How this service works
ForwardLane's Agentic APIs expose the FL Repos Intelligence platform: a code knowledge graph, financial-ontology code mappings, technical due-diligence metrics, code quality scores, security findings, and SWE-bench style evaluation tasks, all computed over 151 private financial-services repositories. Every endpoint is a synchronous read that returns JSON. This server is a pay-per-use, transparent proxy in front of ForwardLane'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'), a priceUsd field always equal to '0' (this lookup is free), a markdown 'guide' string with the matched API contract, live pricing, prerequisites, and actionable next steps, and a 'guideUrl' URI pointing to a wallet-free advisor endpoint for further planning or recovery.
Example use cases
Pre-purchase planning for code quality API
“I want to use ForwardLane's code quality API to score 200 repositories but I'm not sure what it costs or what I need to set up first — can you get me a free quote and step-by-step guide before I spend anything?”
Autonomous agent budget check before execution
“My agent is about to run 500 calls against ForwardLane's repo rankings endpoint with a $50 budget using x402 — can you pull a free quote first so I can review the price and contract before it proceeds?”
Exploring ForwardLane APIs without a wallet
“I don't have a crypto wallet set up yet, but I want to understand what it would cost and what's involved in using ForwardLane's security pattern analysis API for a fintech due diligence task — can you get me the guide?”
Technical details
Endpoint
POSThttps://agents.forwardlane.com/zeroclick/agent/quote?utm_source=zero.xyzWhen to prefer
Use this endpoint whenever an agent or user wants to discover, price, or plan a ForwardLane API purchase before committing any funds or credentials. It is the right first call when the agent lacks a wallet, needs to confirm prerequisites, wants to understand the exact contract, or must present a cost estimate to a human for approval. It is preferable to direct paid endpoint calls when budget authorization is uncertain or when the required payment method is unknown.
Side effects
- 'needs_input' status returned when the goal description is too vague to match a specific API contract
- 'blocked' status if the described task is unsupported or unavailable on the platform
- 'unknown' status when the platform cannot confidently match the goal to an existing endpoint
- 'unsupported' status if the requested capability does not exist in ForwardLane's catalog
- Malformed goal string (too short or too long) causes 400 validation error
- Invalid budgetUsd format (non-numeric or wrong pattern) causes schema validation failure
Input
Schema · Request body

| quantity | integer | Number of API calls, not returned items. Omit when unknown; describe desired output in goal. |
| budgetUsd | string | Total cash budget in USD. A quote does not authorize spending. |
| requirements | string | |
| humanAvailable | boolean | Whether a human is in the loop. False recommends anonymous auth for a new autonomous identity; omit when unknown. Executing a human's request without further interruptions does not by itself mean false. |
| budgetExclusive | boolean | |
