# Best Coding agents — API access

> Source: https://theagentsindex.com/best/coding-agents/api (curated, quality-gated, re-verified)

16 of 28 coding agents have a confirmed yes for “API access”. 8 are qualified or tier-scoped, 4 are confirmed no, and 0 remain not established. Only confirmed yes answers appear in this set; an unknown is never treated as a negative.

API access splits into two different jobs here: a few of these agents expose an API so you can drive them programmatically from your own pipeline or CI (Claude Code, OpenCode, Zot), while others expose one so an agent can be embedded in a product or triggered from existing tooling rather than run interactively (Devin, OpenHands). Check which job you actually have before picking from this list.

## Methodology

Projected from the live listing datasheets using the tenant’s “Can you drive it from your own stack?” axis. Membership requires a sourced yes; partial and unknown answers are reported above but excluded from the ranking. This page carries an editor’s written angle rather than a measured difference: at this category size no difference from the rest of the category reaches significance. Entries retain the directory’s paid-tier ordering, visibly labelled on every promoted card.
