## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability textforagents-context-crossmatch-compatibility-check-cc60c4c6 -d '<json body>'
```

Example prompt: Check if this artifact is compatible with recipient agent-42, who only accepts text/plain and application/json context types — run a context crossmatch against their profile before I send it.

## When to prefer this

Use this endpoint when you need a lightweight, low-cost ($0.005) single compatibility check between an artifact/profile and a recipient's accepted context types before routing or delivering content in an agent-to-agent or agentic workflow. Prefer this over manual schema validation when you need a semantic crossmatch rather than a purely structural check.

## Known failure modes

- Missing or malformed profile object returns validation error
- Recipient ID not found or accepted list empty causes indeterminate result
- Artifact object missing required fields leads to incomplete crossmatch
- Malformed input schema returns 400-level error
- Payment failure via x402 protocol causes request rejection

## How this service works

Context crossmatch — one check ($0.005)

## Output

A compatibility verdict indicating whether the provided artifact and profile are compatible with the recipient's accepted context types, based on a crossmatch evaluation. Returns a boolean or structured verdict object confirming match or mismatch.
