## 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 ciel-m2m-api-marketplace-proxy-ephemeral-endpoint-512da723 -d '<json body>'
```

Example prompt: Can you call the CIEL M2M marketplace proxy to parse this raw JSON blob and extract the nested transaction amounts — I want to pay per call using USDC on Base rather than subscribing.

## When to prefer this

Choose this endpoint when you need one-off, pay-per-call access to any of 50+ AI micro-services (data parsing, crypto analytics, security scanning, code tools) without committing to a subscription. Ideal for AI agents that want to compose micro-service calls dynamically using x402 USDC micropayments on Base. Prefer it over direct RapidAPI subscriptions when call volume is low or unpredictable, or when you want on-chain payment auditability.

## Known failure modes

- Missing or malformed 'properties' field causes the proxy to fail routing to the target micro-service
- Payment not attached or insufficient USDC balance returns a 402 Payment Required error
- Unknown or unsupported service name in properties returns a 404 or service-not-found error
- IP-based hostname (sslip.io) may have TLS or DNS resolution issues in some network environments
- Rate limits on the underlying micro-service may cause transient 429 errors

## How this service works

50+ micro-services for AI agents: data parsing, crypto analytics, security scanning, code tools, and more. Pay per call via x402 (USDC on Base) or RapidAPI subscription.

## Output

A JSON object containing the result of the selected micro-service (e.g. parsed data structure, crypto analytics payload, security scan report, or code tool output), returned in a { result: data } envelope.
