# Delx Commerce — Robots Directive Merge

> Delx Commerce — Robots Directive Merge is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Merges generic and agent-specific robots.txt directives to produce a unified set of crawling permissions (index/follow/noindex/nofollow)

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 delx-commerce-robots-directive-merge-e557470d -d '<json body>'
```

Example prompt: Merge these two robots directive strings for me — the generic one is 'noindex, follow' and the agent-specific one is 'index, nofollow' — and tell me what the effective combined permissions are.

## When to prefer this

Choose this endpoint when an AI agent or crawler needs to deterministically reconcile two sets of robots directives (generic site-level and agent-specific) into a single authoritative permission set, especially when auditability (via input hash and no-retention guarantee) matters. Prefer it over manual parsing when you need a verifiable, pay-per-use microservice with no signup or persistent data storage.

## Known failure modes

- Input strings exceeding 8192 characters may be rejected
- Malformed or unparseable directive strings may produce unexpected merge results
- Missing both input fields may result in a default or error response
- Payment failure via x402 will prevent the call from completing

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object with the merged boolean result for each directive (index, follow, noindex, nofollow), an overall status ('pass'), evidence including whether input was retained (always false), the SHA-256 hash of the input, and the count of external calls made (always 0). No data is stored or retained after processing.
