Use Case

Autonomous Agent Self-Upgrade

An AI agent detects it has reached its API quota, evaluates pricing tiers, submits a USDC payment on Polygon, and receives an upgraded API key — all without human intervention. FeedOracle is the first compliance oracle designed for this flow end-to-end.

What the Agent Does

Detects quota exhaustion via 429 or quota header.
Calls /usdc/pricing — reads available tiers.
Selects target tier, calls /usdc/intent.
Transfers USDC on Polygon to the payment address.
Calls /usdc/verify — receives new API key.
Resumes work with upgraded access. No human involved.

The Flow in Detail

FeedOracle historically exposed a minimal machine-to-machine self-upgrade mechanic in which an agent could discover tiers and settle in USDC autonomously. This is a legacy / controlled-access capability and is not offered as a public self-serve USDC checkout; it carries no public pricing.

For current plans and checkout, see /pricing.html. For programmatic or controlled access, contact sales.

Production Evidence

This flow is live and has been executed in production. The transaction below is the first autonomous USDC upgrade on FeedOracle:

TX Hash: 0x2be6dd56aed6e45f5bacb0af53b95e7cded8b36885aabba12cb7bac282f95905
Network: Polygon Mainnet
Asset: USDC (native Circle)
Result: Pro tier API key issued, all 25 MCP servers active

Every upgrade transaction is anchored on-chain and verifiable by any third party — the audit trail is not a log file, it is the blockchain.

What the Agent Gains

25,000 API calls/day (up from 100 on Free)
500 cryptographic proof artifacts/month
Full MCP server access across all 3 servers
Priority rate limits for compliance pipelines

Why This Matters

No human approval loop — agents operate 24/7
Payment is on-chain — verifiable by auditors
No credit cards, no invoices, no procurement cycles
Designed for MiCA-era pipelines that cannot pause

M2M Discovery Protocol

Agents that follow the MCP standard can auto-discover the full payment flow without prior configuration. FeedOracle publishes machine-readable metadata at:

/.well-known/mcp/server-card.json — full capability manifest including payment endpoints
/.well-known/oauth-protected-resource — resource metadata for M2M auth
/.well-known/openapi.json — OpenAPI v7.1 with all USDC payment paths documented

A compliant agent needs no documentation — it reads the server card, finds the USDC endpoints, and executes. This is the internet-native B2B payment model for AI infrastructure.

Verify Independently

FeedOracle publishes a public verification script that any agent or auditor can run:

curl -O https://feedoracle.io/feedoracle_agent_verify.py
python3 feedoracle_agent_verify.py
# Expected: 38/38 checks passed

No login. No funnel. Copy, paste, verify.
