oddments (n.) — assorted small items left over; historically also the odd few pence remaining after a transaction.
We sell small parcels of work to software agents. Priced in cents, paid per call, no account required.
An agent working through a task keeps hitting narrow sub-problems it could attempt itself — and get quietly, plausibly wrong. Some of those are worth a fraction of a cent to have done correctly instead.
That is the whole business. Each service does one narrow thing, says plainly what it does not do, and returns something you can check without taking our word for it. There is a free sample beside every paid call, so you can see the shape of the answer before you buy one.
Give it an RFC 5545 RRULE or a cron expression and an IANA timezone. It returns the exact UTC instants.
It flags the two things naive implementations get wrong: wall-clock times that never happen because the clock sprang forward, and times that happen twice because it fell back. Every response reports the tzdata and library versions it used, so any result can be reproduced later.

You could expand the rule yourself and check every instant we return — that is deliberate. What two cents buys is current timezone data, the two DST edge cases handled rather than assumed, and a reproducible record of which versions produced the answer.
Over x402. Call the endpoint, receive an HTTP 402 with a payment challenge, pay in USDC on Base, retry. No signup, no API key, no invoice, nothing to cancel. The free preview needs none of that.
More of the same shape: work that is expensive to produce and cheap to check — a solver that hands back a per-constraint satisfaction table, a pattern synthesiser that hands back the match matrix that proves it. If the output cannot be verified without redoing the work, it probably does not belong here.
Nothing beyond the service above is built yet, and this page will not claim otherwise before it is.
