## 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 agents-actionlayer-io-actionlayer-free-seller-api-quote-purchase-guide-660b02a1 -d '<json body>'
```

Example prompt: Before spending anything, can you get me a free ActionLayer quote for running a web scraping task on 50 URLs — my budget is $10 total and I'm using x402 for payment, with no human in the loop?

## When to prefer this

Use this endpoint when you need to plan, cost, or validate an ActionLayer task before committing any budget or requiring a wallet. It is the right first step for any agent or user who wants to understand API contracts, pricing, and prerequisites for a goal — especially when no wallet or credentials are available yet. Prefer this over the paid execution endpoints whenever you need to check feasibility, compare costs, or gather next steps without side effects.

## Known failure modes

- Missing required 'goal' field returns a validation error
- Goal description too long (>2000 chars) is rejected
- Invalid budgetUsd format (non-numeric or too many decimal places) causes a schema error
- Unsupported payment method enum value returns an error
- Status 'blocked' or 'unsupported' in response means the described task cannot be fulfilled by ActionLayer
- Status 'needs_input' means more information is required before a quote can be generated
- Network timeout if the service is temporarily unavailable

## How this service works

ActionLayer runs real-world web tasks end to end: an agent submits a natural-language task plus the end user's email, then polls until it finishes. Flat price per task. Purchases made inside a task are paid by the end user from their own connected wallet with their explicit approval - the per-task fee covers the service only. This server is a pay-per-use, transparent proxy in front of ActionLayer's own API: it handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. The complete verified paid surface is listed at /openapi.json, the source of truth for available operations. Each operation here carries its live price in x-payment-info. Use the operations and details here when they meet your needs. Filtered specs contain only matching operations; if you cannot find what you need here, use search or the service catalog. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits) - some meters include free usage per account before any charge, reserved for agents claimed by a human with a verified email.

## Output

A JSON object containing: a status field (e.g. 'quoted', 'ready', 'needs_input', 'blocked', 'unknown', 'unsupported', 'unavailable'), a priceUsd field always set to '0' (this lookup is always free), a guide string with Markdown instructions detailing the matched API contract, pricing, prerequisites, and next steps, and a guideUrl pointing to a wallet-free advisor endpoint for further planning or recovery.
