Question 1

What is Satelink?

Accepted Answer

Satelink is programmatic infrastructure for autonomous AI agents and automated systems to discover digital services, evaluate options, and access APIs through controlled, machine-readable workflows. It is operated by Jakuraa Commercial Private Limited (incorporated in 2019 in Coimbatore, India).

Question 2

Who is Satelink designed for?

Accepted Answer

Satelink serves AI agent developers building autonomous workflows, software teams requiring pay-per-call infrastructure without recurring subscription lock-in, quantitative researchers, and enterprises requiring verifiable, auditable API procurement.

Question 3

What is agent procurement?

Accepted Answer

Agent procurement is the automated discovery, evaluation, authorization, access, metering, payment, and settlement for digital services by software agents. Satelink provides machine-readable specifications and payment rails that allow autonomous systems to procure supported APIs programmatically.

Question 4

What role does machine commerce play?

Accepted Answer

Machine commerce is software paying software for services. Satelink provides the rails a machine uses to discover a priced API, pay for it programmatically without human credit card checkout, and settle on-chain with verifiable receipts.

Question 5

How do software agents discover Satelink endpoints?

Accepted Answer

Agents discover services programmatically by querying the standard machine-readable manifest at `GET https://rpc.satelink.network/.well-known/satelink.json`. This provides endpoint URIs, schema definitions, supported authentication schemes, and pricing specifications.

Question 6

What is /.well-known/satelink.json?

Accepted Answer

It is an RFC 8615 well-known URI that returns an immutable machine-readable catalog of Satelink's available production endpoints, current pricing contracts, and supported payment rails.

Question 7

Does Satelink support the Model Context Protocol (MCP)?

Accepted Answer

Yes. Satelink publishes an open MCP server package (`@satelink/mcp-server`) that enables Claude Desktop and other MCP-compliant AI clients to discover services, inspect catalog methods, and execute approved queries directly.

Question 8

What authentication methods does Satelink support?

Accepted Answer

Satelink supports two primary authentication modes: 1) Keyless x402 authorization using signed EIP-712 headers in USDC on Base, and 2) Developer API keys (`sat_live_...`) funded with prepaid USDT credits on Polygon PoS.

Question 9

Do I need an account to call Satelink services?

Accepted Answer

No account or human signup is required for keyless x402 calls. A software agent can pay per call directly using on-chain authorization. For developer API keys with custom rate ceilings, key registration is available via the developer console.

Question 10

What are the rate limits for developer API keys?

Accepted Answer

Newly provisioned developer keys start with a rate limit ceiling of 500 calls per day. This ceiling can be increased upon request for high-throughput enterprise workloads.

Question 11

How much does Satelink RPC cost?

Accepted Answer

Polygon PoS JSON-RPC access is priced at a flat rate of $0.000030 per call. Keyless bundles via x402 are priced at $0.10 for 1,000 calls in USDC on Base. There are zero dynamic surge multipliers.

Question 12

Is there a free tier of calls?

Accepted Answer

There is no anonymous free tier. Every unauthenticated request receives an immediate HTTP 402 challenge. Keys start with a 500 calls/day rate limit ceiling and require deposited USDT credits or keyless x402 payments to execute.

Question 13

How are credits deposited and tracked?

Accepted Answer

USDT deposits are committed on-chain to the `RevenueVaultV2` contract on Polygon (chain ID 137). Each call decrements the balance atomically in the epoch metering ledger.

Question 14

What is x402?

Accepted Answer

x402 is an open protocol standard built around the HTTP 402 Payment Required status code. It allows an API server to challenge an incoming request with pricing requirements, and allows a client to pay keylessly per call in USDC on Base (chain ID 8453).

Question 15

How does an agent pay keylessly?

Accepted Answer

When the agent receives HTTP 402, it signs an EIP-712 authorization payload containing the quoted amount and nonce, attaches it to the `X-Payment` header, and retries the request. The facilitator verifies the signature and streams the response immediately.

Question 16

Which network is used for x402 settlement?

Accepted Answer

x402 micropayments settle on Base L2 (chain ID 8453) using native USDC for minimal transaction fees and fast confirmation times.

Question 17

Which blockchain networks are supported for RPC?

Accepted Answer

Satelink operates high-throughput JSON-RPC infrastructure for Polygon PoS mainnet (chain ID 137). Support for additional chains will be announced in official release notes.

Question 18

What RPC methods are supported?

Accepted Answer

Standard Ethereum execution and query methods are supported, including `eth_blockNumber`, `eth_getBlockByNumber`, `eth_call`, `eth_getTransactionReceipt`, and `eth_getLogs` within bounded block ranges.

Question 19

What is the status of the node operator program?

Accepted Answer

The node operator program is paused. Operator payouts are not active, and new node registrations are not currently accepted.

Question 20

Does Satelink hold customer funds?

Accepted Answer

No. Satelink is strictly non-custodial. Broker funds remain with your authorized broker, and withdrawals are never enabled. Machine payments execute directly via user-funded wallets or prepaid credit vaults.

Question 21

What is the status of Satelink Trading AI?

Accepted Answer

Satelink Trading AI is the first intended application built on the platform. It operates in controlled paper-trading beta; live execution is not yet available. AI models propose suggestions, while deterministic risk engines and signed mandates decide.

Question 22

Is any content on Satelink investment advice?

Accepted Answer

Nothing on these pages is investment advice or a recommendation to buy or sell anything. Trading can lose money, including all of it. Simulated and hypothetical results do not predict real results, and nobody can promise any outcome.
