Equip your agentwith any capability.
One integration lets your agent discover and call the right API for any task.
Enabled candidates are verified with real paid calls; live evidence keeps catalog recommendations current.
capability/ n. · as defined by h402 /
A provider-native API contract for whatever your agent needs. Pre-tested, priced per call, ready the moment it’s called. Your agent doesn’t integrate APIs — it mounts h402 once, and every capability comes online.
Call it like a function
Each provider publishes its own documented parameters, defaults, and examples behind one task.
/routes/{provider}/{task}Recommended default
Providers compete on price and live quality. The catalog recommends a default; your client keeps it pinned.
default: ✓ providerSwitch explicitly
Live traffic keeps recommendations fresh without silently changing an active payment or input contract.

Mount h402 in one line
Point any coding agent at the hosted skill: no API keys or provider signups; it handles CLI setup. One mount, and your agent has the full catalog.
The wedge
Four integrations, or four capabilities
Every API used to mean an account, a key, an SDK, and a bill. A capability is just a call.
