Help & FAQ

Everything you need to get started with SheetsData and troubleshoot common issues.

Getting Started

  1. Create an account at sheetsdata.com/signup
  2. Get your API key from the dashboard
  3. Configure your MCP client — follow the step-by-step instructions on the setup page
  4. Make your first call — use search_parts to find components by keyword or part number

Tools Overview

SheetsData exposes MCP tools that your AI agent calls automatically. Here's what each one does.

Free tools

search_partsFree

Search for electronic components across multiple distributors (JLCPCB, Mouser, DigiKey). Returns pricing, stock, and datasheet availability.

search_datasheetsFree

Semantic search across all extracted datasheets. Great for spec-based discovery, e.g. "low-noise LDO with PSRR above 70dB".

prefetch_datasheetsFree

Batch warm-up extraction for up to 20 parts. Fire-and-forget — the agent can continue working while datasheets are extracted in the background.

check_extraction_statusFree

Poll extraction progress after a prefetch or read_datasheet call to see when a datasheet is ready.

Paid tools

get_part_details4¢

Detailed part info including parameters, datasheet status, and an optional prefetch trigger.

read_datasheet6¢

Read specific sections from an extracted datasheet, or run a semantic search within it.

compare_parts10¢

Side-by-side comparison of two or more parts with key specs and datasheet status.

check_design_fit10¢

Validate your operating conditions (voltage, current, temperature) against datasheet limits.

find_alternative10¢

Find drop-in or functional alternatives for a given part number.

analyze_image8¢

Vision AI analysis of datasheet images — graphs, package drawings, pin diagrams, and schematics.

See full pricing details on the pricing page.

Common Issues

"Insufficient balance"

Your prepaid balance is too low for the requested tool call. Top up your account at Dashboard → Billing.

"Rate limit exceeded"

You've hit your plan's request-per-minute limit. Wait a moment and retry, or contact support to discuss higher limits.

"Extraction failed"

The PDF extraction for a datasheet did not complete successfully. You can retry from Dashboard → Extractions. If the problem persists, let us know and we'll investigate.

"No datasheet found"

Not all parts have datasheets available online. Try searching for the base part number (e.g. "STM32F446" instead of "STM32F446RCT6"), or check if an alternative part number is listed by the manufacturer.

Billing & Plans

SheetsData uses a prepaid balance model — add funds and each tool call deducts from your balance.

  • Trial — Free signup credit to get started. 10 requests per minute. Free tools always work, even with zero balance.
  • Pro ($39/mo) — Monthly minimum includes $39 in usage. Overage billed at per-call rates. 60 requests per minute. Auto-recharge available.
  • Enterprise — Custom pricing, SSO, audit log, priority extraction, and volume discounts. Contact us.

Top up anytime from Dashboard → Billing.

API Keys

  • Create and manage keys from Dashboard → API Keys.
  • Keys are shown only once at creation — copy and store them securely.
  • Revoke any keys you no longer need to keep your account secure.
  • Never share API keys, commit them to public repositories, or embed them in client-side code.
