What is Elytra Billing?
Elytra Billing is usage-based billing for AI products, APIs and agents. You charge per token, row, second or call, customers approve a spending cap from their wallet, and usage settles in USDC on Solana.
How much does Elytra Billing cost?
0.75% of each settlement, with no fixed fee per charge. A $0.10 charge costs $0.00075 to collect.
Can AI agents pay for API usage?
Yes. An agent approves a spending cap from its own keypair. At the cap it receives an HTTP 402 and can top up, wait or re-authorise.
What happens if Elytra is unreachable?
Your requests are still served. Usage events are idempotent and queued for retry, so late usage settles late instead of being lost.
