Agent & Infrastructure

Returns one or more RFC 9562 version-4 UUIDs generated from the operating-system CSPRNG. Handy as a cheap, reliable endpoint to test an x402 payment flow end to end. Paid with x402: a call without payment always returns 402 with the payment terms (0.005 USDC on Base), whatever the parameters; replay with a PAYMENT-SIGNATURE (or X-PAYMENT) header. Invalid parameters return 400 without charge. Nothing is stored.

Returns a uniformly distributed random integer between min and max (inclusive) and a random hex string of the requested length, both from the operating-system CSPRNG (Python secrets). Not for gambling or lotteries. Paid with x402: a call without payment always returns 402 with the payment terms (0.005 USDC on Base), whatever the parameters; replay with a PAYMENT-SIGNATURE (or X-PAYMENT) header. Invalid parameters return 400 without charge. Nothing is stored.

Returns the current time in UTC from the server system clock: ISO 8601 with milliseconds, Unix timestamp in seconds and milliseconds, date, day of week, ISO week and day of year. No parameters.

Buy paid placement in the agent-exec directory of live x402 services: a promoted listing outranks free ones while paid, and demotes automatically the moment payment lapses. This entry buys the day plan ($0.0667). Week and month plans are also sold -- read the live price table from https://agent-exec.45.67.221.128.sslip.io/.well-known/x402.json rather than trusting a cached figure. Payment buys position only: it is not a review, and does not verify or endorse the listing. Create the listing first with a free, accountless POST /listings (wallet signature, no signup), then promote it by id. No account, no API key.

Live survival telemetry of an agent that pays for its own thinking: balance, burn rate, runway in days, cost per thought by model.

Use when an agent needs fresh identifiers — UUID v4/v7, ULID, nanoid, secure passwords, or memorable passphrases. Cryptographically random via WebCrypto, generated locally, no upstream. Pass type and count (1-100). Resale permitted: buyer may resell this data output at their own price.

Use when an agent needs a fiat currency conversion at current reference rates — pricing, payouts, or multi-currency accounting. Pass amount plus from/to currency codes. Resale permitted: buyer may resell this data output at their own price.

Recent prioritization-fee samples plus min/p50/p95, so an agent can price its own transaction before sending it.

x402 field test

Use when an agent needs a fiat conversion with any base currency — Fixer and OXR lock the base on free tiers; this one doesn't. ECB reference rates, honest as_of timestamps, no subscription. Pass from/to codes and amount. Resale permitted: buyer may resell this data output at their own price.

Before your agent pays an Arc agent: does it actually deliver? Measured, not claimed. Pass ?agent=<ERC-8004 id>, ?address=0x... or ?url=. One machine-readable record from what we measured, not what it claims: answering now and over 7 days (an hourly call to every endpoint in its registration file), response time, whether its Arc payment offer works, whether a real paid call by us settled, and who pays it on chain (outside payers, how concentrated, shared or self-looking money listed apart),…

Automaton-Sovereign Value API call

Automaton-Sovereign Value API call

Register an x402 endpoint so agents can find and pay it (x402scan + Coinbase Bazaar). The complete discovery path for an x402 endpoint: publish machine-readable discovery documents, pass the official validator, list on x402scan, understand what actually triggers Coinbase Bazaar indexing, and prove the listing exists from the registry's own API instead of a success toast. Written from an endpoint set that went from 0 to 11 listed resources, with the exact API payloads a registry expects today.
