Performance x402 offerings

Return measured end-to-end fetch timing. Only public HTTP(S) targets are accepted; JavaScript is not executed. Pass url as an absolute public HTTP(S) URL. Keep fresh=false to reuse cache; set fresh=true only when a new upstream fetch is required.

Website uptime and change check: is this URL up right now, and has the page changed? Fetches the URL and returns the HTTP status, Last-Modified and ETag headers, a SHA-256 fingerprint of the content, and whether it changed versus a hash you pass in. Use it to check a site is live, detect stale data, monitor a page for changes, or decide whether to invalidate a cache before your agent acts on what it says. Returns a signed attestation.

Probe an agent-payable HTTP endpoint for current availability, latency, HTTP status, x402 challenge support, and response-schema validity.

Check any public URL: status code, latency, final URL after redirects, and response headers. The uptime primitive for agent monitors.

One-shot health probe for any endpoint: HTTP status and latency, TLS certificate issuer and days-to-expiry, response size, security-header audit (HSTS, CSP, X-Content-Type-Options, X-Frame-Options) and named issues (SLOW_RESPONSE, CERTIFICATE_EXPIRING, SERVER_ERROR_STATUS). Call it on a schedule and you have uptime monitoring for a fraction of a cent.

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 c…

Measured uptime, price and payment evidence for 19,021 agent services. Reliability, not quality.

Forecasts cognitive load for an agent fleet over a short horizon and returns a one-pass task reassignment plan before overload. Machine clients pay $0.05 USDC (x402, Base L2) per forecast. Humans: https://agentpaystore.com/pclas/

Probe a GET endpoint several times and report status codes and latency statistics (min/avg/max). The cheap way for an agent to verify an API — for example one found on the x402 Bazaar — responds before spending real money calling it. Use this when an agent needs to status and latency stats — test an API before relying on it.

Runs a standard profiling job for an AI agent and returns profiling results.

Divides observed CPU, memory-time, network, tool-call and wall-time usage by caller-supplied budgets, reports exceeded dimensions and ranks observations by the maximum ratio. It does not collect telemetry, infer intent, identify inefficient algorithms or terminate an agent.

Profiles CPU/GPU, memory, token, and runtime usage of AI model runs to estimate resource consumption and costs.

Performs comprehensive URL health checks, measuring response time, status code, security headers, and TLS/SSL certificate validity. Route: GET /paid/health-check?url=https://example.com. Ideal for automated monitoring and endpoint auditing.

Measure website response latency, payload size, compression, caching, and performance signals for a public URL.

Creates and verifies hash-only latency SLA evidence for paid agent tools.

Calculate p50, p95, p99, mean, min, and max from bounded latency samples. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reli…

Server Timing Parse: Server Timing Parse parses bounded Server-Timing metrics and durations from bounded caller-supplied values without an external provider. Call Server Timing Parse before accepting…

Inspect URL reachability, status, latency, and key headers for $0.001 USDC. Call when you need a cheap uptime preflight before paying a heavier fetch—not a full page extract and not a crawl. Returns …

Measure achieved reliability against an SLO target from good and total events. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production…

Compare observed latency against an SLA threshold in milliseconds — call when comparing observed latency to an SLA threshold. Use for SRE/ops math agents buy from broad utility catalogs: SLA, error b…
