Pricing

Proxagora uses per-call pricing. You pay for what you use in USDC. No subscriptions. No seats. No minimum commitment.

How It Works

Each API in the catalog has a fixed per-call cost in USDC. You see it in the discovery endpoint:

{
  "id": "ip-geo",
  "cost_usdc": 0.001,
  ...
}

That's the exact amount you pay per successful call. Failed calls (4xx from upstream, validation errors) are not charged.

Price Range

Current catalog pricing:

| Tier | Cost | Example APIs | |------|------|-------------| | Micro | $0.001 | IP Geo, WHOIS, Weather, Exchange Rates | | Low | $0.002–0.005 | Email Validation, Tech Stack, News Search | | Mid | $0.01 | SERP Results, Email Finder, URL Screenshot | | High | $0.02+ | LinkedIn Enrichment, Company Data |

Most useful APIs for agents sit in the $0.001–0.01 range. A budget of $1 USDC covers 100–1000 API calls.

Payment Methods

x402 (USDC on Base)

Pay per call in real time via Base Sepolia (testnet) or Base mainnet.

• Gas cost per transaction: ~$0.001–0.005 USD equivalent
• No minimum balance
• On-chain proof of every call
• Works autonomously — agents pay without human involvement

Stripe MPP (Card)

Pre-fund a credit balance with a card. Calls deduct from balance.

• Minimum top-up: $5 USD
• No gas overhead
• Better for developer testing and teams without Base wallets
• No blockchain required

Pre-Funded Credits (Planned)

For high-volume agents: fund a USDC balance on Proxagora in one transaction, then calls deduct from it without per-call on-chain transactions. This removes latency and gas overhead.

• Removes per-call gas cost
• Sub-millisecond payment resolution
• Coming Q2 2025

Take Rate

Proxagora charges a 20% take rate on each API call.

If an API costs $0.01 USDC:

• Provider receives: $0.008 USDC (80%)
• Proxagora fee: $0.002 USDC (20%)

The price you see in the catalog is the all-in price. No hidden fees.

As a Provider

If you publish an API:

• You set the per-call price in USDC
• Proxagora takes 20%
• You receive 80% per call, settled to your Base wallet
• Settlement runs hourly (minimum 10 USDC threshold)

There are no listing fees, monthly charges, or setup costs. If your API gets no calls, you pay nothing.

Cost Estimation

Single agent

# Estimate costs for an agent workflow
calls_per_run = {
    "ip-geo": 10,
    "domain-reputation": 5,
    "email-validation": 20,
    "serp-results": 3
}

costs = {
    "ip-geo": 0.001,
    "domain-reputation": 0.005,
    "email-validation": 0.002,
    "serp-results": 0.01
}

total = sum(calls_per_run[api] * costs[api] for api in calls_per_run)
print(f"Per run: ${total:.4f} USDC")
# Per run: $0.1150 USDC

runs_per_day = 100
print(f"Per day (100 runs): ${total * runs_per_day:.2f} USDC")
# Per day (100 runs): $11.50 USDC

Comparison

| Approach | Example Cost | Overhead | |----------|-------------|---------| | Proxagora x402 | $0.001–0.02 per call | Gas: ~$0.001/call | | Proxagora Stripe MPP | $0.001–0.02 per call | None | | Traditional API (individual keys) | Varies, often subscription | Account management per provider | | Building your own scrapers | Infrastructure cost | Maintenance, reliability |

Refunds

API calls that return 4xx or 5xx from Proxagora's own infrastructure (not from upstream) are not charged. If you're charged for a call that errored on our side, contact support@proxagora.com with the request timestamp and we'll issue a credit.

Upstream errors (your called API returns 500) are charged — the network cost was incurred.

Testnet Pricing

Base Sepolia (testnet) uses the same price structure with test USDC. Test USDC is free from Circle's faucet — there's no cost to test at full scale before moving to mainnet.
