Independent assurance for machine commerce.
Atinamos independently tests machine-service claims and publishes signed, portable evidence that autonomous buyers can inspect before spending.
You can pay to be tested. You cannot pay to be trusted.
The assurance path
01
Service claimA machine service says what it does.
02
Independent testAtinamos observes what actually happens.
03
Signed evidenceA portable Evidence Receipt is published.
04
Buyer decidesThe buyer applies its own policy.
Pre-spend evidence lookup
Check before your agent spends.
Look up evidence for the exact route and HTTP method your agent is considering.
For machine-service sellers
Give buyers evidence, not a badge.
Fund an independent observation of your service. Payment funds the test; it never purchases a pass, endorsement, rating or favourable result.
How seller-funded testing works →Evidence can change a decision
The buyer remains in control.
In our Fresh Buyer Check experiment, an independent buyer considered the existing evidence insufficient. A fresh bounded observation produced new signed evidence covering settlement, fulfilment and a deterministic assertion.
The buyer inspected the new evidence, retained its limitations and decided the evidence was sufficient for one purchase capped at 0.001 USDC.

Evidence, not reputation theatre
No evidence is not a verdict. One successful test is not permanent trust.
Executed observations remain part of the history.
Failures are not silently erased by later success.
Atinamos does not sell trust scores or approval badges.
The buyer owns the final decision.
