	Open an inbox: a capture URL that holds anything POSTed to it for up to 7 days (an A2A push, an MCP task completion, a GitHub or payment webhook, another agent) and forwards each message to your webhook in a signed envelope, or lets you poll. The durable recipient a finished session cannot be. Up to 200 messages of 64KB, optional shared-secret header. One-time $0.10.	$0.10	Base+Sol	USDC, UNKNOWN	header	since 09-08
GET	/v1/recheck	Recheck a URL: has this page changed since the hash you hold? One fetch, one sha256 of the visible text (or of one CSS selector's text), compared with the hash from your last look. Returns changed true/false, the new hash, and a short excerpt, so you only re-read a page into your context when it actually changed. Works on HTML and JSON. GET with query parameters or POST with a JSON body. Synchronous, $0.005, no account needed.	$0.005	Base+Sol	USDC, UNKNOWN	header	since 09-14
GET	/v1/wake	Schedule a wake: Stumble calls your webhook at a time you set (up to 30 days ahead), echoing back a JSON payload you stored, signed with your one-time secret and retried on failure. Sleep for agents whose session will be gone by then: no process to keep alive, no polling, no cron. One-time $0.01, no account needed.	$0.01	Base+Sol	USDC, UNKNOWN	header	since 09-08
GET	/v1/watches/fast	Create a fast watch: Stumble polls a public URL every 60 seconds for up to 7 days and notifies your webhook (or lets you poll for free) the moment a condition becomes true (keyword, selector, JSON path, price, content change, HTTP status, new sitemap URL, new feed item). One-time $0.50, no account needed. Ideal for restocks and appointment slots.	$0.50	Base+Sol	USDC, UNKNOWN	header	since 09-08
GET	/v1/watches/sniper	Create a sniper watch: Stumble polls a public URL every 10 seconds for up to 48 hours and notifies your webhook within seconds of a condition becoming true (keyword, selector, JSON path, price, content change, HTTP status, new sitemap URL, new feed item). One-time $2.00, no account needed. Ideal for drops and on-sale moments where seconds matter.	$2.00	Base+Sol	USDC, UNKNOWN	header	since 09-08
GET	/v1/watches/standard	Create a watch: Stumble polls a public URL every 15 minutes for up to 14 days and notifies your webhook (or lets you poll for free) the moment a condition becomes true (keyword, CSS selector, JSON path, price threshold, content change, HTTP status, a new URL in a sitemap, a new item in an RSS, Atom, or JSON feed). One-time $0.10, no account needed. Ideal for price drops, release feeds, and slow-moving pages.	$0.10	Base+Sol	USDC, UNKNOWN	header	since 09-08

How the score works

What the score read on this service: status online, 100% uptime 30d, 484ms response p95, x402 compliance 14 of 14, $0.005 price against the category, on-chain traction measured. Each of those is measured, and each is published in full below.

The score comes from our own monitoring, never from reviews, operator claims, or a language model: reliability, x402 compliance, price against the category, a deterministic risk flag, and a small on-chain traction term, weighted by ranking generation 3. It is not placement anyone can buy: the paid verify tier is reported beside it and is not one of its inputs. Every component below stays published and read-only.

Bands on the 0 to 100 measured score: strong at 93 and above, solid from 75, mixed from 55, weak below 55. Price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, so the score places a service in its own field.

It is a score inside AI, and only there: price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, which here means 190 listings, this one among them: the same 190 the position above is counted against. When the two differ, the field is the wider one, because a listing we have measured too little of to rank still sits in the field the price and the speed are normalized over. The same service in a different field would read differently. The same engine answers GET /api/v1/best, and asked for a different pool (the whole directory, or another filter) it returns a different number for this service under this same ranking generation. Neither is more correct: they answer different questions, and the methodology states which is which.

Settled via coinbase ($0.03, 5 tx). Traction is a conservative undercount; first settlement seen 2026-09-03.

All measured facts

What it does

Stumble is a listed x402 AI API. Captured payment terms name Base, Solana. Monitoring and settlement figures below describe the observations available to this directory; an unpaid HTTP 402 check does not prove that a paid call will deliver.

Assessment computed at 2026-10-23 14:23:01 UTC. Latest service check observed at 2026-10-23 14:29:20 UTC. Service data JSON · Measurement methodology.

Page rendered at 2026-10-23 14:32:52 UTC. This response time is separate from the observation and computation times attached to each measurement.

Latest endpoint observation: 2026-10-23 14:29:20 UTC. Latest price capture: 2026-10-23 14:29:20 UTC. Prices are recorded quotes, not a promise of availability. Token assets and payment terms are listed separately. Endpoint data JSON · Price history JSON · Measurement methodology.

Assessment computed at 2026-10-23 14:23:01 UTC. Uptime uses the stated daily-rollup window; response times are in milliseconds, compliance is passed/evaluated checks, and traction is a measured settlement floor. The comparison score is out of 100 within this category. Assessment JSON · Measurement methodology.

Observed daily coverage: 2026-09-24 to 2026-10-23 UTC. Daily monitoring and settlement rollups do not expose their computation time; a bucket date is not an update timestamp.

Assessment volume uses the latest 30d assessment. Over time sums daily address snapshots, rounded to cents and refreshed separately. The two sources can differ in timing, precision and shared-address attribution. Amounts use cents for comparison; known sub-cent values keep up to 12 significant digits. The exact stored assessment value is shown above.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.

Top buyer share lowers the on-chain traction part of the ranking score behind this page's verdict and /best, by up to half when one address holds all 30d volume. The Recommended and Highest volume sorts of the services list do not use it; they use the Concentrated volume rule instead.

Scores: one day per column, 09-24 to 10-23*, on the columns of Response time. Uptime held below 100% on some days in this window, including any partial day. Daily readings remain in the Uptime strip and Values. The checklist grew from 11 to 14 checks on 2026-07-28, before this window. Pillar lines use their own low and high. Exact dated readings are available in each readout and in Values.

Each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/stumble/price, /scores, /volume and /buyers.

Values

* today so far, partial (UTC).

The uptime summary counts completed UTC days only. The strip, readouts and table retain today's partial reading.

Daily snapshot total, 30d: $0.03, peak $0.03 on 09-24. The visible 30d total in Traction comes from the latest assessment. These sources can differ in their window, refresh time, cent rounding and shared-address attribution.

Daily address snapshots: 2026-09-24 to 2026-10-23 UTC; * today so far, partial (UTC). Daily snapshots store cents. A recorded $0.00 with settlements cannot distinguish exact zero from volume rounded away. Lost precision is unavailable here.

Settlement volume uses the stored USD valuation of tracked payments; it is distinct from token quantities. USD-pegged assets are valued at 1 USD per token in these rollups. The measured settlement floor does not cover all payments to this service.

Assessment history last recorded at 2026-10-23 14:23:01 UTC. Each UTC day uses its last recorded run; missing readings stay unmeasured. Assessment history JSON · Measurement methodology.
