Cheapest real end-to-end test of your pay-per-call (HTTP 402) client: pay US$0.002, get back what was paid (payer, amount, network, timestamp) and the text you sent; the settlement receipt is in the PAYMENT-RESPONSE header. A free trial call returns paid_usd 0. Use it to check a wallet, a client library or a facilitator before buying something bigger.

Current time from a trusted server: UTC ISO timestamp, Unix seconds and milliseconds, and the time in an optional IANA time zone.

Fresh random identifiers from a secure generator: UUID v4 (up to 50) plus random hex bytes.

Hash a text with SHA-256, SHA-384, SHA-512 or SHA-1: hex and base64 digests, for checksums, deduplication and content fingerprints.

Decode a JWT without verifying it: header (algorithm, key id), payload claims, and issued, not-before and expiry times with whether it is expired now.

Cryptographically secure random integers in a range you choose (unbiased), up to 1,000 per call.

Explain a cron expression in plain English and list its next run times in any time zone (5-field cron, names like MON/JAN, ranges, steps and @daily-style macros).

Public holidays for a country and year, and optionally the number of business days between two dates (weekends and national holidays excluded).

Encyclopedia summary of a topic: title, one-line description, the lead paragraph as plain text, thumbnail and article link, in any language edition.

Exact finance maths: loan repayment and total interest, compound growth with regular contributions, NPV and IRR of cash flows, and ROI with annualised return.

Repair broken JSON (typical of model output) into valid JSON: removes code fences, comments and stray text, fixes single quotes, unquoted keys, trailing commas, Python literals (True/None) and truncated output. Optionally checks the result against a JSON Schema.

Convert CSV (or TSV) to JSON rows with the header row as keys; numbers and true/false are typed, quoted fields and embedded newlines handled. Up to 50,000 rows.

QR code for any text or link, as a ready-to-use SVG image (and a data URI), with error-correction level and size options.

Weather now and hour by hour for the next 1-48 hours at any latitude and longitude: temperature, wind, humidity, cloud, precipitation and conditions.

What AI agents look for that isn't served yet: tools, methods and paths that visiting agents requested at an open agent marketplace and got nothing, ranked by how many distinct agents asked (scanner junk excluded). Build what's missing.

Search scholarly papers: title, year, first authors, venue, citation count, DOI and a free full-text link when one exists, most relevant first.

Health check for an npm or PyPI package before your agent installs it: latest version and release date, weekly downloads (npm), licence, repository, and known security vulnerabilities for a given version.

Search official US recall and enforcement reports for food, drugs or medical devices: product, reason, classification (severity), firm, status and date.

Find a tool for a job across thousands of public MCP servers we have visited and checked: search by capability and get matching tools with their server, endpoint and description, best matches first.

Find live autonomous AI agents by capability: agents from the ERC-8004 agent registry and A2A agent cards whose endpoints answered when checked. Returns names, descriptions and A2A/MCP endpoints.
