Agent-readiness dimension

Idempotency

9 of 139 agent-readiness points 6.5% of the agent scoregraded — partial credit idempotency

Mutating operations accept an idempotency key. Agents retry; without idempotency a retry double-charges a card, sends a message twice, or opens a duplicate ticket. Full credit requires the parameter to appear on POST / PATCH / PUT operations in the contract — the difference between a provider saying they support it and a contract an agent can act on.

232at full credit
579at partial credit
1,001not applicable
1,001 providers are scored na on this dimension, not zero. A read-only surface carries no write hazard to mitigate, so since rubric 0.12 this dimension leaves their denominator entirely rather than handing them a zero for something they cannot have. Every number on this page is over the 26,503 providers it does apply to.

How it is scored

One signal, read from what the provider publishes, worth 9 points of the 139 in the agent-readiness score.

Grades and what each earns

This dimension is graded rather than pass/fail: how the signal was evidenced decides what fraction of the points it earns.

Move this number. Every provider in the catalog is profiled from a public repository at github.com/api-evangelist/<provider>, and each check above names the exact artifact it reads. Publish the artifact, open a pull request, and the next scoring run picks it up — no gatekeeping and no fee. The full rubric is at apis.io/rating/, and prioritized profiling is the fast lane if you would rather have it done for you.

Scored on rubric v0.17.2 across 27,504 providers · lists rebuilt 2026-09-01 · capped at the top 500 per page.
