How we rank

The headline score is the average of six 0-100 axes computed only from each API’s published, sourced fields: agent-friendliness, pricing transparency, setup speed, docs quality, procurement ease, and trust readiness. An unknown signal scores 0 for its axis - we credit what’s confirmed, never guess. The score is one input, not the verdict: we lead with each pick’s trade-off, and where a job has only one real option we say so rather than crown it. Full method on the methodology page.

Why trust apio

• ✓ Every field cited. Each profile links the source for every claim - check us.
• ✓ Public audit log. Every change to this data is recorded per field, with who changed it and why.
• ✓ Published, deterministic methodology. The score is a formula over the same fields you can see - recompute it yourself.
• ✓ Zero affiliate links, zero ads, zero paid placement. Money never moves rank.
• ✓ No reviews yet - and we say so rather than synthesizing them.
