Generate length cryptographically random bytes, encoded as lowercase hexadecimal. length defaults to 32 and may be 1 to 4096. Uses the server OS CSPRNG. Returns consumed bytes for reproducible calculation, not proof of their origin. Price: 0.007 USDC per request, including the bounded batch.

Single-signal check: is this website's pricing machine-readable for AI agents? Detects Offer schema with price/availability and pricing-transparency signals. Returns yes/no plus underlying checks and fixes. Useful for procurement and comparison agents.

Is this company or domain legit? Business and domain verification (KYB) for vendor screening, supplier checks and scam or fraud review: domain age and registrar from RDAP, DNS (A/MX/NS), email security (SPF/DMARC) and HTTPS.

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

Point-to-point directions between 2-10 stops by car, bike, or on foot: total and per-leg distance and travel time, plus route geometry as an encoded polyline. Stops can be place names (geocoded automatically) or lat/lon coordinates. Generic travel and delivery routing on OpenStreetMap road data, global coverage. POST a JSON body like: {"stops":["paris","lyon"],"mode":"car"}

American Community Survey 5-year demographics for Scotts Bluff County and each of its ten places, plus a 16-year trend series: population, median household and per-capita income, poverty, median home value, gross rent, housing units and owner/renter occupancy. GET /v1/census.

Full paid x402 diagnostic JSON for a target endpoint.

Conductor mass is calculated from nominal cross-section, core count and length against the material density; for a nominal cross-section this is exact and independent of stranding. Total cable mass and the copper share are returned as a range derived from published manufacturer weight tables per cross-section band, not as a type-test value. Insulation, filler and armour are not modelled individually.

Extract clean, LLM-ready Markdown or plain text from up to 5 public webpage URLs. Removes page boilerplate and returns structured per-URL results for AI agents, RAG ingestion, research and summarization.

Sorts caller-supplied placement opportunities by end time and solves the weighted non-overlapping interval problem exactly with dynamic programming. It does not buy inventory, predict conversion, enforce platform policy, model audience harm or guarantee campaign performance.

Fetch a block header by number, hash, or "latest" on Ethereum, Base, Arbitrum, Optimism, Polygon, or BNB Chain: timestamp, miner, gas used/limit, base fee, transaction count, size. Public JSON-RPC, no API keys. POST a JSON body like: {"chain":"base","block":"latest"}

Applies caller-supplied rename and numeric scale/offset rules to scalar attributes, optionally retaining unmapped fields, then hashes the canonical mapped payload. It does not transfer ownership, call a chain, validate either game, preserve semantics, or authorize asset use.

Brazil's tax transition calendar, year by year from 2026 to 2033: which taxes are in force each year, at what rate, and when PIS/COFINS, IPI, ICMS and ISS are extinguished. The context an agent needs to know whether the tax rule it used is still valid on the date of the transaction. Free sample, no payment: https://api.brazilayer.com/v1/tributos/amostra

CVE fact check, deterministic. Answers "is CVE-XXXX-NNNN real", "is it exploited in the wild", "what version fixes it", "how severe is it". Joins the NVD record (CVSS score, vector, dates), the CISA KEV catalog (actively-exploited flag, remediation due date, ransomware use), and OSV (affected packages + fixed versions per ecosystem). No LLM. Distinguishes "not a known CVE" from "registry unreachable" — never a false not-found.

Pixel-accurate PNG screenshot of any live web page, rendered in a real browser at a chosen viewport width, viewport-only or full-page. Returns base64 PNG. Use it when an agent needs to SEE a page: visual verification of a deploy, layout and design capture, confirming a rendered chart or map, or feeding an image to a vision model that cannot read HTML.
