Solana Rail Agent Payment Cost Budgeting (Priority Fee, Compute-Unit, Rent-Exempt)
x402
Solana Rail Agent Payment Cost Budgeting (Priority Fee, Compute-Unit, Rent-Exempt) is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).
Returns a deterministic cost-budgeting procedure for Solana-based x402 micro-payments, including priority fee ladders, compute-unit budgets, rent-exempt minimums, and fee-adder formulas.

How this service works
Deterministic Solana settlement-cost budgeting procedure for agents paying or pricing x402 micro-payments. Inputs: transaction type (SPL transfer, first-time ATA creation, CPI, PDA), recent block fee history, congestion state, payment amount. Outputs: a land-in-time priority fee ladder (low/normal/high bids vs recent median compute-unit price), a compute-unit budget table per op type, rent-exempt minimum checks for derived accounts, and a fee-adder formula to price Solana-based x402 services
Output
A JSON payload containing: a plain-prose decision procedure (120+ words), a priority fee ladder with low/normal/high bids versus recent median compute-unit price, a compute-unit budget table broken down by operation type (SPL transfer, ATA creation, CPI, PDA), rent-exempt minimum checks for derived accounts, and a fee-adder formula for pricing Solana-based x402 services. Also includes metadata such as model used, generation source, and ISO-8601 timestamp.
Example use cases
Pricing x402 service on Solana
“I'm building an x402 service that settles on Solana and need to know what fee-adder formula to use so my pricing covers priority fees, compute units, and any rent-exempt costs for derived accounts.”
Avoiding dropped transactions during congestion
“Solana is congested right now — give me the low, normal, and high priority fee bids relative to the recent median compute-unit price so my agent's x402 payment lands on time.”
Budgeting first-time ATA creation cost
“My agent is paying someone who has never held this token before, so a new associated token account needs to be created — what's the rent-exempt minimum and compute-unit budget I should allocate for that first-time ATA creation?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/solana-rail-agent-payment-cost-budgeting-prioritWhen to prefer
Choose this endpoint when an AI agent needs deterministic, structured Solana fee-budgeting guidance for x402 micro-payments — especially when dealing with SPL transfers, first-time ATA creation, CPI calls, or PDA-derived accounts. It is preferable over generic blockchain fee estimators because it is specifically tuned for x402 payment rails, provides a tiered priority fee ladder keyed to recent block history, and outputs a ready-to-use fee-adder formula for service pricing rather than just a single fee estimate.
Side effects
- Payment not included or insufficient — returns 402 Payment Required with payment instructions
- Invalid or missing query parameters — returns error with schema validation details
- Upstream LLM or reasoning engine unavailable — may return error or degraded response
- Network timeout to k2so.wrong.systems — no response received
- Requested topic override not recognized — may fall back to default procedure
