Create paid render quote

fvs_create_paid_render_quote

Create a no-account Link payment quote for an FVS render.

The backend returns HTTP 402 payment details as data: `payment_url`,
`status_url`, `claim_token`, `amount_cents`, `currency`, and a raw
`www_authenticate` challenge. Pay `payment_url` with Link's MPP flow, then
poll with fvs_get_paid_render_status. Local file uploads are not available
in paid quote mode; use public HTTPS `upload_urls` when assets are needed.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`request`	Yes	Required render request object used for the paid quote. Include name. project_mode must be one of scene, music, or custom. Use assets[].purpose for asset intent. Usually include screenplay, instructions, shot_count, duration, and resolution.
`upload_urls`	No	Optional public HTTPS reference asset URLs. Each object can include url and filename; filename should match request.assets[].filename.

TDQS

A4.4/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description discloses key behaviors beyond annotations: the backend returns HTTP 402 payment details (payment_url, status_url, claim_token, etc.), requires an external payment step via Link's MPP flow, and disallows local file uploads. This adds meaningful context to the non-idempotent, non-read-only annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is three sentences in a logical order: purpose, payment flow, and asset constraint. Every sentence adds value with no repetition or fluff, and the key purpose is front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the presence of an output schema and annotations, the description adequately covers the workflow: creation, payment, polling, and asset handling. It references the necessary sibling tool for follow-up and does not need to explain return values. Slightly more detail on when to use this vs. fvs_submit_render would make it complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

While the schema already provides 100% parameter coverage, the description adds important semantics for upload_urls: local uploads are not supported and public HTTPS URLs must be used for assets. This clarifies the parameter's purpose beyond the schema description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool creates a 'no-account Link payment quote for an FVS render,' using a specific verb and resource. It also differentiates from sibling tools like fvs_submit_render by focusing on the payment quote aspect and mentions polling with fvs_get_paid_render_status.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It provides explicit guidance: pay the returned payment_url and poll with fvs_get_paid_render_status, and use public HTTPS upload_urls since local file uploads are not available. It lacks an explicit contrast with fvs_submit_render but gives clear usage context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
