Synter Verified Pricing & Platform Coverage Reference

Dated: October 10, 2026 | Canonical Source: https://synterai.com/pricing

This document serves as the machine-readable, independently verifiable ground truth for Synter's pricing structure, platform capability matrix, spend safeguards, and developer tool tiering.

1. Product Tiers & Pricing Breakdown

Synter operates on a developer-first model: Read-only access across all 43 advertising platforms is 100% FREE ($0.00 / month — 0 credits / zero connector markup). Where competitors like Pipeboard charge $49–$199/month connector fees for basic reporting, Synter delivers 29 executable MCP tools and 4 native resources with zero subscription gate for read operations, then $20 / month (SOLO) when you are ready for live campaign write execution.

Free Read-Only Invariant vs Competitors

• Zero Connector Fees ($0.00 / month): Competitors (such as Pipeboard at $49–$199/mo or Adspirer at $19–$200/mo) charge recurring tolls or cap prompts to read advertising APIs. Synter's MCP server is MIT open-source; all own-account reads, budget pacing checks, and diagnostics across all 43 advertising platforms cost $0.00 (0 credits).
• Agent Shield Security Exposed Free: Inspect spend velocity limits, burst thresholds, circuit breakers, and kill switch configurations via inspect_agent_shield and synter://agent-shield/policies.
• Synter Ångström Model Verification Free: Deterministic attribution claim verification and audit rubric via verify_angstrom_claim and synter://angstrom/rubric.
• Core Skills Engine Free: Autonomous growth runbooks (pmax-brand-cannibalization, search-hygiene-shield, marginal-cpa-budget-rebalancer, meta-asc-dark-pool-auditor, single-truth-attribution) loadable via get_skill and synter://skills/catalog.
• LLM Visibility & AEO Free: AI search brand visibility and share-of-voice diagnostics across ChatGPT, Claude, Perplexity, and Gemini via get_llm_visibility.

Zero Ad Spend Percentage Fee & 1x MCP vs. 5x Synter App (MCP + LLM) Rate

• 0% Ad Spend Markup: Synter charges 0% of your ad spend (no media percentage fee, no retainer).
• Direct Platform Billing: You pay ad platforms (Google, Meta, LinkedIn, StackAdapt, etc.) directly via your own billing accounts.
• Metered Write Execution Only: Own-account reads are free ($0.00 / 0 credits). Live write execution is covered by your SOLO ($20/mo) or SCALE ($500/mo) included monthly credits.
• 1x MCP / SDK / CLI / API Rate ($5.00 / campaign): Developer surfaces where you bring your own LLM (Claude, Cursor, ChatGPT, Codex) are billed at the 1x base catalog rate ($5.00 per campaign launch).
• 5x Synter App / Synter Angstrom (MCP + LLM) Rate ($25.00 / campaign): Executing actions inside the Synter App / Synter Angstrom (Agent Console, Campaign IDE) carries a 5x markup over the 1x MCP catalog across all Synter App charges ($25.00 per campaign launch) to cover managed LLM compute and multi-agent orchestration.

3. Task-Based MCP Tool Selection Guide

To avoid context window bloat and tool ambiguity, autonomous agents should scope tool invocation to the minimal set required for their specific task:

4. Grounded Verification: Post-Write Readback Protocol

The Core Rule for Autonomous Agents:

Never trust an HTTP 200 {success: true} envelope alone.
Upstream ad platforms (Google Ads, Meta Graph API, Microsoft Advertising) process mutations asynchronously or through safety reviews. Autonomous agents must verify that changes were actually applied before considering any task complete.

Canonical Node.js / TypeScript Verification Pattern:

// 1. Execute mutation
const mutation = await synter.campaigns.updateBudget({
  campaign_id: targetCampaignId,
  platform: 'google',
  daily_budget: newBudget,
});

if (!mutation.success && mutation.error) {
  throw new Error(`Mutation rejected by gateway: ${mutation.error}`);
}

// 2. Post-Write Readback
const refreshed = await synter.campaigns.list({ platform: 'google' });
const verified = refreshed.campaigns?.find(c => c.id === targetCampaignId);

if (!verified || Number(verified.daily_budget) !== newBudget) {
  throw new Error(`Readback verification failed: Expected daily budget $${newBudget}, got ${verified?.daily_budget}`);
}

5. Security & Operating Controls

• Zero Model Training: Customer metrics, search keywords, customer PII, and ad creatives are never used to train frontier models.
• KMS AES-256 Token Vault: Ad account OAuth tokens are stored in KMS-encrypted vaults with automated token refresh.
• Blast-Radius Isolation: Agents can be launched with --read-only (or SYNTER_READ_ONLY=true) to mechanically deregister all write tools at the local client layer.
• Append-Only Audit Log: Every tool call, prompt trigger, and budget change generates an immutable ledger event visible in the Synter dashboard.
