Obscura

The rail, explained

The paymentrail for AI agents.

Your agent gets a spending account. You fund it in rupees. It settles in stablecoins on Solana — one API call at a time.

Section II — How it works

Fund once. Spend per call. Settle on Solana.

Three parties, one rail. You put rupees in at the top; agents and API providers move stablecoins at the bottom. Every step is auditable.

01 · The operator

You fund, once.

Top up with UPI or card. Obscura converts it to USDC on Solana in under 30 seconds and credits your agent's wallet.

WhenOne-time action
Moves₹ → USDC
₹500 → $6.00 USDC

02 · The runtime

Your agent spends.

Every API call your agent makes is paid for automatically, on-chain, per request — no wallet code, no manual approvals, no crypto knowledge.

WhenPer API call · Automatic
Moves~0.008 USDC / call
0.008 USDC / call

03 · The seller

API providers get paid.

Merchants plug in one middleware line. USDC lands in their payout wallet on every request — or they cash out to a bank via Dodo.

WhenPer request · Settles on-chain
MovesUSDC → INR (v2)

Section III — The SDK

A spending account in three lines.

Drop @obscura-app/sdk into your agent. The wrapped fetch() now has a budget, a signer, and a paper trail.

  • No wallet code. The SDK ships a remote signer that calls our backend on 402.
  • No retry logic. Payments settle, the request replays with X-Payment.
  • No surprise spend. Per-agent monthly caps, enforced before every signature.

Section IV — Audiences

Two sides of the rail. Pick yours.

01 / Operators

Building agents

Ship autonomous software that pays its own way.

  • One SDK call replaces wallets, signers, and payment loops.
  • Monthly spend caps per agent, enforced at signature time.
  • UPI and card top-ups via Dodo — GST-compliant, MoR-backed.
  • A dashboard that shows every rupee in and every 0.008 USDC out.
02 / Merchants

Selling APIs

Monetize per call. No invoicing, no chasing.

  • One middleware line returns 402 + quotes the price.
  • x402-solana settles on-chain before your handler runs.
  • USDC accrues in a dedicated payout wallet — no custody risk.
  • Cash out to bank via Dodo payouts (v2) or swap yourself today.

Section VI — The market, now

Agent commerce isn't theoretical.

It's already happening. Obscura is the rail between the 900M Indians who transact in rupees and the agents that transact on Solana.

Section VII — FAQ

Questions, fielded in order.

No. Every agent gets a server-derived Umbra encrypted token account, provisioned on sign-up. Your users fund it with UPI or card. They never see a seed phrase or a browser extension.

USDC on Solana devnet today, USDG on mainnet once it lists. The mint is set via env — swapping is a one-line change, and the SDK never cares which token it is.

The operator. Each agent's Umbra-side keypair is derived server-side from a master seed (HMAC-SHA-256, domain-separated per subject) and never leaves Obscura's backend. Every outgoing transfer runs through a spend-cap check before signing. No cap, no signature.

The signer rejects further transactions with a clean 402 back to the agent, and the operator gets a dashboard alert. Caps are set per-agent and enforced off-chain in v1; the v2 roadmap migrates them into an Anchor program for trustless enforcement.

Free during private beta. Production pricing is 2% platform fee on the fiat leg plus ~1% network + FX, surfaced upfront on the top-up screen. Merchants receive the full USDC amount minus Solana fees.

900M internet users, UPI as the default rail, and Dodo Payments as an MoR that handles GST, compliance, and payouts out of the box. That's a distribution edge Stripe + Bridge + Tempo don't have here. International support follows the same architecture.
